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.

Outputs for signalling
SO output contacts can be used for signalling on start and tripping of the IED. On
delivery from the factory, the start and alarm signals from all the protection stages are
routed to signalling outputs.
