Temperature Monitoring Relays

3RS10/3RS11

Overview

The 3RS1/3RS2 SIMIREL tem-

perature monitoring relays can

be used for measuring temper-

atures in solid, liquid and gase-

ous media. The temperature is

acquired by the sensor in the

medium, evaluated by the

device and monitored for over-

shoot, undershoot or within a

range (window function). The

family consists of analog

adjustable devices with one or

two threshold values and digital

devices that represent an

excellent alternative to thermo-

stats in the low-end perform-

ance range. The output relay

picks up and releases at the

threshold values in accord-

ance with the parameter set-

tings.

Analog evaluation units

• Sensor types: PT100/Type J/

Type K

• Measuring principle for 2- and

3-wire sensors

• Electrical isolation between

sensor and supply voltage

(with the exception of AC/DC

24 V devices)

• Separate designs for over-

shoot and undershoot

• Measuring range depending

on the version for

-50 °C to +50 °C,

0 °C to 100 °C,

0 °C to 200 °C,

0 °C to 600 °C or

500 °C to 1000 °C

• Potentiometer for adjustable

limit temperature and hystere-

sis of 2 to 20%

• Closed-circuit principle

• Narrow 22.5 mm enclosure

with 12 terminals

With one threshold value

• Supply voltage for

AC/DC

24 V or AC 110/230 V

• Indication of supply voltage

and relay status via LEDs

• One NO and one NC contact

With two threshold values

• Additional potentiometer for

ϑ2 (hysteresis for second limit

value is 5 % of the measuring

range)

• Supply voltage for

AC/DC

24 V or 24 to 240 V

• LED indication of supply volt-

age and both relay states

• Open-circuit/closed-circuit

principle switchover

• One NO and one CO contact

Digital evaluation units

• High-end evaluation unit for

1 or 1-3 sensor circuits

• Multifunctional digital display

and three LEDs (for threshold

values and Ready)

• Adjustable sensor types

• Adjustable overshoot, under-

shoot or window function

• Switchable open-circuit or

closed-circuit principle

• Hysteresis for both threshold

values (1 to 99 K)

• Memory function can be se-

lected by means of an external

control signal (Y1/Y2)

• One NO and two SPDT con-

tacts

• Adjustable time delay from 0to

999 s

• Wire-break and short-circuit

detection with separate signal-

ling contact (1 NO)

• Non-volatile storage of the set

parameters

• 45 mm housing with

24 supply terminals

• Measuring principle for 2- and

3-wire sensors

• Electrical isolation (with the ex-

ception of AC/DC 24 V devic-

es)

• In the 3-sensor design, the sta-

tus of the individual sensors is

indicated on limit value over-

shoot/undershoot

It clearly displays which of the

connected sensors has overshot

or undershot one or both thresh-

old values.

Advantages

• All devices are with Cage

Clamp terminals

• All devices with the exception

of AC/DC 24 V devices are

electrically isolated

• Variants for the evaluation of

1 to 3 sensors in one unit, e.g.

for multiple monitoring in a

plant or for motor protection

• Easy operation without complex

menu systems

• Graduated product range; the

right device for every applica-

tion

• High-end evaluation units with

digital display – can be used

for a wide temperature range

and for different sensor types

• Adjustable hysteresis

• Rapid fault diagnosis due to

short-circuit monitoring and

sensor wire-break detection

• Power packs with wide range

of input voltage reduce the

number of variants

• Easy configuration for either

two-point or three-point closed-

loop control

Application

The 3RS1/3RS2 SIMIREL tem-

perature monitoring relays can

be used in almost any applica-

tion in which limit tempera-

tures must not be overshot or

undershot, e.g.:

Monitoring of set limit temper-

atures and output of alarm

messages for:

• Motor and plant protection

• Switchgear cabinet tempera-

ture monitoring

• Frost monitoring

• Temperature limits for proc-

ess variables, e.g. in the

packaging industry or galva-

nising equipment

• Control of plants and ma-

chines such as heating, air-

conditioning and ventilation

systems, solar collectors,

heat pumps or warm water

supplies

• Monitoring of servo motors

with KTY sensors

• Bearing and gearbox oil-lev-

el monitoring

• Monitoring of

cooling liquids

Analog setting evaluation devices with one and two

threshold values. For analog setting devices, the

threshold values and the hysteresis from 2 to 20% are

set using a rotary potentiometer. For devices with 2

threshold values, the selectable hysteresis only acts

on threshold value 1. For the second threshold value,

the hysteresis is permanently set to 5%. This series of

products was developed for applications where a setting

accuracy of ± 5% is sufficient.

Evaluation units with digital settings

Temperature monitoring relays distinguish themselves

due to the fact that they are extremely easy-to-use.

The actual temperature is always displayed on the three-

digit LED display. A dedicated relay with one NO contact

is integrated to monitor the sensor.

The relay is switched-out in the parameterizing mode.

