Description

The HRDB Series combines an electromechanical, relay output

with microcontroller timing circuitry. The HRDB offers 12 to 230V

operation in five options and factory fixed, external, or onboard

adjustable time delays with a repeat accuracy of ±0.5. The

isolated output contact rating allows for direct operation of heavy

loads, such as compressors, pumps, blower motors, heaters, etc.

The HRDB is ideal for OEM applications where cost is a factor.

Operation (Delay-on-Break)

Input voltage must be applied before and during timing. Upon

closure of the initiate switch, the output relay energizes. The

time delay begins when the initiate switch is opened. The output

remains energized during timing. At the end of the time delay,

the output de-energizes. The output will energize if the initiate

switch is closed when input voltage is applied.

Reset: Reclosing the initiate switch during timing resets the time

delay. Loss of input voltage resets the time delay and output.
