DC-Digital "Made to order" LED Timers, Counters, Clocks and Number Displays

DC-digital Industry Drive

    DC-Digital (Division of I.E.S.); We are a Christian based veteran co-owned Digital LED timers, counters, time of day clocks and number displays manufacturer.
    Originated in 1996 out of the need to satisfy our local schools with an economical but reliable and accurate classroom clock and class change bell system. We developed, patented and manufactured the 2-wire DC power and correction clock system (power and data presented to the clock on the same 2 wires). We were finding that (through servicing the school's other clock systems) was that the schools had already had at least 2 wires in each classroom dedicated for this purpose. The 2-wire method captured the already available 2 wires allowing the installer quick, simple installation and easy serviceability, which in turn lead to significant cost savings for the schools. Popularity of the design and our company spread quickly and lead to many subsequent display designs, now with over 800 different variations of clocks, timers, counters, and number displays. We have a full staff of engineers (software and hardware), assemblers,  technicians, marketing, machinists, sales, and administration that can handle any of your number display needs. We combine specific input and output hardware to match our base model electronics and displays to achieve maximum visual awareness that will gratify all of your needs and expectations. Today everything is still hand made in house, to each order giving us total manufacturing control making us extremely flexible to provide you with the proper displays that will fit your application. Don't hesitate to contact us today!
