GPS Master Clock System – MCS-GPSMC-1010 is a 3U Card rack type, 19” Rack-mountable Redundant GPS Time Server which synchronizes and maintains the timing and frequency requirement of power and process industry equipment using a signal obtained from any one of the sources like GPS or GLONASS or NAVIC and time protocols such as NTP and IRIG. It distributing the same time signal through several types of interfaces. It provides redundancy for Power and GPS receiver to increase reliability and offers protection against time synchronization failure. The system is field-upgradeable and an extremely flexible system, designed to handle time synchronization requirements today and in the future. It provides nanosecond accuracy when external time references are not available. It has a storage facility to store the system log file. It delivers NTP, SNTP, IRIG-B, PFC-Pulse, DCF77, BCD parallel data, Ethernet Fiber Optic & RS485/RS232 outputs. System enables configuration and monitoring through Web-based application. It supports a wide range of power supply either 90V-260V AC/DC or 18-36VDC or 36V-72VDC. Power supply model can be mixed and matched as required by the user, depending upon power supply options available at the installation site.
