HRDS Power-Time
Time Delay Relay
Description
The HRDS 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 output contact rating allows for direct operation of heavy loads such as
compressors, pumps, blower motors, heaters, etc. This series is ideal for OEM applications where cost is
a factor.
Operation
Input voltage must be applied before and during timing.
Upon momentary or maintained closure of the initiate
switch, the output relay energizes for a measured
interval of time. At the end of the delay, the output
de-energizes. Opening or reclosing the initiate switch
during timing has no affect on the time delay. The
output will energize if the initiate switch is closed when
input voltage is applied.
Reset: Reset occurs when the time delay is complete
and the initiate switch is opened. Loss of input voltage
resets the time delay and output.
