7XV5654-0BA00
The optical signal, the high precision second pulse from the GPS-Receiver 7XV5664-
0AA00 for the differential protection relay 7SD52, is received at input R2. This signal is
optically to electrically converted to 24 V and given out at PIN 4/8 at X1. The telegram
received at R1 is converted also and seen on PIN 1/3 of X1. Because a semiconductor
output is used for both signals no significant delay between input and output is
produced. With the Y-bus cable 7XV5105-0AAxx up to 6 SIPROTEC devices 7SD52
can be connected. Light idle state ´ON´ at the optical input lead to a 24 V electrical
signal. A second pulse signal at R2 is indicated by LED „RCV 2"at the front plate.
The Pin-assignment of Port A of the relay 7SD52 is equal to that on X1.
Synchronizing by the binary input of the Sync.-Transceiver
Instead of receiving an optical input signal at R1 or R2, also binary input BI2 can be
used as pulse input. This binary input has an input voltage range from 24-250 V DC.
The pick up voltage can by increased from 17 V to approx. 70 V by a jumper X100 in
the Sync.-Transceiver (position 2-3). The pick up and drop off time of the binary input is
approx. 5 ms each. Thus no microsecond accuracy is reached by that input.
