Master Clock QCG-200
Master Clock Benefits
■QCG-200 is a master clock
which is capable of receiving the precise time information from GPS
(Global Positioning System) operated by the U.S. and can retain a
high-accuracy in the internal clock at all times.
■Exclusive GPS antenna with receiver unit (GPS-200) is available
separately to make a time correction for the internal clock in the
QCG-200 periodically.
■QCG-200 is capable of making analog secondary clocks activate directly and synchronizing them with a precise time.
■QCG-200 is capable of generating time data (in accordance with RS-422) for digital secondary clocks and other computer systems.
Automatically time synchronization with GPS( Global Positioning System).
・Time Accuracy when synchronized by GPS signal is within ±5ms.
・Exclusive GPS antenna with receiver unit can be purchased separately.
・High-accuracy crystal clock inside(Accuracy daily rate : within ± 0.1s)
・Rack mounting type complied with EIA(Electronic Industries Alliance) Standard
・Maximum 110pcs. of secondary clocks can be activated.
・Both Two hands and Three hands secondary clocks can be activated.
・Serial data signal output(RS422) is available to synchronize Digital Clocks and so on.
・Liquid Crystal Display(LCD) with dimmer function for monitor clock in 3 steps(off-mid-hi)
・Daylight saving time and leap time can be set by key input.
・Time adjustable with Time Server(SNTP) through LAN(RJ45) as an option
