M9184C1031

Honeywell M9184C1031 Modutrol IV Series 90 Non-Spring Return Actuator, 24V

The Honeywell M9184C1031 is a Series 90 Modutrol IV proportional actuator engineered for precision control of dampers and valves in commercial and industrial HVAC systems. Designed for use with controllers that provide a 135 Ohm proportional control signal, this 24 VAC, non-spring return motor delivers smooth, accurate modulation with consistent torque across the voltage range.

Key Features:

• Proportional Control (135 Ohm):
  Designed to work with Series 90 controllers providing a 135 Ohm output for smooth, modulating control of airflow or fluid flow.

• 24V Non-Spring Return Operation:
  Maintains position upon power loss—ideal for systems where fail-positioning is not required.

• High Torque Output:
  Delivers 150 lb-in of torque consistently across the voltage range, capable of operating large or high-resistance dampers and valves.

• Adjustable Stroke:
  Field-adjustable stroke range from 90° to 160° (factory set at 90°), allowing flexibility to match a variety of damper or valve travel requirements.

• Internal Auxiliary Switches:
  Includes 2 factory-mounted auxiliary switches with cams for field adjustment—ideal for interfacing with other equipment, such as interlocks, alarms, or system feedback loops.

• Quick Connect Terminals:
  Equipped with quick-connect terminals for fast, secure electrical connections. A screw terminal adapter is also available for alternate wiring preferences.

• Dual-Ended Shaft Design:
  Features a .375” square dual-ended shaft (slotted and tapped on both ends), providing compatibility with a variety of linkage configurations and simplifying retrofit applications.

• Durable Construction with Weather Protection:
  Integral junction box provides NEMA 3-rated protection when mounted upright, offering defense against rain, sleet, and external moisture for dependable outdoor performance.

• Mounting & Retrofit Options:
  Foot-mounted design with optional adapter brackets for matching shaft height of older motor models, making retrofit and replacement projects seamless.

• Temperature & Environmental Range:
  Operates reliably in extreme environments with a wide temperature range of -40°F to 150°F, and capable of withstanding 200 lb deadweight load per shaft end (300 lb combined).
