Analog Input module
Analog input modules use an A/D converter to convert sensor voltage,
current, thermocouple or RTD signals into digital data. The digital data is then
translated into engineering units. The analog input modules protect your
equipment from ground loops and power surges by providing opto-isolation
of the A/D input and transformer based isolation up to3,000 VDC.
2.1 ADAM-5013 3-channel RTD input module
The ADAM-5013 is a 16-bit, 3-channel RTD input module that features
programmable input ranges on all channels. This module is an extremely
cost-effective solution for industrial measurement and monitoring
applications. Its opto-isolated inputs provide 3,000 VDC of isolation between
the analog input and the module, protecting the module and peripherals
from damage due to high input line voltage.
Note: Owing to the conversion time required by the A/D converter, the
initialization time of each ADAM-5013 module is 5 seconds. Thus the
total initialization time will be about 20 seconds if all 4 I/O slots in
an ADAM-5000 main unit contain ADAM-5013 modules.

2.2 ADAM-5017 8-channel analog input module
The ADAM-5017 is a 16-bit, 8-channel analog differential input module
that provides programmable input ranges on all channels. It accepts
millivolt inputs (±150mV, ±500mV), voltage inputs (±1V, ±5V and ±10V) and
current input (±20 mA, requires 125 ohms resistor). The module provides
data to the host computer in engineering units (mV, V or mA). This module
is an extremely cost-effective solution for industrial measurement and
monitoring applications. Its opto-isolated inputs provide 3,000 VDC of
isolation between the analog input and the module, protecting the module and
peripherals from damage due to high input line volt- age. Additionally, the
module uses analog multiplexers with active over- voltage protection. The
active protection circuitry assures that signal fidelity is maintained even
under fault conditions that would destroy other multiplexers. This module
can withstand an input voltage surge of 70 Vp-p with ±15 V supplies.

0-2.5 V, ±5 V, 0-5 V, ±10 V and 0-10 V) and current inputs (0-20 mA and 4-20 mA;
requires a 125 ohms resistor). The module provides data to the host
microprocessor in engineering units (mV, V or mA) or two’s complement
format.
Its sampling rate depends on the data format received: up to 100 Hz
(total). Space is reserved for 125-ohm, 0.1%, 10 ppm resistors (See Figure2-9).
Each input channel has 3000 VDC of optical isolation between the outside
analog input line and the module, protecting the module and peripherals from
high input line voltages. Addition- ally, the module uses analog multiplexers
with active over-voltage protection. The active protection circuitry assures
that signal fidelity is main- tained even under fault conditions that would
destroy other multiplex- ers. The analog inputs can withstand a constant 70
Vp-p input with ±15V supplies.

4.1 ADAM-5050 16-channel universal digital I/O module
The ADAM-5050 features sixteen digital input/output channels. Each
channel can be independently configured to be an input or an output
channel by the setting of its DIP switch. The digital outputs are open
collector transistor switches that can be controlled from the ADAM-5000.
The switches can also be used to control solid-state relays, which in turn can
control heaters, pumps and power equipment. The ADAM-5000 can use the
module’s digital inputs to determine the state of limit or safety switches, or to
receive remote digital signals.
Warning!
A channel may be destroyed if it is subjected
to an input signal while it is configured to be
an output channel.

4.7 Counter/Frequency Module
Overview
Compatible ADAM-5000 Series Main Units
ADAM-5080 is a 4-channel counter/frequency module designed to
be implemented within the following Advantech ADAM-5000
series main units:
ADAM-5000/485
ADAM-5510
ADAM-5511
ADAM-5510M
ADAM-5510E
ADAM-5510/TCP
ADAM-5510E/TCP
Please make sure that the ADAM-5080
counter/frequency module is properly inserted into the
compatible main units.
4.7.1 ADAM-5080 4-channel Counter/Frequency Module
With ADAM-5080 4-Channel Counter/Frequency Module, users can
select either counter or frequency mode for data output. ADAM-5080
offers users a variety of very flexible and versatile applications such as
below:
Counter Mode or Frequency Mode
If you want to measure the number of input signals for totalizer function,
you may use counter mode to measure quantities such as movement and flow
quantity. Alternatively, you can also select frequency mode to calculate the
instantaneous differential of quantities such as rotating speed, frequency or
flow rate, and present them in specific engineering formats.
Up/Down or Bi-direction Function
When operating in counter mode, you can choose either the Up/Down
function or the Bi-direction function for different application purposes. The
counter will count up or down according to your applications. This counting
function helps users obtain the most accurate data.
4-22 ADAM 5000 IO modules User’s Manual
Chapter 4
Alarm Setting Function
While in counter mode, you can set alarm status--Disable and Latch. If
you want to disable it, you can select Disable. If Latch status is selected, it
means the Alarm status will be "latched" whenever the alarm being triggered.
Once the alarm status being "latched," it will thereafter stay in that triggered
state. Users will have to issue a "Clear Alarm Status" command to return the
"latched" alarm status back to normal. Users can designate the high-limit
value and low-limit value to regulate your alarm behavior through the utility
program.
Digital Output Mapping
Users can either run the utility program or issue a "Set Alarm
Connection" command to designate a specific digital output module for the
alarm signal to be sent through.

