Variations

  • ETMC-2W

    Our next generation technology eliminates the complexity and high cost of today’s PoE approach and delivers the simplest, most affordable and greenest answer to reliable, precise time throughout your facility, your campus or your worldwide operations. Wall mount and rack mount versions available.

  • ETMC-3W

    Simply plug into a local area network (LAN) and a power outlet to install. Class II power limited outputs can control a conventional 3-wire clock system. Synchronize the time with the National Institute of Standards and Technology (NIST) or local time servers using the LAN. One relay output is available for auxiliary event programming such as bells or tones and is easily programmable using National Time’s WeCan™ browser based interface from any computer.

  • ET-RPS6 Power Supplies

    Add additional power to the ET Series Master Clock with these Remote Power Supplies. Available in wall mount and rack mount and simply plug into a standard power outlet. These can also be used to extend a National Time conventional 2-wire clock system of DLU and RDS clocks or the 3-wire version can be used with conventional synchronous systems by National Time or others.
