The network time synchronization server produced by Shanghai Ruicheng Electric Co., Ltd. consists of a standard time synchronization clock body and a time scale signal expansion device, which can be centrally or separately grouped into screens. The time scale signal expansion device includes pulses, time messages, andBThe code extension module and extension device can be combined according to actual needs. The system utilizes the Beidou satellite orIRIG－B(DC)The second synchronization signal and time information sent by the code are transmitted to various systems and automation devices in the power system(Such as dispatch automation systems, microcomputer relay protection devices, fault recorders, event sequence recording devices, remote control devices, etc)Provide accurate time information and time synchronization signals.

Characteristics of Network Time Server

1)Dual configuration synchronous clocks can receive satellite time and external reference time separately, with primary and backup options, achieving mutual backup of time reference signals

Use it.

2)supportNTPTheSNTPNetwork protocol,RJ45Interface, capable of achieving network timing.

3)Standard time code transmission can be set to compensate for transmission delay, so that its standard transmission is not limited by distance media.

4)Remote or local monitoring software makes management and monitoring operations simple and easy, achieving network management.
