Description
The Honeywell M9174B1027 is a rugged, foot-mounted Modutrol IV actuator featuring a non-spring return, proportional control action. Designed to operate dampers or valves using a 135 Ω control signal, this actuator delivers precise modulation in zoning systems, energy recovery units, VAV boxes, and hydronic loops.
Features:
- Integral junction box provides NEMA 3 weather protection if motor is mounted in the upright position.
- Motor and circuitry operate from 24 Vac.
- Quick-connect terminals are standard–screw terminal adapter is available.
- Adapter bracket for matching shaft height of older motors is available.
- Motors have field adjustable stroke (90 to 160 degrees).
- Integral auxiliary switches are available factory mounted, or can be field added.
- All models have dual shafts (slotted and tapped on both ends).
- All models have auxiliary switch cams.
- Fixed torque throughout the entire voltage range.
