- Isolated, 30A, SPDT, NO Output Contacts
- 12 to 230V Operation in 5 Options
- Delays from 0.1s‑100m in 5 Ranges
- 0.5% Repeat Timing Accuracy
- Factory Fixed, Onboard or External Adjust
The HRD9 Series combines an electromechanical relay output with microcontroller timing circuitry. It offers 12 to 230V 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 HRD9 is ideal for OEM applications where cost is a factor.
Operation (Motion Detector/Retriggerable Single Shot): Input voltage must be applied prior to and during timing. The output is de‑energized. Upon closure of the initiate switch (momentary or maintained) the output energizes and the time delay starts. On completion of the delay period, the output de‑energizes. Reset: Reclosing the initiate switch during or after timing will reset the time delay and restart timing. Reset is also accomplished by removing and reapplying input voltage. Note: Powering up the unit with the initiate switch closed will not energize the output relay or start timing.
