Honeywell M7284A1004 Modutrol Motor

The Honeywell M7284A1004 Modutrol Motor is part of the Series 72 Modutrol IV Motors, designed for precise control of dampers and valves. This 120V non-spring return motor delivers a torque of 150 lb-in with an adjustable stroke ranging from 90° to 160°. It responds to a 4-20 mA control signal, ensuring accurate modulating control. The foot-mounted design facilitates easy installation and integration into HVAC systems. Ideal for applications requiring precise positioning of dampers or valves, the M7284A1004 provides reliable performance and flexibility in various control scenarios.
