Description
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.
