Belimo LF24-MFT2 – rotary actuator with safety function

The actuator is used to position dampers in technical building systems. During operation, it tensions the return spring; when the power supply is interrupted, the spring moves the damper to its safety position. The device can operate with analogue control or receive a control signal via MP-Bus.
