GPS Time Server – DIN RAIL

GPS Time Server – DIN RAIL

GPS Time Server – GPS-DRM-1010 is a compact DIN rail mountable unit which synchronizes and maintains the timing and frequency requirement of power and process industry equipment using signal obtained from different external sources such as GPS, GLONASS and Galileo. It provides nanosecond accuracy when external time references are not available. It has the storage facility to store the system log file. It delivers NTP, SNTP, IRIG-B, PFC-Pulse, RS232 & RS485 outputs. System enables configuration and monitoring through Web-based application. It supports wide range of power supply input either 90V-260V AC/DC or 18-36VDC or 36V-72VDC.
