Product Overview

Time Server module is specifically designed for SICOM3028GPT series which support PTP protocol. This module supports GPS (Global Positioning Service), BDS (Chinese Satellite System), and GLONASS (Russian Satellite System) as sky time sources and IEEE1588 PTP (Precision Timing Protocol), IRIG-B as ground time sources.

It also supports IEEE1588 PTP (Precision Timing Protocol), NTP (network Time Protocol), IRIG-B time output based timing devices and synchronization systems. This module supports TMS features to report system status by IEC61850 MMS and GOOSE publisher and GOOSE subscriber to trigger and monitor time status. It also supports SNMP and WEB management.

By expanding this module, SICOM3028GPT can work as a grandmaster clock and provide high precision clock when the satellite signal is temporarily lost.

Key Features
  • High Precision Reference Clock as Absolute Time Source (GPS, BDS, GLONASS)
  • Relative Reference Time and External Time Synchronization (PTP, IRIG-B)
  • High precision stable OCXO oscillator with excellent time keeping performance
  • Support PTP,NTP/SNTP,IRIG-B,PPS output
  • Report time status by IEC61850 MMS, IEC60870-5-104, DNP over TCP etc
  • Support Web, SNMP etc. management system
  • Designed for the SICOM3028GPT-L2GT, SICOM3028GPT-L2FT, SICOM3028GPT-L3GT, SICOM3028GPT-L3FT chassis
  • Support hot-swap for easy maintenance (only can replace the same type of module)
