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 X130 are available with AIM0006 module.

Outputs
4.2.1
Outputs for tripping and controlling
Output contacts PO1, PO2, PO3 and PO4 are heavy-duty trip contacts capable of
controlling most circuit breakers. On delivery from the factory, the trip signals from
all the protection stages are routed to PO3 and PO4.
