Description

The HRDR Series combines an electromechanical relay and

microcontroller timing circuitry. It offers 12 to 230V operation in

five ranges and factory fixed, onboard or externally adjustable

time delays with a repeat accuracy of ±0.5. The high switching

capacity of the output contacts allow for direct control of heavy

loads like compressors, pumps, motors, heaters and lighting. A

bypass/reset switch option allows operator to interrupt normal

recycling sequence and energize output relay. An excellent

choice for OEM applications.

Operation (Recycling with Reset Switch)

Upon application of input voltage, the ON time T1 begins and

output relay energizes. At the end of the ON time, the output

relay de-energizes and the OFF time T2 begins. At the end of the

OFF time, the output relay energizes and the cycle repeats as

long as input voltage is applied. Some recycling timers have the

OFF time as the first delay.

Reset: Removing input voltage resets output and time delays,

and returns sequence to the first delay.

Bypass/Reset Switch: Closing the normally open bypass/reset

switch energizes the output relay and resets the time delays.

Opening the switch restarts recycling operation with the

first delay.
