          Series Features
    Motion Detector HRD9 Power-Time Time Delay Relay
    Series Description: The HRD9 Series combines an electromechanical relay output with digital timing circuitry. 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: 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 is energized and the time delay is started. On completion of the delay period, the output is de-energized.
    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 unit with initiate closed will not cause the output relay to energize.
    • 15 A (UL)/30 A (CSA) Isolated Output Contacts
    • 12 ... 230 V Operation in 5 Ranges
    • Delays from 200 ms ... 100 m
    • Digital Timing Accuracy
    • Fixed, Remote or Onboard Adjustment
