Information About M9484E1033
The M9484E1033 is a Honeywell Modutrol IV Series 90 motor engineered for proportional control in commercial and industrial oil or gas burner systems. It operates as a non-spring return motor and is regulated by a three-wire proportional controller, allowing smooth and accurate positioning. The motor features a field-adjustable stroke of either 90 or 160 degrees and includes an internal auxiliary switch for control sequencing or indication. It is electrically driven, vibration resistant, and designed as a direct replacement for legacy Honeywell M941A, M941C, and M941D motors.
Key Features
- Proportional Series 90 Control: Provides smooth, continuous modulation when used with compatible proportional controllers.
- Adjustable Stroke Range: Field-selectable 90° or 160° stroke supports flexible burner and damper configurations.
- High Torque Output: Delivers 150 lb-in running torque with 300 lb-in breakaway torque for demanding applications.
- Non-Spring Return Design: Maintains commanded position during normal operation without spring bias.
- Integrated Auxiliary Switch: Includes one internal switch with precise 7-degree setting for sequencing functions.
- Durable Mechanical Construction: Double-ended square shaft supports direct coupling to valves and dampers.
- Wide Temperature Capability: Operates reliably from -40°F to +150°F in industrial environments.
The M9484E1033 delivers the reliability and precision required for accurate firing rate control in commercial and industrial burner systems.
