Belimo SF24A-SR

Rotary actuator with safety function designed to control dampers in technical building systems. According to the technical data sheet, it is intended for air dampers with an area of up to approx. 4 m². The Y control signal moves the damper to the operating position and simultaneously tensions the return spring. When the power supply is interrupted, the spring moves it to the safety position.
