Rotary Drive Impulse (RDI)

Rotary Drive Impulse (RDI)

There has never been an impulse clock like this! National Time, the modern-day founder of impulse clock systems, has been manufacturing impulse clocks since 1870!  The RDI clock combines this experience with today's technology to create an impulse clock system like no other.  A powerful Rotary drive stepper motor, infrared position sensors, and microprocessor technology are brought together to make the most accurate time system. Unlike any other impulse system, power and data are transmitted on the same wires allowing an industry exclusive On-Demand Instant Reset.  These intelligent school clocks can also operate on existing 2-wire or 3-wire systems.