The following parameters can be set:

• Sensor type

• 2 threshold values J , J

• 1 hysteresis; this acts on both thresholds (0–99 K)

• 1 delay time; this acts on both thresholds (0–9999 s)

• Either the open-circuit/closed-circuit principle can be

selected

• Function: Overtemperature/Undertemperature

(overrange/underrange) or window monitoring within

a defined range

Versions with a wide-range voltage have electrical

isolation.

The temperature ranges are dependant on the sensor

type (refer to the function).

Connection of resistance thermometers

2-wire measurement

When 2-wire temperature sen-

sors are used, the sensor re-

sistance is added to the wire

resistance. The system error

that results must be taken into

account when the parameters

are set for the evaluation unit. A

jumper must be clamped

between terminals T2 an T3.

The following table can be used

to determine the temperature

error when a PT100 is used.

Error due to wiring

The error that arises due to the

wiring is approx. 2.5 Kelvin/

ohm. If the resistance of the wir-

ing is not known and cannot be

measured, the wiring error can

be estimated by means of the

following table.

3-wire measurement

To minimise the effects of the

wiring resistances, a 3-wire cir-

cuit is usually used.

Using the additional wire, it is

possible for two measuring cir-

cuits to be formed of which one

is used as a reference.

The evaluation unit can then

automatically calculate the wir-

ing resistance and take it into

account.

Connection of thermoelements

A differential temperature

measurement is obtained from

the thermo-electrical effect

between the measuring point

and the evaluation unit.

This principle assumes that the

evaluation unit knows the tem-

perature at the terminal (T2).

The 3RS11 temperature moni-

toring relays have a built-in ref-

erence point correction function

that determines this reference

temperature and uses it to gen-

erate the measurement result.

The absolute temperature is

therefore calculated from the

ambient temperature of the

evaluation unit and the temper-

ature difference measured by

the thermoelement.

In this manner, temperature

acquisition (T1) is possible

without knowing the precise

ambient temperature at the ter-

minals of the evaluation unit

(T2).

The connecting lead is only

permitted to be extended using

equalising conductors made

from the same material as the

thermoelement itself. If a differ-

ent type of lead is used, the

measurement will be inaccu-

rate.

tion with PT100 sensors and 20°C ambient temperature, in K

Temperature overshoot

elpicnirp tiucric-desolCelpicnirp tiucric-nepO

Digital evaluation units:

After the temperature has reached the set

threshold value ϑ1, output relay K1 changes

its switching state appropriately as soon as

the set time t has elapsed (K2 responds to ϑ2

similarly).

Analog evaluation units:

When the set threshold value is reached, out-

put relay K1 changes its switching status. For

devices with 2 threshold values, relay K2

responds to the second set threshold value.

As soon as the temperature reaches the

respective set hysteresis value, the relays

return immediately to the original state.

A time delay cannot be set

(t = 0).

When the temperature has reached the upper

threshold ϑ1 and the set delay time t has

elapsed, the output relay K1 changes its

switching state. As soon as the temperature

reaches the respective set hysteresis value,

the relay returns immediately to the original

state.

In the same manner, K2 responds to the lower

threshold value of ϑ2.

Principle of operation with memory function, based on the example of temperature overshoot using the closed-circuit principle

When the temperature has reached the set

threshold ϑ1 and the set delay time t has

elapsed, the output relay K1 changes its

switching state (similarly, K2 responds to

ϑ2.)

The relays will only return to the original state

when the temperature has fallen below the

respective set hysteresis value and the con-

nection Y1-Y2 was briefly interrupted.

3RN10 00 compact tripping

unit

The compact unit is equipped

with a red LED (TRIPPED) to indi-

cate tripping and a SPDT con-

tact.

After the device has tripped, it is

reset automatically after the ther-

mistors have cooled down. The

common contact of the SPDT

contact is connected to the con-

trol voltage

This device is particularly suit-

able in circuits in which the con-

trol circuit and signalling circuit

are at the same potential, e.g. in

local control boxes.

3RN10 10, 10 11, 10 12 stan-

dard tripping unit

The standard units are equipped

with two LEDs (READY and

TRIPPED) and with 1NO and

1NC for switch-off and signalling.

They are available with automatic

RESET (3RN1010), manual RE-

SET (3RN1011) or manual/auto-

matic and remote RESET (3RN10

12). The 3RN1012 unit holds on

supply failure. If the control volt-

age fails, a previous trip will be

memorised.

A remote RESET function is im-

plemented by connecting an ex-

ternal pushbutton with an NO

contact to terminals Y1 and Y2. If

terminals Y1 and Y2 are bridged,

tripping is followed by an auto-

matic RESET.

3RN10 13 multifunction trip-

ping unit

In the 3RN10 13 thermistor mo-

tor protection tripping units, the

sensor circuit is also monitored

for a short circuit. Tripping due to

a short circuit is indicated by a

flickering red LED. The

monostable design also indi-

cates a wire-break in the sensor

circuit by flashing of the red LED.

