Product overview
SYN4505 The standard synchronous clock is a multifunctional clock device designed and developed by Xi'an synchronous Electronic Technology Co., Ltd., which is equipped with a high-precision constant temperature crystal oscillator 0CXO. It receives the Beidou two generation /GPS/GLONASS satellite signal and IRIG-B code signal, selects the satellite signal priority, uses the external timing signal to synchronize the machine, generates the AC and DC IRIG-B code signals, time, minutes and seconds pulse signals, NTP network timing, serial port time information and 1PPS (second signal) synchronization pulse signal. It is a practical electronic instrument for the power system to establish the time scale and realize the time synchronization.
Key word GPS satellite synchronous clock, synchronous clock system, GPS timing system, time synchronization system.
Product function
1) The external reference input signal includes one satellite signal and two IRIG-B (DC) signals.
2) Satellite selection function: there are six choices: GPS Beidou mixed time service, GPS&GLONASS mixed time service, Beidou GLONASS mixed time service, single GPS time service, single Beidou time service, single GLONASS time service to meet customer's demand for satellite signal timing.
3) Work mode: including automatic mode, manual mode, punctual mode and so on three modes, wherein the automatic mode indicates that the satellite signal is selected first, and then selects the IRIG-B signal; the manual mode indicates that the external reference is manually selected by the user; the time keeping mode indicates that the external reference is not received, and the internal oscillator is used to carry out the time keeping.
4) System setup function: users set up baud rate, time zone and delay by pressing key.
5) Output IRIG-B AC and DC signals, output 5 RS232C serial port, output 5 1PPS, 5 1PPM;
6) One Lu NTP network timing function;
7) Dry contact alarm function: it has 5 alarm functions, namely, fault alarm, satellite alarm, IRIG-B (1) alarm, IRIG-B (2) alarm, out of step alarm.
8) Automatically save various configuration states to meet all kinds of customer needs.
Product characteristics
