Honeywell MS8120F1200 24V Two Position Spring Return Actuator 175 lb-in

The Honeywell MS8120F1200 is a fast-acting, direct-coupled damper actuator designed for commercial HVAC applications requiring reliable two-position control. This 24-volt spring return actuator delivers 175 lb-in of torque, making it suitable for controlling medium to large dampers in air handling systems, rooftop units, and ventilation equipment.

Key Features:

• Two-position control with spring return to normally closed or normally open position
• 175 lb-in (20 Nm) torque output for demanding damper applications
• Fast-acting operation for quick response times
• Direct-coupled mounting eliminates linkages for reliable installation
• 24VAC/DC power supply for standard HVAC control compatibility
• Durable construction designed for commercial building automation systems
• Auxiliary switches for position indication and control integration

This actuator is ideal for freeze protection, smoke control, economizer dampers, and other applications where positive spring return action is required for safety or energy management. The direct-coupled design simplifies installation and reduces maintenance requirements compared to linkage-based systems.
