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.

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.
