Honeywell M9184D1021 Motor

The Honeywell M9184D1021 Modutrol IV Motor is a high-torque, non-spring return actuator designed for precise proportional control of dampers and valves. Operating on a 24Vac power supply, it responds to a 135 Ohm control signal, making it a reliable choice for commercial combustion and HVAC systems. This proportional Honeywell actuator delivers 150 lb-in torque and features a field-adjustable stroke ranging from 90 to 160 degrees. It comes factory-set at 160 degrees for immediate installation in standard configurations. The M9184D1021 utilizes a dual-ended 3/8-inch square shaft and quick-connect terminals to streamline field wiring. Built for durability, the integral junction box provides NEMA 3 weather protection, ensuring performance in demanding environments. This motor serves as the direct replacement for Honeywell M150JGA-1, offering a seamless retrofit path for legacy Series 90 modutrol applications requiring consistent modulating motor performance and 30-60 second timing.

Key Benefits for Technicians

• High Torque Output: Rated at 150 lb-in to handle heavy-duty damper linkages and large valve assemblies without stalling.
• Versatile Application: Proportional control via 135 Ohm resistance input integrates easily with legacy Honeywell controllers.
• Field Adjustability: Adjustable stroke settings (90 to 160 degrees) allow for precise mechanical calibration on-site.
• Dual-Ended Shaft: The 0.375-inch square shaft extends from both ends, allowing for flexible mounting and linkage configurations.
• Rugged Housing: NEMA 3 rating ensures the internal components are protected against windblown dust and rain.

Common Questions

What is the best replacement for the M150JGA-1 motor?
The Honeywell M9184D1021 is the direct drop-in replacement, matching the torque, voltage, and signal requirements of the older M150JGA-1 model.

Can I adjust the stroke timing on this actuator?
The nominal timing is rated at 30 to 60 seconds for a 90-degree stroke; however, actual travel time depends on the specific stroke setting selected (up to 160 degrees).

Is this a spring return motor?
No, this is a non-spring return motor. It will maintain its last position upon loss of control signal unless otherwise configured through the controller logic.
