Delay On Break (Release) HRDB Power-Time Time Delay Relay Description The HRDB Series combines an electromechanical relay output with microcontroller timing circuitry. The HRDB 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 isolated output contact rating allows for direct operation of heavy loads such as compressors, pumps, blower motors, heaters, etc. The HRDB is ideal for OEM applications where cost is a factor. Operation 30 A SPDT N.O. Isolated Output Contacts 12 ... 230 V Operation in 5 Ranges Delays from 100 ms ...100 m in 5 Ranges +/-0.5% Repeat Accuracy Fixed, External, or Onboard Adjustment Function Input voltage must be applied before and during timing. Upon closure of the initiate switch, the output relay energizes. The time delay begins when the initiate switch is opened. The output remains energized during timing. At the end of the time delay, the output de-energizes. The output will energize if the initiate switch is closed when input voltage is applied. Reset: Reclosing the initiate switch during timing resets the time delay. Loss of input voltage resets the time delay and output.
