3TX71 Plug-in Relays
Selection
Siemens offers a wide range of plug-in relays to meet your
industrial 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:

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 preset 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.
HOne 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 preset 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.
