Honeywell M7284C1000 Motor

The Honeywell M7284C1000 is a high-torque, non-spring return Modutrol IV Motor designed for precise proportional positioning of dampers and valves in commercial HVACR and burner systems. Operating on a 120V supply, this heavy-duty actuator responds to a 4-20mA control signal, making it a standard choice for modulating fuel/air ratios or regulating airflow in large-scale air handling units. This model replaces several legacy series, including the M744 and M745, and is functionally identical to the M7284C1000/U. It delivers a robust 150 lb-in torque rating and features a field-adjustable stroke from 90 to 160 degrees, allowing technicians to match the travel precisely to the specific linkage geometry of the application. The die-cast aluminum housing includes an integral junction box providing NEMA 3 weather protection, ensuring reliable performance in demanding mechanical environments.

For contractors conducting a Honeywell M7284C1000 replacement, this motor features a dual-ended 3/8-inch square shaft and two internal auxiliary switches for proof-of-position or sequencing interlocking. For complex damper actuator setups, the 4-20mA 120V motor ensures stable modulation without the drift common in lower-specification actuators.

• High Torque Output: Provides 150 lb-in of torque to handle heavy-duty butterfly valves and dampers.
• Flexible Stroke Adjustment: Field-adjustable from 90° to 160° to accommodate various mechanical linkages.
• Dual-Ended Shaft: Simplifies installation by allowing mounting on either side for improved access.
• NEMA 3 Rated: Weather-resistant aluminum housing protects internal components in upright mounting positions.
• Integrated Auxiliary Switches: Includes two internal switches for position feedback and burner sequencing.

Common Questions

Is the M7284C1000 a spring-return motor?
No, this is a non-spring return (NSR) motor. It will maintain its last commanded position upon a loss of power rather than returning to a default "closed" or "open" state.

Can I use this motor to replace an older Honeywell Modutrol motor?
Yes, the M7284C1000 is the modern replacement for several older models, including M744S, T, Y and M745S, T, Y. It uses the standard Modutrol IV footprint for easy retrofitting.

How do I adjust the stroke on this actuator?
The stroke is adjustable between 90 and 160 degrees via internal cams. This allows you to calibrate the rotation to match the full travel of the valve or damper you are controlling.
