Master Clock

Master Clock is control outputs for secondary clocks and independent peripheral devices. The SEIKO programmable Master Clocks not only control secondary clock precisely for synchronized time keeping, but they can also be programmed to sound a chime. Furthermore the SEIKO Master Clock can automatically turn on and off air conditioning equipment, illuminations, etc. for energy savings, and can also control crime prevention equipment for manpower savings. Use these master clocks in offices, schools, factories, stores, banks, etc.

GPS Maseter Clock SEIKO QCG-100
Master Clock Benefits
  1. QCG-100 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.
  2. Exclusive GPS antenna with receiver unit (GPS-100) is available separately to make a time correction for the internal clock in the QCG-100 periodically.
  3. QCG-100 is capable of making analog secondary clocks activate directly and synchronizing them with a precise time.
  4. QCG-100 is capable of generating time data (in accordance with RS-422) for digital secondary clocks and other computer systems.
