HRD3 Power-Time
Time Delay Relay

Description

The HRD3 Series combines an electromechanical relay output with microcontroller timing circuitry. It offers 12
to 230 V operation in five ranges and factory fixed, 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 (ON Time First)

Upon application of input voltage, the output relay
energizes and the T1 ON time begins. At the end of
the ON time, the output de-energizes and the T2 OFF
time begins. At the end of the OFF time, the output
relay energizes and the cycle repeats as long as input
voltage is applied.
Reset: Removing input voltage resets the output and
time delays, and returns the sequence to the first
delay.

Operation (OFF Time First)

Upon application of input voltage, the T2, OFF time
begins. At the end of the OFF time, the T1, ON time
begins and the load energizes. At the end of the ON
time the load de-energizes, and the cycle repeats
until input voltage is removed.
Reset: Removing input voltage resets the output and
the sequence to the OFF time.
