Rotary Drive Synchronous (RDS)

RDS Analog Clocks

The industry's most advanced analog clock. The RDS incorporates state-of-the-art microprocessing with infrared positioning sensing creating the most accurate timekeeping system. A powerful rotary stepper motor and indexing technology not only makes this the most durable mechanism, but it also has the lowest power consumption. Less than 10 cents per year! On-demand instant reset capability gets your clocks on time when you need it... now! An industry exclusive.

Rotary Drive Synchronous (RDS)

Spectrum Clocks

The Spectrum Series analog clock operates on a wide range of wired clock system types. From historical 3-wire synchronous systems to 2-wire midnight resets to 2-wire On-Demand reset systems, from 24V to 120V -- the Spectrum Series has it covered. The energy efficient design uses less power than previous systems allowing longer wire distances with less power supplies. An on-board microprocessor monitors the hand position to ensure accurate time display and does not require any user intervention to re-calibrate the hand location like clocks by others.
