Coupling link for PLC
9.10.1
Description
Thanks to a low control power (< 0.5 W) and an operating range of 17 to 30 V DC, the
coupling link enables a size S0 contactor with a 24 V DC operating mechanism to be
connected directly to the PLC output. The control voltage for the coupling link and the rated
control supply voltage for the contactor are galvanically isolated. An LED indicates the
switching state of the coupling link. The coupling link features an integrated surge
suppressor (varistor) for the contactor coil being switched.
The coupling link is available in the following versions:
● 3RH2914-.GP11: Can be mounted onto the front on 3RT2 contactors (size S00 to S3);
spring-loaded connection or screw-type connection
● 3RH2924-1GP11: Can be mounted from above on 3RT2 contactors (size S0) without
increasing the installation depth; screw-type connection; comprises 3RT2926-4RA11 coil
terminal module and coupling link
Note
The 3RH2914
-1GP11 coupling link is also suitable for front-mounting on 3RH2 contactor
relays (size
S00).
