GPS TIME SERVER FOR NETWORK TIME SYNCHRONIZATION

GPS TIME SERVER
× GPS SYNCHRONIZED CLOCK SYSTEMS

GPS Time Server (SYNTIME) is capable for the time synchronization requirements in various industries like power, process, IT, telecommunications etc. It generates wide range of time code and pulse signals via different output ports like 1PPS, IRIG-B TTL/AM, NTP, Serial (RS232/RS485), PTP, Fiber ports.

GPS Time Server (SYNTIME) has redundant and non-redundant options for Power supply and GPS receiver functionality. SYNTIME has a 16 x 2 LCD display for viewing of time parameters, status of GPS receiver parameters, discrete LEDs provide at-a-glance status and health information. The GPS receiver has built-in RT on board backed up with battery to maintain time during power loss and instant recovery on power resumption.
