The pulse length should be long enough to securethe breaker opening.For three-phase tripping logic common 3-phase output, SMPPTRC has a single input(TRIN) through which all trip output signals from the protection functions within theIED, 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 IEDsbinary outputs, as well as to other functions within the IED requiring this signal.Section 11 1MRK 511 287-UEN ALogic342Technical manual
