15.3.3 PR120/K signalling module
1 ris tic s
The module enables the local signalling alarms and circuit-breaker trips.4 haracteristics the igital input
The unit enables the digital input associated with the following functions:
- enabling alternative set parameters, set (PR123/P only);
- outside trip control;
- zeroing release trips;
- resetting PR120/K contacts;
- local/remote enabling;
- resetting energy meters.
For the load control function, the module can used actuator.2 Front view

The digital input activated 24VDC 20% voltage. 47.3.
The two configurations are alternative each other. You can switch from one configuration the other without changing the module, using
a different wiring, illustrated the wiring diagrams figs.
There are two possible configurations for the SIGNALLING module:
- default configuration: digital input, contacts with pole common, independent contact;
- alternative configuration: independent contacts.
