Littelfuse, Inc. Relays, Contactors & Transformers - Single-Function & Control Relays - Time-Delay Relays - Delay-on-Break - Series: HRDB - HRDB21A65M HRDB21A65M

Description
The HRDB Series combines an electromechanical, relay output with microcontroller timing circuitry. The HRDB offers 12 to 230V operation in five options 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 (Delay-on-Break)Inpu t 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.
