The WeMC3 Master Clock is a powerful master clock with the programming ease of a web interface. The WeMC3 comes standard with three solid state 120VAC outputs to directly control clock circuits or auxiliary outputs without the need for additional relays. These solid state outputs are capable of driving up to 3 amps each (7 amps combined) and incorporate zero-cross technology to handle undesirable current surges and inrush.

The WeMC3 provides web-based based configuration and programming. The user-friendly interface is used to create and edit programmed event schedules for auxiliary devices. Without requiring special software to be installed, the programming can be accomplished from any PC on the network with a standard web browser. Programming can even be done from a remote location to allow district or city-wide scheduling control.

The WeMC3 and secondary clocks combine to create a maintenance-free time system automatically synchronizing the clocks over the internet to the National Institute of Standards and Technology (NIST) for the most accurate time keeping. Alternately, a local network time server or any PC can be used to keep the clocks and auxiliary events perfectly synchronized with the computer network time. All clocks can be automatically adjusted for daylight savings adjustments and power outages. When there is a power loss, the WeMC3 can keep time internally for over 150 days without the need for batteries or expensive rechargeable battery packs. The WeMC3 can correct the complete line of National Time clocks as well as clock systems by other manufacturers. The WeMC3 can even transmit National Time’s On-demand Instant Reset to new clocks over the clock system wiring without affecting the existing clocks. The WeMC3 can also synchronize time with a sound system, paging system, phone system, media retrieval system or an existing master clock with a synchronizing output.
