Honeywell MS8103F1025/U

The F&S 250F rotary actuator operates at a supply voltage of 24V AC and is suitable for applications involving dampers, particularly in fire and smoke control systems. With a maximum return timing of 25 seconds and a torque rating of 27 in·lb (3 Nm), this actuator ensures reliable operation under various conditions.

Its design includes a universal shaft mounting capability and an adjustable built-in rotation limiter that allows for precise control in 7.5° increments. The actuator supports a range of environmental conditions, with a minimum operating ambient temperature of 14 °F (-10 °C) and a maximum of 150 °F (65 °C). The device also meets several regulatory standards, including UL60730 and IEC 60730, ensuring compliance for safety and performance.

Constructed from plenum-rated plastic, the actuator has an IP54 rating, making it suitable for installation in environments with potential dust and moisture. The overall dimensions are 3.266 in (83 mm) in width, 7.5 in (191 mm) in height, and 3.11 in (79 mm) in depth. Additionally, the actuator is equipped with a clip-in conduit connector and a U-bolt adapter for ease of installation.
