Description
Honeywell M4185B1009 Modutrol IV Spring Return Motor
The Honeywell M4185B1009 is a 120V Modutrol IV two-position spring-return motor designed for controlling dampers and valves in HVAC, combustion and industrial control applications.
The M4185B1009 provides 60 lb-in of torque and uses SPST two-position control. Its spring-return design returns the connected damper or valve to its normal position if power is interrupted.
This model also includes one internal auxiliary switch and an internal transformer.

Applications
The Honeywell M4185B1009 Modutrol IV motor is designed for two-position operation of compatible:
- Air dampers
- Control valves
- HVAC equipment
- Boiler and burner systems
- Commercial and industrial air-handling equipment
- Combustion-control systems
The spring-return mechanism is especially useful in applications where the damper or valve must return to its starting position during a power failure.
Why Use the M4185B1009?
The M4185B1009 combines 120V operation, 60 lb-in torque, spring return and an internal auxiliary switch in Honeywell's proven Modutrol IV actuator platform.
When replacing an existing Modutrol motor, verify the model number, voltage, torque, control signal, shaft rotation and auxiliary-switch requirements before ordering.
