Description
Honeywell M9184C1031 Modutrol IV Series 90 Motor
The Honeywell M9184C1031 is a 24 VAC Modutrol IV Series 90 proportional motor designed to position dampers and valves in commercial HVAC, boiler, burner and industrial control applications.
The M9184C1031 uses a 135-ohm Series 90 proportional control signal, provides 150 lb-in of torque, and features non-spring return operation with two factory-installed internal auxiliary switches.

135-Ohm Series 90 Proportional Control
The Honeywell M9184C1031 is designed for controllers that provide a Series 90 135-ohm proportional output.
The actuator modulates its shaft position in response to the control signal, allowing precise positioning of compatible dampers and valves.
150 lb-in Torque
The M9184C1031 provides 150 lb-in of torque, making it suitable for larger dampers, valves and other commercial or industrial control applications requiring higher actuator torque.
Non-Spring Return Operation
The M9184C1031 is a non-spring return actuator.
Unlike a spring-return motor, it does not automatically drive to a predetermined fail-safe position when power is removed. Always confirm the required fail-position behavior before replacing an existing actuator.
Two Internal Auxiliary Switches
This model includes two factory-installed adjustable auxiliary switches.
These switches can be used for functions such as:
- Equipment interlocks
- Position indication
- Alarms
- Burner sequencing
- Auxiliary control circuits
Adjustable Stroke
The M9184C1031 has a field-adjustable stroke from 90° to 160°, with a factory setting of 90°.
This allows the motor travel to be matched to the requirements of the connected valve or damper.
Typical Applications
The Honeywell M9184C1031 is commonly used to position:
- HVAC dampers
- Combustion-air dampers
- Control valves
- Boiler controls
- Burner systems
- Air-handling equipment
- Industrial process-control equipment
M9184C1031 vs. M9184A1019
Both models are 24V Modutrol IV Series 90 motors with 150 lb-in torque and 135-ohm proportional control.
The key difference is auxiliary switches:
M9184C1031
- 2 internal auxiliary switches
M9184A1019
- 1 internal auxiliary switch
Always verify auxiliary-switch requirements before substituting one model for another.
Does M9184C1031 Replace CB 894-3481?
The Honeywell M9184C1031 is commonly cross-referenced as a replacement for CB 894-3481.
Verify shaft, linkage, voltage, control signal and application requirements before replacing a legacy actuator.
