7XV5654-0BA00
Synchronizing of maximal 6 SIPROTEC 4 devices via input R1
At the optical 820 nm input R1 an IRIG-B or DCF77-telegram from the GPS receiver
7XV5664-0AA00, which is designed for SIPROTEC 4 devices, is received. This optical
signal is converted to a corresponding electrical signal. This is switched to an electric
semiconductor output to a 9-pin Sub-D socket X1 to PIN 1 (+24 V) and PIN 3 (-24 V).
This output is pin-compatible to the IRIG-B input (24 V) of the SIPROTEC 4 devices
(Port A). With the Y-bus cable 7XV5104-0AAxx up to 6 SIPROTEC 4 devices can be
connected to the electrical output and can be synchronized with the time telegram.
Light idle state ´ON´ at the optical input leads to an 24 V electrical signal at the
semiconductor output. The data transfer via input R1 is indicated by the yellow „RCV
1" LED at the front plate. The 24 V voltages for the GPS-Receiver 7XV5664-0AA00 is
supplied from the wide range power supply unit 7XV5810-0BA00, which is connected
with its U input at the DC-voltage of the station battery or an AC power supply.