The 3RN10 13 tripping unit is

equipped with manual, remote

and automatic RESET functions.

The TEST/RESET button can be

used to manually reset the trip-

ping unit.

A remote RESET function is im-

plemented by connecting an ex-

ternal pushbutton with an NO

contact to terminals Y1 and Y2. If

terminals Y1 and Y2 are bridged,

tripping is followed by an auto-

matic RESET.

3RN10 22 tripping unit "Warn-

ing and switch-off"

Two sensor circuits can be con-

nected to one 3RN10 22 tripping

unit and act on one output relay

with 1 NO for warning and 1 SPDT

for switch-off. The functions

"Warning" and "Switch-off" are im-

plemented by means of tempera-

ture sensors with different rated

response temperatures TNF. Acti-

vation of the sensor circuit for

"Warning" is indicated by a yellow

LED and for "Switch-off" by a red

LED.

The sensor circuits have different

reset responses:

• "Warning" (terminals 2T1, T2)

automatic RESET only

• "Switch-off" (terminals 1T1, T2);

changeover from manual RE-

SET to automatic RESET by

bridging terminals Y1 and Y2.

A remote RESET function is im-

plemented by connecting an

external pushbutton with an

NO contact.

3RN10 62 tripping unit "Multi-

ple motor protection"

Up to six sensor circuits can be

connected to one 3RN10 62 trip-

ping unit which all act on one out-

put relay. Simultaneous protec-

tion of several motors (up to 6) is

an advantage in the case of

group drives (e.g. if a motor is

overloaded, all motors in the

group can be switched off). Apart

from the red LED "TRIPPED" that

indicates the switching status of

the tripping unit, a LED is as-

signed to each sensor circuit that

is lit when the associated sensor

circuit trips. Sensor circuits that

are not required must be short cir-

cuited.

The reset response of the

3RN10 62 tripping units can be

changed from manual RESET to

automatic RESET by bridging

terminals Y1 and Y2.

A remote RESET function is im-

plemented by connecting an ex-

ternal pushbutton with an NO

contact.

Application

The 3RN1 thermistor motor pro-

tection tripping units are thermal

protective devices that can be

used in conjunction with PTC

thermistors Type A for the tem-

perature monitoring of electrical

drives, transformer windings,

oils, bearings, air, etc.

Principle of operation

The 3RN1 tripping units operate

according to the closed-circuit

principle and therefore monitor

themselves for a wire-break. A

temporary voltage drop of less

than 200 ms (for devices with a

wide input voltage range < 100

ms) will not cause a change in

status of the auxiliary contacts.

The 3RN10 13 multifunction trip-

ping unit also features short-cir-

cuit detection in the sensor cir-

cuit. The unit will trip if a short cir-

cuit arises in the sensor circuit

(resistance in sensor circuit

<20 ). The tripping units feature

electrical isolation between the

3RN10 12-2C...

"Relay switched"

LED to indicate

"Voltage applied"

Test and Reset buttons

control circuit and sensor circuit

in the case of AC and UC control

supply voltages (for DC control

supply voltage: no electrical iso-

lation). For units with a TEST but-

ton, the function of the device

can be checked by pressing the

button for longer than 2 s.

Safe electrical isolation

All electrical circuits (outputs,

control circuit, sensor and

Reset circuit) of the 3RN1013-

1BW10 multifunction

tripping unit (wide input voltage

range, monostable output

relay and screw terminals) are

safely isolated from each other

up to a rated voltage of 300 V

acc. to DIN VDE 0100 Part 410/

DIN VDE 0106/DIN VDE 0160.

Notes

.For DC-activated tripping

units, electrical isolation must

be provided using a battery

system or a safety isolating

transformer to DIN VDE

0551.

.When tripping units with an

automatic RESET function

are used in EEx e zones, the

control circuit must be de-

signed to ensure that the

monitored machine cannot

restart autonomously.

.In the case of tripping units

without short-circuit detec-

tion, the sensor circuit must

be measured with a suitable

measuring instrument during

commissioning. For resis-

tance < 50 Ohm, the sensor

circuit must be checked for a

short circuit.

.When the 3RN10 00 unit (no

Ready LED) and the

3RN10 13-1BW01 unit (no

change in switching status

for the auxiliary contacts on

control voltage failure) are

used to protect EEx e mo-

tors, separate monitoring of

the control voltage is recom-

mended.

conjunction with PTC ther-

mistors acc. to DIN VDE 0660

Parts 302 and 303 and

DIN 44 081/DIN 40 082 for di-

rect temperature monitoring of

explosion-protected motors of

the "Increased safety" EEx e and

must be routed as separate con-

trol cables. It is not permitted to

use cores of the motor supply

cable or other main supply ca-

bles. If extreme inductive or ca-

pacitive interference is expected

to be generated by heavy cur-

rent cables routed in parallel,

shielded control cables must be

used.

