The timing device (standard synchronous clock, time synchronization equipment, Beidou time server) uses signals as the time source. At the same time, Beidou satellites, B codes, rubidium atomic clocks, signals and other clock sources can be selected to ensure time synchronization accuracy. Da.
Jinan Weishang Electronics Co., Ltd.'s products are produced using surface mount technology and are controlled by high-speed chips. They have high precision, good stability, strong functions, high cost performance, no accumulated errors, are not restricted by environmental conditions, and are simple to operate. , fully automatic intelligent operation, maintenance-free and other characteristics, suitable for unattended operation. Applications: substations, power plants, hydropower projects, industrial control systems.
Functional features of the timing device
. Can provide multiple pulse signals (, air contact, differential, active, optical), time message (RR/, optical), B signal ( ,,, optical), signal,/protocol network clock synchronization signal, protocol signal, frequency time synchronization signal, which can meet the timing interface requirements of different devices.
. Parallel channel receiver channel Beidou satellite reception is optional.
3. The panel displays Beijing time, date, number of visible satellites, group pulse programming status, and baud rate.
.Second pulse and minute pulse output have one level each for testing.
.Network timing function R Ethernet interface and client timing software are optional.
.Four buttons to set or modify working parameters, view internal data, and the set working parameters will not be lost when power is turned off.
.The number of pulse empty contacts and the number of B code output interfaces can be further expanded.
.The device adopts a fully modular plug-and-play structure design, supports hot-swappable boards, flexible configuration, and easy maintenance. It also provides convenience for adding or changing timing signal interfaces during future power plant/substation renovation and expansion.
