  • PCS-9785 Satellite-Synchronized Clock (Extension)

  • The RCS-9785E is a timing signal expansion unit without an internal GPS module. It receives IRIG-B standardized timing code from external GPS timing sources, decodes and converts timing codes, and then outputs expanded timing signals to the whole station. The expanded timing signals are IRIG-B signals, pulse per second (PPS) signals, pulse per minute (PPM), pulse per hour (PPH) signals and timing messages.

  • Remote supervision

This device supports local SCADA and remote control centre communcation in using of protocols such as IEC 61850 to realize the device running status supervision.

  • Time service

This device supports GPS ( Global Positioning System) and BDS ( BeiDou Navigation Satellite ). In addition, it supports antenna transmission link-based time delay compensation.

  • Recording

Automatically, this device stores all the self-diagostic record, binary status change and service log in its internal storage.

  • Output clock synchroniztion signal

The kinds of output clock synchronization signal is rich, including PPS ( Pulse Per Second ), PPM ( Pulse Per Minute ), PPH ( Pulse Per Hour), IRIG-B signal, timing message ( serial), SNTP/NTP timing message (network), IEEE 1588 signal, etc.

  • High accuracy
    This device accuracy is high in long term. The punctual error is less than 1us per hour.
  • Signal accuracy 
    This device provides several reception channels for IRIG-B signal via its optical port or RS-485/422 port. In addition, it supports link-based reception time delay compensation.
  • IEEE 1588 protocol

This device supports the IEEE 1588 protocol (BC mode and OC mode) for clock synchronization.

  • SNTP/NTP protocol

This device supports the SNTP/NTP protocol and can work as a network time server.
