Time synchronization in substation
Time synchronization in substation
(OP)
I have to synchronize time for two relays: SIEMENS 7SD522 and ABB REL670. REL670 can use PPM (Pulse per Minute) signal through an itput but I do not know that 7SD522 can use the same PPM signal. Does 7SD522 also use PPM signal through an input? or It uses PPS (Pulse per Second) signal?

Open Settings/Time Synchronization
From Drop-down menu "Sourse of time synchronization" choose "External Impulse via Binary Input"
From Drop-down menu "Pulse via binary input" choose one you have wired.
Press OK, download in the relay and order one beer

It may be like this in theory and practice, but in real life it is completely different.

My order code for 7SD522 is 7SD5221-5DB99-7FK0-L0R-M3A. Does my 7SD522 support IRIG?
