Honeywell MS8120A1205 24V Spring Return Actuator 175 lb-in Torque 2-Position Direct Coupled

The Honeywell MS8120A1205 is a 24-volt spring return damper actuator designed for commercial HVAC applications requiring reliable, direct-coupled control of dampers and valves. This robust actuator delivers 175 lb-in of torque, making it suitable for controlling medium to large dampers in air handling systems.

Key Features:

• 24VAC/DC power supply for versatile installation compatibility
• 2-position control with spring return to fail-safe position on power loss
• 175 lb-in (19.8 Nm) torque output for positive damper seating
• Direct coupled mounting eliminates linkage complications
• Spring return mechanism ensures automatic return to normal position during power failure
• Durable construction for long service life in commercial HVAC environments
• Compact design for easy installation in tight spaces

This actuator is ideal for use in economizer systems, fresh air intake dampers, exhaust dampers, and other HVAC applications where fail-safe positioning is critical. The direct coupled design provides a secure, rigid connection to damper shafts, ensuring reliable operation and eliminating the maintenance issues associated with linkage-based systems.
