NTP time synchronization server uses GPS signal as the time source, and can also choose Beidou, B code, CDMA, atomic clock and other time sources. The NTP time synchronization server product adopts a fully modular structure design, which not only achieves full board compatibility, but also provides rich signal interface resources and an open special interface design platform, with excellent compatibility capabilities. It can provide multiple NTP/SNTP signals, PTP signals, pulse signals (1PPS/M/H, empty contact, differential, TTL, 24V/110V/220V active, optical), IRIG-B signals (TTL, 422, AC, Optical), DCF77 signal, time message (RS232, RS422/485, optical), which can meet the time synchronization interface requirements of different devices and are widely used in electric power, finance, communications, transportation, radio and television, security, petrochemical, metallurgy, water conservancy, National defense, medical care, education, government agencies, IT and other fields. Time synchronization server equipment is produced using surface mount technology and controlled by high-speed chips. It has high precision, good stability, strong functions, no accumulated errors, is not restricted by environmental conditions such as regional climate, high cost performance, simple operation, and maintenance-free. Features, suitable for unattended use.
