The IED outputs are categorized as power outputs (POx) and signal outputs (SOx).
The power outputs can be used for starting and stopping the motor. The signal outputs
are not heavy-duty outputs. They are used for alarm or signalling purposes.

Hardware channel Usage
PSM PO1 Master Trip 1 (generator circuit breaker open)
PSM PO2 Generator circuit breaker close enable signal
PSM PO3 Master Trip 2 (generator circuit breaker open)
PSM PO4 Operate from directional over power protection
PSM PO5 Operate from differential protection
PSM PO6 Operate from frequency protection
PSM SO1 Common generator circuit breaker operate signal
PSM SO2 Common generator circuit breaker start signal
PSM SO3 Generator circuit breaker trip circuit and monitoring alarm
The IED measures the analog signals needed for protection and measuring functions
via galvanically-isolated matching transformers. The matching transformer input
channels 1…7 are intended for current measuring, and the channels 8...10 for voltage
measuring.
