Delay On Make (Operate) HRDM Power-Time Time Delay Relay Description The HRDM 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 30 A SPDT N.O. Output Contact 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: Function Upon application of input voltage, the time delay begins. The output is de-energized before and during the time delay. At the end of the time delay, the output relay energizes and remains energized until input voltage is removed. Reset: Removing input voltage resets the time delay and output.