With the tripping units, tempera-

ture sensors with characteristics

according to DIN VDE 0660 Part

303, DIN 44 081 and DIN 44 082

(e. g. EPCOS AG single and tri-

ple sensors, Type No. B 591.. or

B 593 ..) can be used.

The number of temperature sen-

sors that can be connected in

series is dependent on the total

cold resistance. The total cold

resistance must not exceed

1.5 kΩ.

Installation

The 3RN1 tripping units are

suitable for snapping on to

35 mm standard mounting rails

acc. to DIN EN 50 022 or for

screw mounting using adapters.

Any mounting position is possi-

ble.

Specifications

The tripping units are suitable for

use in any climate and safe from

touch to DIN VDE 0106 Part 100.

The 3RN1 tripping units meet the

requirements of the basic techni-

cal standard EN 50 081-2;

IEC 61000-6-2 "Electromagnetic

compatibility of I&C equipment

in industrial process engineer-

ing" and DIN VDE 0660 Parts

302 and 303, IEC 60 034-11-2

Section 1 and 2 "Built-in thermal

protection of rotating electrical

machines, thermal detectors

and tripping units" and "PTC

thermistors and tripping units".

The terminal designations of the

auxiliary contacts complies with

EN 50 005.

Protecting the windings of

three-phase transformers

To protect the windings of three-

phase dry transformers with PTC

thermistors in cases where the

operating voltage of the ther-

mistor motor protection tripping

unit must be tapped from the

mains voltage, a 3RN10 22 ther-

mistor protection unit for warning

and tripping and, for example, a

3RP15 time relay can be used.

The auxiliary contactor K4 oper-

ates on the shunt release of the

high-voltage circuit-breaker.

Working principle for trans-

former protection

When voltage is applied to the

line-side of the transformer, the

voltage on the secondary side

rises to the final value within

1.5 s. The 3RN1 tripping unit

does not trip until 0.8 x Us, so as

long as the operating voltage is

applied to the closed contacts

95-98 on contactor K4, it would

cause breaking of the

circuit-breaker via its shunt re-

lease.

In order to prevent this, the volt-

age is only applied to terminals

07 and 95 once the 3RN1 trip-

ping units have definately

picked up and the auxiliary

switches have switched to the

"Ready" position. The K3 and K4

contactors are not controlled un-

til the respective rated response

temperature TNF of the sensor is

exceeded.

The tripping unit should be

switched to "Automatic RESET"

(jumper must be placed be-

tween terminals Y1 and Y2). This

ensures that the 3RN1 tripping

unit is reset when the transformer

is reconnected following trip-

ping.

The time-delay relay is set to a

delay time of ≥ 1.5 s.

to 240 V UC even in the case of DC operation.

2) Devices with short-circuit detection in the sensor circuit. Up to this maxi-

Standards, specifications

The time relays comply with:

IEC 60 721-3-3 "Environmen-

tal conditions"

IEC 61 812-1/DIN VDE 0435

Part 2021 "Electrical relays,

time relays"

IEC 61 000-6-2/EN 50 081-1

"Electromagnetic

IEC 60 947-5-1; DIN VDE

0660 Part 200 "Low-voltage

switchgear and controlgear"

Application

Time relays are used in control,

starting protective and control

circuits for all switching opera-

tions involving time delays.

They guarantee a high level of

functionality and a high repeat

accuracy of timer settings.

Housing design

All time relays are suitable for

snap-on mounting onto 35 mm

standard mounting rails

according to EN 50 022 or for

screw fixing.

Configuration

Changing the time setting

ranges and the functions will

only be effective when being

carried out in de-energised

state

Start input B1 or B3 must only

be triggered when the supply

voltage is applied

The same potential must be

applied to A1 and B1, or A3

and B3

With the two-voltage version,

only one voltage range must

be connected

The activation of loads parallel

to the start input is not permis-

sible when using AC control

voltage (see adjacent dia-

grams)

Surge suppression is inte-

grated in the time relay. This

prevents supply voltage

spikes occurring when the

relay switches. No damping

mechanisms have been inte-

grated for the contacts

The 3RP15 05-.R should not

be used near heat sources

3UG Monitoring Relays

for line, single-phase voltage

and insulation monitoring

The new 3UG4 line monitoring relays permit a

maximum degree of protection to be achieved

for machines, plants and systems. This means

that line and voltage faults can be detected early

on and the appropriate response is initiated before

far more significant subsequent damage can occur.

