DC-Digital Network and GPS Disciplined Master Clocks & Bell Ringers

DC-Digital manufactures commercial-grade synchronized clock systems tailored to your facility's exact needs. Made proudly in the USA, our atomic master clocks utilize GPS or network NTP synchronization to deliver worry-free, absolute accuracy. Easily connect an infinite number of wireless secondary clocks or wired secondary clocks through our simple setup.

We offer two distinct master clock configurations depending on your operational requirements:

  • Time-of-Day (only) Master Clocks: Engineered strictly for precise time-of-day synchronization across all wireless or wired secondary clocks.
  • Time of Day Master Clocks with Relay Closures: Features the same exact time synchronization, plus integrated relay outputs to automate school bells, manufacturing shift changes, and factory horns.

Whether utilizing your existing 2-wire setup (U.S. patent #: 5,425,004) or scaling infinitely with our wireless store-and-forward technology, DC-Digital makes facility-wide synchronization effortless.

Explore our Secondary Digital Clocks-Wireless or Secondary Digital clocks-Wired. All USA made. Contact our team to find the right system for your building. Contact us!
