Description
The Honeywell M6284F1078-F is a heavy-duty Modutrol IV actuator motor engineered for precise, reliable control of commercial HVAC dampers and valves. Featuring a linear 10K feedback potentiometer, this motor delivers accurate position reporting to building automation and control systems. Its robust 150 lb-in torque output makes it well-suited for demanding commercial and industrial applications.
Key Features
- Modutrol IV series actuator motor with linear 10K ohm feedback potentiometer for accurate position sensing
- 24Vac operating voltage for compatibility with standard commercial control systems
- 150 lb-in torque output for reliable actuation of large dampers and valves
- Non-spring-return design — maintains last position on power loss
- 30/53 second nominal timing for controlled, smooth actuation speed
- Dual-ended square shaft for versatile mounting and direct-drive applications
- 2 internal auxiliary switches for status feedback or sequential control integration
- 90–160 degree stroke range for flexible damper and valve positioning
- Foot-mounted configuration for secure, stable installation
- Wide ambient temperature rating: –40°F to 150°F (–40°C to 66°C) for use in harsh environments