Measured quantity Possible plant or system fault

Phase sequence • Direction of rotation of the drive

Phase failure • A fuse has blown

• Control supply voltage has failed

• Single-phase operation of a motor with the corresponding overheating

Phase dissymmetry • Motor overheating as a result of non-symmetrical voltages

or phase failure

• Line supplies with non-symmetrical load are detected

• A phase failure is detected in spite of regenerative feedback

Undervoltage • Motor draws an increased current and in turn overheats

• A device is undesirably reset

• Line supply dips, especially when supplied from a battery

• Threshold value switch for analog signals 0 to 10 V

Overvoltage • A plant is protected against destruction due to

supply overvoltages

• A plant or system switches-in above a certain voltage

• Threshold value switch for analog signals 0 to 10 V

Insulation monitoring • The insulation resistance for non-grounded plants and systems is monitored

Your advantages:

• Thanks to the wide voltage range, it can be used on all line

supplies around the world – from 160 V to 690 V – without

an auxiliary voltage

• Can be variably set to above range, below range or window

monitoring

• Freely parameterizable delay times and reset behavior

• Reduced width for all versions for line and voltage monitoring

• For the digital versions, the actual value and fault type are

permanently displayed

• Automatic direction of rotation correction by differentiating

between line faults and incorrect phase sequence

• All versions have removable terminals

• All versions have either screw terminals or alternatively

innovative Cage Clamp terminals

Applications:

The applications are listed in the following table. These tables

indicate the various plant system conditions that can be detected

using the monitoring parameters.

Return voltage due to coupling between the individual phases

Loads connected to the three-phase line supply – such as motor windings,

lamps, transformers – result in a coupling between the individual phases.

As a result of this coupling, there is always a return voltage at the equip-

ment terminal of the phase that has failed.

Monitoring the load of motors and the func-

tionality of electronic loads – a clear case for

our 3UG relays that monitor current and cos .

These devices detect the effect of wear and

faults early on. This means that the appropriate

actions can be taken before far more signifi-

cant damage can occur.

3UG Monitoring Relays

for single-phase current

and cos monitoring

Current monitoring:

• Wide-voltage versions reduce stock inventory costs

• Only two versions from 2 mA to 10 A

• Can be variably set to overrange, underrange or

window monitoring

• Freely parameterizable delay times and reset switch

• Actual value and fault type are permanently

displayed

• All of the versions have removable terminals

• All of the versions have screw terminals or,

alternatively, innovative Cage Clamp terminals

cos monitoring:

• cos is monitored for overrange and underrange

• Fault memory that can be switched-in

• Selectable starting bypass and delay time

for threshold value out of range

Applications:

The applications can be seen in the adjacent table.

These tables show the various plant/system states

can be detected using the monitoring parameters.

Your advantages:

• 22.5 mm wide

• Can be digitally set and with LCD display

• Fault memory that can be switched-in

• Simultaneous monitoring for current

overrange/underrange over the complete

measuring range

Wiring diagram for 24 V AC/DC (only 3UG46 2.-.AA30)

From the following circuit diagrams it is clear that loads in mea-

suring circuits have to be in the current flow upstream from the

monitoring relay. Otherwise, the monitoring relay could be de-

stroyed and the short-circuit current could cause damage to the

plant.

Configuring note:

A2 and M are electrically connected internally!

For applications in which the load to be monitored and the mon-

itoring relay are supplied from the same power supply, there is

no need for connection A2!

The load current must always flow through M or the monitoring

relay may be destroyed!

Insulation monitoring

Overview

SIRIUS 3UG45 8. insulation monitor

Isolation monitoring relays are used for monitoring the insulation

resistance between ungrounded single or three-phase AC sup-

plies and a protective conductor.

Ungrounded, i. e. isolated networks (IT networks) are always

used where high demands are placed on the reliability of the

power supply, e. g. emergency lighting systems. IT systems are

supplied via an isolating transformer or by power supplies such

as batteries or a generator. While an initial insulation fault be-

tween a phase conductor and the ground effectively grounds the

conductor, as a result no circuit has been closed, so it is possible

to continue work in safety (single-fault safety). However, the fault

must be rectified as quickly as possible before a second insula-

tion fault occurs (e. g. according to DIN VDE 0100-410). For this

purpose insulation monitoring relays are used, which constantly

measure the resistance to ground of the phase conductor and

the neutral conductor, reporting a fault immediately if insulation

resistance falls below the set value so that either a controlled

shutdown can be performed or the fault can be rectified without

interrupting the power supply.

Overview

SIRIUS 3UG45 81 insulation monitor

The 3UG45 81 insulation monitoring relays are used to monitor

insulation resistance in accordance with IEC 61557-8 in un-

grounded AC networks with rated voltages of up to 400 V.

These devices can monitor control circuits (single-phase) and

main circuits (three phase).

They measure insulation resistances between system cables

and system ground. If the value falls below the threshold value,

the output relays are switched to fault status.

In the case of 3UG45 81 a higher-level DC measuring signal is

used. The higher-level DC measuring signal and the resulting

current are used to determine the value of the insulation resis-

tance of the network which is to be measured.

