CT-TSS2000 Time Synchronization System CT-TSS2000 Time Synchronization System consists of CT-TSS2000 Grandmaster and CT-KZ001 Time Code distributor. Each grandmaster receives GPS or BD as well as external IRIG-B time signal. While the optional CT-KZ001 time code distributors are synchronized by a CT-TSS2000 Grandmaster. The whole system supports multi-format outputs, can meet the demands of various industrial users, is a stable and reliable time synchronization system widely used in power , telecom networks, railways and other fields etc. Functions Multiple time signal input: BD B1, GPS L1, IRIG-B code Multi-format outputs: NTP, SNTP, IRIG-B, Serial and Pulse 1x 10/100 Base-T Ethernet interface for management Internal precision time-keeping via high precision oscillator Support IEC61850, IEC60870-5-104 standard Fault alarm functions for time source, board cards, power supply and so on. Grid frequency measurement function is optional Time delay compensation mechanism, compensation range: 20ns~500ms Time continuity judgment mechanism to avoid output time discontinuity Features Support multiple time sources selection Flexible module card design, easy for outputs configuration Support duplex, hot standby, cold standby configuration LCD display with man-machine interaction brings a simple operation Adapt to the strong electromagnetic interference environments Redundant Dual power supplies 19’’ / 3U rack mount Specifications - Grandmaster Time Reference: BD B1, GPS L1,IRIG-B Outputs: IRIG-B TTL?RS422/RS485?RS232?fiber?idle contact Pulse (1PPS, 1ppm, 1PPH) TTL?RS422/RS485?RS232?fiber?idle contact NTP/SNTP RJ45 Serial(TOD) RS232 Network management RJ45 Time Performance: Time Accuracy to UTC =1µs(RMS) Holdover Accuracy =55µs /hr (Lose of GPS after 12hours) Network Services: Network Interface 10 / 100M RJ45 Ethernet port, ST fiber port NTP time sync accuracy 1ms ~ 10ms (depending on the network environment) NTP access ability 2000 requests per second Protocols RFC-1059(NTP v1),RFC-1119(NTP v2),RFC-1305(NTP v3),RFC-5905(NTP v4), RFC-2030(SNTP) TELNET, HTTP, (SSH,DHCP,FTP are customizable) IEC61850, IEC60870-5-104 Installation 19 "/ 3U standard chassis Note: the CT-KZ001 Time Code Distributor receives 2 lines IRIG-B time signal from the Grandmaster as time reference, if any loss of the both 2 lines IRIG-B signal, the internal oscillator will keep working to ensure normal time output.
