The NATIONAL TIME DU Series Digital Clock/Timer offers operation and features beyond those found throughout the industry. This microprocessor based unit functions as a 6- digit 24 hour count up timer as well as a secondary clock with the intelligence to adapt to the master clock system on which it is installed. Whether it is a 3-wire synchronous system with 58th minute correction or hourly correction, a 4-wire system with AC run and DC reset, or a two wire system with actual time reset, right out of the box this clock can distinguish and accept the most popular reset formats. For those legacy reset formats, they can be selected from an always growing list of supported formats. This premium series also offers NATSCO's exclusive automatic dim feature that decreases the brightness to compensate for low ambient light levels useful in today's high-tech surgical suites. Nine brightness levels may be selected to satisfy the brightest locations. 12 hour or 24 hour time format is selectable at each clock as well as 50/60hz for accurate timekeeping. Heavy duty, positive-action switches on a stainless steel single-gang plate provide remote timer controls up to 50' away. Stand-alone operation without a master clock is also made possible using the remote timer switches (order separately model DU-ET-CTRL). 24VAC units are available in attractive 4" or 2.25" high visibility, wide-bar digits. Digits are epoxy filled and sealed to provide the longevity you have come to expect from National Time and Signal. Compatible with 120VAC powered systems or stand-alone using local power when the appropriate 24VAC transformer is mounted at each clock or double face unit. The durable steel housing, plug-in connectors and universal mounting plate simplify installation. An optional low profile surface box allows for surface mounted conduit entry. Powder grey finish standard, other colors upon request. [Product Specs]
