Network time server is a high-tech product for time-calibration of computers and control devices in automation system. Time synchronization server obtains standard time signals from GPS satellite and transmits these information to the equipment (computer, protection) that needs time information in automation system through various interface types. Device, fault recorder, event sequence recorder, safety automatic device and remote RTU can achieve the time synchronization of the whole system.
Network time server is manufactured by SMT surface mounting technology, large scale integrated circuit design and controlled by high-speed chip. It has the characteristics of high precision, good stability, strong function, no accumulated error, no limitation of regional climate and other environmental conditions, high cost performance, simple operation, etc. It can run automatically and intelligently without operation. Maintenance, suitable for unattended and widely used in power, finance, communications, transportation, radio and television, petrochemical, metallurgy, national defense, education, IT, public service facilities and other fields.
