Honeywell M7284A1004

New Honeywell M7284A 1004 Series 72 Modutrol IV™ Motor

The Series 72 Modutrol IV™ Motors are designed primarily for precision control of dampers and valves. These motors are integral to HVAC systems, where they modulate the position of dampers and valves based on signals received from primary controllers. This modulation ensures that the dampers or valves can be adjusted to any position between fully open and fully closed, optimizing airflow and fluid control within the system.

Here is how they work:

• Signal Reception: These motors interpret current or voltage signals from the connected primary controller.
• Accurate Positioning: Based on the signals, the motors adjust the damper or valve position to precise angles.
• Enhanced Control: This allows for fine-tuned regulation of environmental conditions, making your HVAC system more efficient and responsive.

The Series 72 Modutrol IV Motors are essential for achieving precise control in HVAC applications, improving overall system performance and energy efficiency.

With nominal timing of 30 to 60 seconds, and a field-adjustible rotation from 90° to 160°, this model is a direct replacement for M7284A1046 and M7281A1007.

For added versatility, the Series 72 Modutrol IV™ Motor features a dual-shaft design—slotted and tapped on both ends—to simplify installation and ensure compatibility with a wide range of damper and valve linkages. An adapter bracket is available to match shaft height for older motors, making upgrades straightforward.

Field-adjustable stroke (90° to 160°) lets you fine-tune operation to suit your specific application. The motor delivers consistent, fixed torque across its entire voltage range, so you can count on reliable control performance. Models are designed for both normally open and normally closed dampers and valves, with options for adjustable start (zero) and span to further enhance flexibility.

Integral auxiliary switch cams come standard, and you can factory order or field add auxiliary switches as needed for your setup. Input signal options include 4 to 20 mA and 2 to 10 Vdc, supporting integration with a broad variety of control systems.

Whether you’re retrofitting an existing system or installing new, these features help ensure the right fit and smooth operation for demanding HVAC applications.