ADAM-5080 Counter/Frequency Mode Selection
Users can select Bi-direction, Up/Down Counter or Frequency option as
shown in Figure 44.
Figure 4-29: Counter / Frequency Mode
Note:
All four channels of ADAM-5080 will operate simultaneously
in the mode you have selected. i.e. If you switch the ADAM5080 to Counter Mode, all four channels will operate in Counter
Mode.
Features -- Counter Mode
Up/Down Counting
The Up/Down Counter Function offers two types of counting:
Up Couting (increasingly) and Down Counting (decreasingly).
Up Counting : when C0A+ and C0A- sense any input signals, the
counter counts up.
Down Counting : when C0B+ and C0B- sense any input signals, the
counter counts down. On receiving Up and Down signal
simultaneously, the counter will not perform each specific counting
accordingly, but will remain at the previous counting value, since
these simultaneous signals won't have any effect on counting
values.
4-25
Analog Input module
Figure 4-30: Wiring for Up/Down Counting
Note:
If you need only one type of counting, connect C0A+ and C0Afor Up Counting only; or connect C0B+ and C0B- for Down
Counting only.
Bi-direction Counting
For implementing Bi-direction Counting, you need to connect
C0B+/D+ and C0B-/D- to implement the control function for Up/Down
Counting. Up Counting : when the input signal is within logic level "1",
the counter value increases.
Figure4-31 : Wiring for Bi-direction Counting
Down Counting : when the input signal is within logic level "0",
the counter value decreases.
Note:
If users select TTL mode and don't connect C0B+ C0B-,
the counter value will increase. If users select Isolated
mode and don't connect C0B+ C0B-, the counter value will
decrease.

Features -- Frequency Mode
If users want to select frequency mode, they can only utilize Up
Counting type, and can only connect to C0A+ and C0A-.

According to your application purposes, you can run the utility program
to set different limit values for High/Low Alarm.

Setting Initial Counter Value
In order to utilize the alarm function, users have to set a high-alarm limit
value and/or a low alarm limit value, and a initial value to fulfill the
requirements for a basic alarm setting.
Figure 4-34: Sending Alarm Signal (recommended settings)
Figure 4-35: Sending Alarm Signal (settings not recommended)
Overflow Value
Overflow value is the number of times the counter value exceeds the
Max/Min values you specified. When the counter value exceeds Maximum value, the overflow value increases; when the counter value goes
under Minimum value, the overflow value decreases. Besides, when the
counter value runs beyond the range of Max/Min value, it will continue
counting from the initial value. Furthermore, if users want to check the
counter value to see if it is higher or lower than the Max/Min value, they
can use the "ReadOverflowFlag" library to gain a readout of the overflow value.
4-28 ADAM 5000 IO modules User’s Manual
Chapter 4
Getting the Totalizer Value
If users want to get the actual counter value, a formula such as follows
can facilitate an easy calculation from the initial counter value, overflow
value and current counter value:
Vtol = {|Vini - Vmin (or Vmax) |+ 1} x |Vvf| + |Vini - Vcur|
Vtol : totalizer value
Vini : initial counter value
Vmin : min. couner value = 0 (fixed value)
Vmax : max. counter value = 2 = 4,294,967,295 (fixed value)
Vvf : overflow value
Vcur : current counter value
32
Example:
If the initial value =10, overflow value =4, min. value = 0, current
counter value = 3, the totalizer value could be calculated as
Totalizer value = {|10 - 0| + 1} x| 4 |+ |10 -3| = 51

ADAM-5511 (with library Version V1.10 or above)
5.1 ADAM-5090 4-port RS-232 Communication Module
Bi-direction Communication
The ADAM-5090 is equipped with four RS-232 ports, which makes it
especially suitable for bi-direction communication. It can simultaneously read
data from other third-party devices such as Bar Code and PLC as long as
these devices are equipped with a RS-232 interface. Furthermore, the ADAM5090 can issue commands to control other devices. It is fully integrated with the
ADAM-5000, ADAM-5500 and ADAM-4000 series, and transmits data to
each other through the RS-232 port. The whole integrated system is an
intelligent stand-alone system and can connect and issue commands to
control devices such as printers and PLCs in remote factory location.
The ADAM-5090 transmits and receives data by polling communication,
and each port can receive up to 128 bytes in the FIFO. For continuous data
longer than 128 bytes, please refer to Table 20 for Baud Rate setting to
avoid data loss.

