Recycling (Flasher) 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. Function Operation (ON Time First) Equal ON and OFF Delays 30 A SPDT N.O. Output Contacts 12 ... 230 V Operation in 5 Ranges Encapsulated Circuitry Delays from 100 ms ...100 m in 5 Ranges +/-0.5% Repeat Accuracy Fixed, External, or Onboard Adjustment Approvals: 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. Recycling (ON First) Recycling (OFF First) 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.
