Belimo SF24A-SR-S2 – technical data

Rotary actuator with fail-safe function, designed for damper control in technical building systems. The analogue control signal sets the damper to its operating position while tensioning the return spring. If the power supply is interrupted, the spring moves the damper to the safety position.

Key features
