The Honeywell CS4110A1200 is a high-performance spring return direct-coupled damper actuator, engineered for precise and reliable control in commercial HVAC and building automation systems. Operating on a wide 100-250V AC power supply, this 10Nm actuator delivers consistent torque for on/off control of air dampers in ventilation, air handling, and heating systems.

 

Its spring return mechanism ensures fail-safe operation, automatically returning the damper to a safe position during power loss or system failure, meeting critical safety requirements for commercial buildings and fire ventilation systems. The self-centering shaft adapter accommodates various standard damper shaft sizes, eliminating the need for adapters or linkages and simplifying installation.

 

Equipped with adjustable mechanical travel limits (in 5° increments) and a manual override with locking function, it allows for flexible commissioning and emergency operation. Built to withstand temperatures from -40°F to 140°F (-40°C to 60°C) with an IP54 rating, it delivers reliable performance in diverse indoor environments.

 

Suitable for office buildings, hospitals, data centers, industrial facilities, and other commercial HVAC applications, the CS4110A1200 is a premium replacement actuator for maintenance, system retrofitting, and new installations, ensuring energy efficiency, indoor air quality, and system safety.
