Binary inputs

The binary inputs can be used, for example, to generate a blocking signal, to unlatch
output contacts, to trigger the disturbance recorder or for remote control of protection
relay settings.
Binary inputs of slot X120 are available with configuration A.

Outputs

Outputs for tripping and controlling

Output contacts PO1, PO2, PO3 and PO4 are heavy-duty trip contacts capable of
controlling most circuit breakers. In the factory default configuration, the trip signals
from all the protection stages are routed to PO3 and PO4.