Overview

SIRIUS 3UG45 82 and 3UG45 83 insulation monitors

The 3UG45 82 and 3UG45 83 insulation monitoring relays are

used to monitor insulation resistance in ungrounded IT AC or DC

networks in accordance with IEC 61557-8.

They measure insulation resistances between system cables

and system ground. If the value falls below the threshold value,

the output relays are switched to fault status. With these devices,

which are suitable for both AC and DC networks, a pulsed test

signal is fed into the network to be monitored and the isolation

resistance is determined.

The pulsed test signal changes its form according to insulation

resistance and network loss capacitance. The changed form is

used to predict the changed insulation resistance.

If the predicted insulation resistance matches the insulation re-

sistance calculated in the next measurement cycle, and is lower

than the threshold value, the output relays are activated or deac-

tivated, depending on the device configuration. This measure-

ment principle is also suitable for identifying symmetrical insula-

tion faults.

3UG49 83 voltage reducer modules

The 3UG49 83 passive voltage reducer module can be used to

allow the 3UG45 83 insulation monitoring relay to be used for in-

sulation monitoring of IT networks with rated voltages of up to

690 V AC and 1000 V DC.

3TX0 interface relays are available in two basic

versions. The 3TX7004/05 is just 6.2 mm wide:

This series means that the interface relays take

up a lot less space in the electrical cabinet.

Then there is our 3TX7002/03 series: These de-

vices are suitable for mounting in small electri-

cal cabinets with a low depth and short distances

between the mounting rails. Both series are

available with an extensive range of input and

output interfaces.

3TX70 interface relays

Interface relays as input or output coupler

Your advantages: 3TX7002/03 and 3TX7004/05

• Operating range from 0.7 to 1.25 Vs at 24 V DC

up to 60 °C

• Protective circuit is integrated in the input

• Connection comb and cable to connect voltages at the

same potential

• Manual-0-automatic switch for easier commissioning

Your advantages: 3TX7014 and 3TX7015

• Plug-in relays that can be quickly replaced with

preassembled wiring

• Conductors are introduced and clamped from the front

– therefore shorter wiring times

• Tested, complete devices reduce installation times

• Individual relays are available as spare parts

• Relay version with hard-gold-plated contacts –

therefore achieving a high contact reliability

Applications:

• Electrically isolation

• Voltage conversion – e.g. from 24 V DC to 230 V AC

• Signal amplification

• Contact multiplication

• General relay controls

• Overvoltage and EMC protection of controls

Engineering information:

When selecting the interface for rated control supply volt-

ages of 110 V AC and 230 V AC, the maximum permissible

cable length must be carefully observed. The special

3TX700- 05 relay can be used for longer cables.

Interface modules are available either with relays or

semiconductors. Semiconductor interfaces offer some

significant advantages: The electronic components

are extremely reliable and have an extremely long

service life (refer to the diagram below). The input in-

terface combines the best of both worlds – improved

technical features and a lower price. When consider-

ing output interfaces, the question of “relay or

semiconductor” needs to be taken into account as well

as the making/breaking capacity and the number of

operating cycles. If a relay has to be replaced just once

during the complete lifetime of a machine, then a semi-

conductor interface will already have paid for itself.

Your advantages:

• Favorably priced and reliable: Input interfaces with

semiconductor output

• Graduated series of output interfaces with semiconductors

• Extremely long electrical life

• Extremely high contact reliability

• High DC making/breaking capacity

• Short switching times

Applications:

• Providing electrical isolation, converting voltages

• Switching DC loads

• Switching capacitive loads

• High number of switching cycles

• Overvoltage and EMC protection of controls

Technical data

1) The semiconductor output switches off in the

case of a short-circuit or overload. Before the

device can be operated again, it must be dis-

connected briefly from the supply voltage.

2) The current is limited by the semiconductor out-

put in the case of a short-circuit or overload. 3) Below the minimum load current, the built-in

semiconductor detects a wire-break in the load

circuit. To reset this, the control circuit must be

briefly deactivated.

DIN VDE 0411 Part 500,

In the case of coupling ele-

ments in double-tier design, the

terminals are arranged in two

tiers and the devices are

extremely narrow. Connection

technique: Screw terminal or

Cage Clamp. Versions with

Manual-0-Automatic switches

are available for test purposes.

The input and output coupling

devices differ with regard to the

location of the connections and

LEDs. For equipment identifica-

tion purposes, each coupling

device has a blank legend

plate.

Similar to the technical data of

the solid-state systems, the

devices have a low power con-

sumption.

Mounting instructions

Snap-on mounting onto hori-

zontal and vertical standard

rails is possible. For a vertical

rail and closely mounted devic-

es, the permissible ambient

temperature is

Tu = 40°C. Any service position

is possible.

When the permissible upper

limit of rated control supply volt-

age is fully exploited as well as

the highest permissible ambi-

ent temperature, and the de-

vice operates with a continuous

24-hour (100%) ON period, it is

recommended that no devices

of a similar type or other devic-

es with a high external temper-

ature are mounted adjacently

without appropriate gaps; oth-

erwise the service life of the

coupler can be reduced.

