Operation principle

The duration of a trip output signal from tripping logic SMPPTRC is settable
(tTripMin). The pulse length should be long enough to secure the breaker opening.
For three-phase tripping, SMPPTRC has a single input (TRIN) through which all
trip output signals from the protection functions within the IED, or from external
protection functions via one or more of the IEDs binary inputs, are routed. It has a
single trip output (TRIP) for connection to one or more of the IEDs binary outputs,
as well as to other functions within the IED requiring this signal.
