Honeywell M7284C1000 Modutrol IV Actuator – 120V, 150 lb-in, 4–20 mA Control, Non-Spring Return, Foot-Mounted

Honeywell M7284C1000 Non-Spring Return Actuator

The Honeywell M7284C1000 is a high-performance Modutrol IV Series 72 electric actuator designed for precise positioning of dampers and valves in commercial and industrial HVAC systems. This non-spring return actuator accepts a modulating 4–20 mA control signal from an electronic controller and positions the connected device anywhere between fully open and fully closed.

Key Features:

• Modulating Proportional Control (4–20 mA):
  Interfaces with electronic controllers that output a 4 to 20 mA signal, enabling smooth and precise positioning across the full stroke range.

• 120 VAC Operation:
  Powered by standard 120 Volt AC, making it compatible with most building power systems without the need for additional transformers.

• Non-Spring Return Design:
  Holds its last position upon power loss, ideal for applications where retaining damper or valve position is critical during a power interruption.

• 150 lb-in Torque Output:
  Provides consistent and reliable 150 lb-in of torque, suitable for large or high-load dampers and valve actuators.

• Dual Shaft Design:
  Features dual-ended square shafts (.375” slotted and tapped on both ends), offering installation flexibility and compatibility with a wide variety of linkages.

• Adjustable Stroke Range:
  Field-adjustable stroke between 90° and 160° (asymmetrical), providing adaptability for different valve/damper travel needs.

• Two Internal Auxiliary Switches:
  Includes 2 factory-installed auxiliary switches with field-adjustable cams—ideal for signaling or sequencing other control equipment.

• Quick Connect and Screw Terminals:
  Comes standard with quick-connect terminals, with a screw terminal adapter available for installations preferring traditional wiring methods.

• Durable Construction:
  Housed in a rugged die-cast aluminum enclosure for long-term durability and resistance to mechanical stress.

• Weather-Resistant Design:
  An integral junction box provides NEMA 3 weather protection when mounted upright—suitable for sheltered outdoor or high-moisture indoor environments.

• Universal Mounting & Retrofit Ready:
  Foot-mounted design includes adapter brackets for matching shaft height to older motors, simplifying retrofit projects.
