HRD9 Power-Time
Time Delay Relay
Description
The HRD9 Series combines an electromechanical relay output with microcontroller timing circuitry. It offers
12 to 230 V operation in ve ranges and factory xed, 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 HRD9 is ideal for OEM applications where
cost is a factor.

Operation
Input voltage must be applied prior to and during
timing. The output is de-energized. Upon closure
of the initiate switch (momentary or maintained)
the output energizes and the time delay starts.
On completion of the delay period, the output deenergizes.
Reset: Reclosing the initiate switch during or after
timing will reset the time delay and restart timing.
Reset is also accomplished by removing and
reapplying input voltage.
Note: Powering up the unit with the initiate switch
closed will not energize the output relay or start
timing.
