1.1 Overview
The PCS-9785 satellite-synchronized clock is usually used in Substation Automation System (SAS)
to satisfy the time unifying requirements of protection relay, disturbance fault recorder and other
IEDs. Two kinds of PCS-9785 can be adopted to build a higher reliable and accuracy clock
synchronization system in substation. The source clock can receive timing signals from its own
GPS/BDS antenna (Master Mode), while the extension clock receives IRIG-B signals from another
clock source (Slave Mode).
