Time Systems

Franklin Instrument’s master clocks are microprocessor/quartz crystal based time system controllers designed to drive a variety of low voltage impulse, midnight reset, sync wire, and RS232 secondary clocks. A complete line of both analog and digital secondary clocks are available.

  • Analog Secondary Clocks


    FRANKLIN MARK 4

    FRANKLIN MARK 4 analog clocks combine the reliability of a quartz movement gear train with a solid state micro-controller to achieve a low voltage energy efficient clock with multiple correction schemes.

    ECONOMICS:

    • Affordable initial acquisition cost.
    • Reduced power consumption
    • Low voltage plenum cable
    • 24 volt models require no conduit
    • Mounts to a standard one-gang electrical box, no need for special back boxes or mounting hardware.

    ENGINEERS SPECIFICATIONS:
    MARK 4 secondary clocks are compatible with popular master clock systems using a 3-wire synchronous scheme. Connect to a power source and master clock and the MARK 4 will automatically correct it’s minute and second hands each hour and perform a full 12-hour correction twice daily. Errors due to power failures and Daylight Saving Time are automatically adjusted.
