Recently, our company has producedNTP network synchronous clock successfully put into operation at Meishan Environmental Center in Sichuan Province

Produced by Shanghai Ruicheng Electric Co., LtdKseriesNTPNetwork synchronous clock(Beidou)GPSDual machine backup time synchronization system, GPSTime synchronization system,Beidou network timing server with built-in high-performanceGPSReceiver and Beidou receiver, fully hardware designed, fanless, stable and reliable equipment.

NTPNetwork synchronous clockThe signal interface

(1) 1External reference input:GPSBeidou receiver;

(2)Time code output interface: The device not only achieves full compatibility with the board, but also provides rich signal interface resources and an open special interface design platform, with compatibility capabilities. The device can provide multiple pulse signals（1PPSThe1PPMThe1PPHEvent, null contact, differentialTTLThe24V/110V/220VActive, optical)IRIG-BSignal（TTL、422、232TheAC(Light)DCF77Signal (active, passive), time message（RS232TheRS422/485(Light)PTPTheNTP/SNTPNetwork time signal can meet the needs of power plants/Requirements for timing interfaces of different equipment in the substation.

(3)Satellite loss of lock, power interruption alarm dry contact signal

NTPNetwork synchronous clockThe functional characteristics of

1High time accuracy, reaching30nS.

2The device adopts a fully modular plug and play structure design, supports hot swapping of boards, has flexible configuration, and is easy to maintain. For future reference sources of other signals(Jialilu satellite signal and upstream ground linkDCLSSignalPTPTheNTPTime reference signal, etc)The access provides convenience and lays the foundation for the future construction of a three in one digital synchronous network. At the same time, it provides convenience for adding or changing timing signal interfaces during future on-site renovation and expansion.