Analog I/O Modules Calibration
Analog input/output modules are calibrated when you receive them.
However, calibration is sometimes required. No screwdriver is necessary
because calibration is done in software with calibration parameters stored in the
ADAM-5000 analog I/O module‘s onboard EEPROM.
The ADAM-5000 system comes with the ADAM utility software that
supports calibration of analog input and analog output. Besides the
calibration that is carried out through software, the modules incorporate
automatic Zero Calibration and automatic Span Calibration at boot up or
reset.
6.1 Analog input module calibration
Modules: ADAM-5017, 5017H, 5018
1. Apply power to the ADAM-5000 system that the analog input
module is plugged into and let it warm up for about 30 minutes
2. Assure that the module is correctly installed and is properly
configured for the input range you want to calibrate. You can do
this by using the ADAM utility software.
3. Use a precision voltage source to apply a span calibration voltage
to the module‘s V0+ and V0- terminals. (See Tables 5-2 and 5-3
for reference voltages for each range.)
Figure 6-1: Applying calibration voltage
4. Execute the Zero Calibration command (also called the Offset
Calibration command).
6-2 ADAM 5000 IO modules User’s Manual

5. Execute the Span Calibration command. This can be done with the
ADAM utility software.

Analog I/O Modules Calibration
6. CJC Calibration (only for T/C input module)
Figure 6-4: Cold junction calibration
* Note: Zero calibration and span calibration must be completed
before CJC calibration. To calibrate CJC, the thermocouple
attached to ADAM-5018 and a standard thermometer
should be used to measure a standard known temperature,
such as the freezing point of pure water. The amount of
offset between the ADAM-5018 and the standard
thermometer is then used in the ADAM utility to complete
CJC calibration.

6.2 ADAM-5013 RTD Input Resistance Calibration
1. Apply power to the module and let it warm up for about 30 minutes.
2. Make sure that the module is correctly installed and is properly
con- figured for the input range you want to calibrate. You can
use the ADAM utility software to help in this.
3. Connect the correct reference self resistance between the screw
terminals of the ADAM-5013 as shown in the following wiring
diagram. Table 2 below shows the correct values of the span and
zero calibration resistances to be connected.
Reference
resistances used can be from a precision resistance decade box or
from discrete resistors with the values 60, 140, 200 and 440 ohms.
Figure 6-5: Applying calibration resistance
4. First, with the correct zero (offset) calibration resistance connected
as shown above, issue a Zero Calibration command to the module
using the Calibrate option in the ADAM utility software.
5. Second, with the correct span resistance connected as shown
above, issue a Span Calibration command to the module using
the Calibrate option in the ADAM utility software. Note that the
module zero calibration must be completed prior to the span
calibration.
Note:
If the above procedure is ineffective, the user must first issue an
RTD Self Calibration command $aaSi2 to the module and then
complete steps 4 and 5 after self calibration is complete.

6.3 Analog output module calibration
The output current of analog output modules can be calibrated by using
a low calibration value and a high calibration value. The analog output
modules can be configured for one of two ranges: 0-20 mA and 4-20 mA.
Since the low limit of the 0-20 mA range (0 mA) is internally an absolute
reference (no power or immeasurably small power), just two levels are
needed for calibration: 4 mA and 20 mA.
1. Apply power to the ADAM-5000 system including the analog output
module for about 30 minutes.
2. Assure that the module is correctly installed and that its configuration
is according to your specifications and that it matches the output range
you want to calibrate. You can do this by using the ADAM utility
software.
3. Connect either a 5-digit mA meter or voltmeter with a shunt resistor
(250 ohms, .01 % and 10 ppm) to the screw terminals of the module.

4. Issue the Analog Data Out command to the module with an
output value of 4 mA.
5. Check the actual output value at the modules terminals. If this
does not equal 4 mA, use the "Trim" option in the "Calibrate"
submenu to change the actual output. Trim the module until the
mA meter indicates exactly 4 mA, or in case of a voltage meter with
shunt resistor, the meter indicates exactly 1 V. (When calibrating for
20 mA using a voltage meter and shunt resistor, the correct
voltage should be 5 V.)
6. Issue the 4 mA Calibration command to indicate that the output
is calibrated and to store the calibration parameters in the
module's EEPROM.
7. Execute an Analog Data Out command with an output value
of 20 mA. The module's output will be approximately 20 mA.
8. Execute the Trim Calibration command as often as necessary until
the output current is equal to exactly 20 mA.
9. Execute the 20 mA Calibration command to indicate that the
present output is exactly 20 mA. The analog output module
will store its calibration parameters in the unit's EEPROM.
