SSAC HRPU Series, HRIU Series Data Sheet
HRPU / HRIU SeriesTimer
L1 N/L2
Connection:
HRIU
Isolated Output
The HRPU/HRIU Series combines an
electromechanical relay output with
microcontroller timing circuitry. Its switching
capacity allows direct control of loads like
compressors, pumps, motors, heaters, and
lighting. It is a factory programmed module
available in any 1 of 14 standard functions. The
HRPU/HRIU offers a single adjustable timer
or counter function. Switch adjustment allows
accurate selection of the time delay or number
of counts. The HRPU has non-isolated relay
contacts, the HRIU has isolated relay contacts.
Encapsulation protects against shock, vibration,
and humidity. The HRPU/HRIU Series is a cost
effective approach for OEM applications that
require small size, reliability and accurate switch
adjustment.
See Appendix B, page 165, Figure 2 for dimensional
drawing.