A gap of > 10 mm on the left-

hand and right-hand sides of

the device reduces the risk of

premature failure under these

conditions of application.

Optocouplers switch by means

of semiconductors. These are

not subject to wear, so welding

of contacts is not possible.

The 6.2 mm wide optocouplers

have an opening on the right-

hand side of the enclosure.

They can be – like the relay

couplers – mounted in a row

without gaps.

Surge suppression

The coupling devices are

tested with 1 x 105 operating

cycles in AC-15 operation with

the values specified in the tech-

nical data. The service life of

the relay connector can be

increased by connecting induc-

tive loads.

Note

When capacitive loads are

switched in the absence of

components (series resistors)

that limit the brief peak cur-

rents, this can cause micro

welding of the relay contacts.

To guarantee shock hazard protection in modules of the 6.2 mm series

with enclosure opening (e. g. 3TX7 004-3AB04), the individual module or

the final module in a row must be fitted with an end plate.

Overview

Application

In automation and closed-loop

control, working with analog

signals is unavoidable. Inter-

faces of 0 to 10 V and 0/4 to 20

mA have become established

in this field. Interface convert-

ers load the coupling function

for analog signals on the input

side as well as on the output

side. They are indispensible

where analog values are pro-

cessed with electronic con-

trols. In the harsh industrial

environment, signals often have

to be transferred over large dis-

tances. Electrical isolation is

necessary due to the various

different power supplies. Poten-

tial differences and losses due

to cable resistance must be

prevented. Electromagnetic

disturbances and overvoltages

can affect the signals espe-

cially at the input end and even

destroy the analog modules.

With regard to the output, short-

circuit protection is of particular

importance.

The devices are EMC-tested

acc. to EN 50081 (emission)

and EN 61000-6-2 (immunity).

The analog signals correspond

to IEC 60 381-1/2.

Converters are used in analog

signal processing for:

• Electrical isolation

• Conversion of normalised and

non-normalised signals

• Amplification, impedance

adjustment

• Conversion to frequency for

processing by a digital input

• Overvoltage and

EMC protection

• Short-circuit protection

of the outputs

Configuration

Active interface converters

Active interface converters offer

the widest application flexibility

due to the use of an external

supply voltage. Project engi-

neering with active interface

converters is easy, because

input and output resistances

and voltage drops are bal-

anced by the auxiliary power.

They provide pure electrical

isolation as well as conversion

between the different signal

types or amplification. The load-

ing on the encoder is negligible.

Passive interface converters

Passive interface converters do

not require an external supply

voltage. This advantage can

only be utilised in the case of

current signals that are trans-

ferred 1:1. Amplification or

conversion is not possible.The

converters are used for clear

electrical isolation of signals

and for protecting the inputs

and outputs. Passive discon-

nectors do not operate reac-

tion free, i.e.any load on the

output affects the input signal

to the same degree. When the

passive converter is used, an

analysis of the output power of

the encoder and the input

resistance of the analog input

must be performed. For pure

currentis being used more and

more.

Calculation aid for passive converters

.Important:

When passive disconnectors

are used, it is important to note

that:

The current-driving voltage of

the measuring transmitter UE

must be sufficient to drive the

maximum current of 20 mA

through the passive disconnec-

tor with a voltage drop of UV =

2.7 V and the resistive load RB.

This means that:

UB≥ UE = 2.7 V + 20 mA x RB

Voltage splitting with passive disconnectors

The following diagram shows

the input voltage UE as a func-

tion of the resistive load RB tak-

ing into account the voltage

drop UV

. If the resistive load is

known, the minimum voltage

that the current source has to

produce in order to drive the

maximum current of 20 mA via

the passive disconnector and

resistive load can be read off

the Y-axis.

Input voltage

as a function of resistive load at IA = 20 mA

Current-carrying capacity of

the outputs

A maximum output load is

specified in the case of current

signals. This resistance value

specifies the maximum input

resistance for the subsequent

device for which the output of

the converter is adequate.

For voltage signals, the maxi-

mum current that can be drawn

from the output is the decisive

factor.

2-way isolation

In the case of 2-way isolation,

the input is electrically isolated

from the output. The "zero

potential" for the supply volt-

age is the same as that on

which the analog output signal

is referenced.

3-way isolation

In the case of 3-way isolation,

each circuit is electrically iso-

lated from the others, i.e. the

input, output and supply volt-

age have no common potential.

3TG10 power relays

Version

The 3TG10 contactors with 4

main contacts are available

with screw-type terminals or

with 6.3 mm to 0.8 mm tab con-

nectors. The designs with

screw-type terminals are suit-

able for use in any climate and

safe from touch to

DIN VDE 0106 Part 100.

