Master Clocks > Products > Master Clock Systems

Four circuits (standard) to control any combination of clocks or auxiliary outputs.  Dry contact relay outputs. Add up to 12 circuits with EXP-4 expansion modules.  GPS time accuracy available with the MC100-GPS antenna.  Add LAN programming and NIST timebase with the WeM-MC100 adapter.

The MC100WP is the weather proof version of the MC100.  Four output circuits can control any combination of clocks or auxiliary outputs such as lights or bells.  Add GPS time accuracy with the MC100-GPS antenna.

The MC100WP is the rack mount version of the MC100.  Four output circuits are standard and can be expanded to eight circuits with one EXP-4 expansion module.  The dry-contact outputs can control any combination of clocks or auxiliary outputs such as lights or bells.  Add GPS time accuracy with the MC100-GPS antenna.  Add LAN programming and NIST timebase with the WeM-MC100 adapter.

The MC3 is the most cost effective solution for accurate control of National clocks or clocks by other manufacturers.  Three 120VAC solid state outputs can control multiple clock circuits simultaneously.  Battery-less backup provides time keeping for over 3 months during outages.  Automatic daylight savings and power outage adjustments.  Add GPS time accuracy with the MC3-GPS antenna.

The Web Enabled MC3 is the industry's best value for a LAN programmable Master Clock.  Three 120VAC solid state outputs can control clock circuits or auxiliary outputs such as tones, bells, lights etc.  Highly visible LED display and keypad can be used during setup to get clocks running before the LAN is installed.   Programming can be accomplished using a web browser from any PC on the network or internet.

The Web Enabled Network Controller is a LAN programmable Master Clock.  Synchronize the time with your local LAN or NIST over the internet.  Two 120VAC solid state outputs can control clock circuits or auxiliary outputs such as tones, bells, lights etc.  Programming is accomplished using a web browser from any PC on the network or internet.

These GPS antennas can keep your architectural clock accurate to the time kept by the National Institute of Standards and Technology (NIST).   The antenna communicates to the master clocks using serial data communications eliminating expensive antenna cable extensions.  Comes standard with a 30' cable, but can be extended if necessary.

Add LAN or NIST time synchronization to your MC100 or MC100RM.  Automatically connects to your local area network and allows programming and remote control from any PC on the network or internet using a standard web browser.
