Description
The Honeywell M9184D1021 is a non‑spring‑return, modulating Modutrol IV motor engineered for proportional control in advanced HVAC systems. Operating on a Series 90 (135 Ω) control signal with 24 VAC input, this robust actuator delivers 150 lb‑in of torque and a 90°–160° adjustable stroke, typically set at 160°. It’s a direct replacement for legacy models like M9184A/B and provides reliable, high-performance control of dampers and valves.
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.
