GPS TIME SYNC UNIT MC-1-DE has been developed to address key power and
process industry timing requirements. Whether it’s the monitor, control or analysis of the power sys-
tem, the GPS TIME SYNC UNIT MC-1-DE is the cost-effective GPS time synchronization solution.
To begin with, the GPS TIME SYNC UNIT MC-1-DE offers superb timing accuracy using GPS satel-
lites; it generates extremely accurate output pulses and time codes in multiple formats. It’s necessary
every time to Lock GPS once after power ON in order to ensure the better accuracy.
The GPS TIME SYNC UNIT MC-1-DE synchronizes a wide variety of microprocessor-based power
system equipment including SCADA systems, remote terminal units (RTUs), protection relays, and
sequence of event recorders, digital fault recorders, tariff meters, Slave Display Units, Data Loggers
and other Intelligent Electronic Devices (IEDs) .Each Output can feed directly to different areas
through electrically isolated ports which ensure reliable operation in a Harsh substation environment.
Being a Field programmable device using HyperTerminal, a very common application in Windows,
the GPS TIME SYNC UNIT MC-1-DE allows the user to alter the settings or choose from Time codes.
The serial port (RS232/RS485 Factory configurable) is provided for that purpose. Each output can
feed directly to different areas through electrically isolated ports which ensure reliable operation in a
harsh substation environment.
The GPS TIME SYNC UNIT MC-1-DE generates a wide range of timing signals. Standard configura-
tions of GPS TIME SYNC UNIT MC-1-DE is equipped with one serial ports, a 1PPS Port, 2 IRIG-B
TTL /AM, TWO RJ-45 NTP terminal and Two relay outputs for WATCHDOG, GPS Lock alarm and
Two additional PMOS relay based pulse outputs each configurable from a second to a day period
time, IRIG-B127 or IEEE 1344/C37.118-2005 Amplitude modulated output, Serial Port is configurable
for NMEA 0183, NGTS, and T- Format. Time synchronization protocol (NTP) standard as Server
mode implemented in GPS TIME SYNC UNIT MC-1-DE to provide time synchronization to different
slaves supporting NTP protocols (NTP v3, SNTP).
All GPS TIME SYNC UNIT MC-1-DE unit gives both installation teams and users visual feedback
about the time data being generated on the outputs. LED indicators provide “at a glance” status in-
formation.
The optimized Receiver/Antenna system employed in the GPS TIME SYNC UNIT MC-1-DE provides
time information from the GPS satellite constellation. Dynamic T-RAIM processing is used to elimi-
nate any aberrant satellite signals from the timing solution. The result is timing precision on all outputs
with accuracy similar to that normally seen only in laboratory instruments.