The 3TG10 contactors have a

compact design. Their overall

width is 36 mm.

They are suitable for use in

household appliances as well as

for distribution boards in offices

and residential buildings, owing

to their hum-free construction.

They can further be used in all

areas where there is only a lim-

ited amount of space available,

e.g. in air conditioners, heating

systems, pumps and fans - basi-

cally in all simple electrical con-

trols.

AC and DC operation

EN 60 947-4-1

(VDE 0660 Part 102).

Surge suppression

The 3TG10 contactors are fitted

with an integrated protective cir-

cuit for damping opening

surges.

Overload and short-circuit pro-

tection

The 3UA7 overload relay can be

used for overload protection

(see NS E catalogue, available

in German). This applies both

for contactor mounting and for

RELAYS

Siemens offers a wide range of plug-in relays to meet your indus-

trial needs. Basic style relays are the most economical and are

equipped with a mechanical flag indicator only . Premium style

relays are full featured with LED and mechanical flag indication,

push to test button and typically a latching hold down door which

provides a method of activating the contacts without applying

power to the coil. This feature is very handy during comissioning

and troubleshooting. Premium Bifurcated style relays are ideal

for low minimum holding current requirements on the contacts.

Typical minimum holding current for bifurcated contacts is 3mA

instead of 100mA.

Relays are divided up by the following functions for selection:

• Base style

• Contact Arrangement

• Contact Rating

• Coil Voltage

• Optional Features (Basic, Premium and Premium Bifurcated)

Multifunction Timer Modes

Function Name Description

AOn Delay

(Power On)

When input voltage U is applied, timing delay t begins. Relay contacts R change state after the time delay is complete. Contacts R return to their shelf state when

input voltage U is removed. Trigger switch is not used in this function.

BRepeat Cycle

(Starting Off)

When input voltage U is applied, time delay t begins. When time delay t is complete, relay contacts R change state for time delay t. This cycle will repeat until input

voltage U is removed. Trigger switch is not used in this function.

CInterval

(Power On)

When input voltage U is applied, relay contacts R change state immediately and timing cycle begins. When time delay is complete, contacts return to shelf state.

When input voltage U is removed, contacts will also return to their shelf state. Trigger switch is not used in this function.

DOff Delay

(S Break)

Input voltage U must be applied continuously. When trigger switch S is closed, relay contacts R change state. When trigger switch S is opened, delay t begins.

When delay t is complete, contacts R return to their shelf state. If trigger switch S is closed before time delay t is complete, then time is reset. When trigger switch

S is opened, the delay begins again, and relay contacts R remain in their energized state. If input voltage U is removed, relay contacts R return to their shelf state.

ERetrigerable

One Shot

Upon application of input voltage U, the relay is ready to accept trigger signal S. Upon application of the trigger signal S, the relay contacts R transfer and the pre-

set time t begins. At the end of the preset time t, the relay contacts R return to their normal condition unless the trigger switch S is opened and closed prior to time

out t (before preset time elapses). Continuous cycling of the trigger switch S at a rate faster than the preset time will cause the relay contacts R to remain closed. If

input voltage U is removed, relay contacts R return to their shelf state.

FRepeat Cycle

(Starting On)

When input voltage U is applied, relay contacts R change state immediately and time delay t begins. When time delay t is complete, contacts return to their shelf

state for time delay t. This cycle will repeat until input voltage U is removed. Trigger switch is not used in this function.

GPulse

Generator

Upon application of input voltage U, a single output pulse of 0.5 seconds is delivered to relay after time delay t. Power must be removed and reapplied to repeat

pulse. Trigger switch is not used in this function.

H One Shot Upon application of input voltage U, the relay is ready to accept trigger signal S. Upon application of the trigger signal S, the relay contacts R transfer and the pre-

set time t begins. During time-out, the trigger signal S is ignored. The relay resets by applying the trigger switch S when the relay is not energized.

IOn/Off Delay

(S Make/Break)

Input voltage U must be applied continuously. When trigger switch S is closed, time delay t begins. When time delay t is complete, relay contacts R change state

and remain transferred until trigger switch S is opened. If input voltage U is removed, relay contacts R return to their shelf state.

JMemory Latch

(S Make)

Input voltage U must be applied continuously. Output changes state with every trigger switch S closure. If input voltage U is removed, relay contacts R return to

their shelf state.

Overview

Throw is the number of different closed contact positions per

pole. In other words a throw describes the total number of differ-

ent circuits each pole controls.

The following abbreviations are used to indicate contact config-

urations:

SPST Single-pole, single-throw

SPDT Single-pole, double-throw

DPST Double-pole, single-throw

DPDT Double-pole, double-throw

Break is the number of separate contacts the switch uses to

open or close an individual circuits. If the relay breaks the cir-

cuit in one place, then it is a single break relay. If the relay

breaks the circuit in two places, then it is a double break relay.

This illustration shows various contact arrangement types.
