Belimo LM24A-SR Modulating Rotary Actuator 5 Nm 24V AC/DC 2–10V

The Belimo LM24A-SR is a compact modulating rotary actuator designed for accurate control of small dampers and valves within HVAC and building automation systems. Operating on a 24V AC/DC power supply, this actuator delivers 5 Nm of torque and uses a standard 2–10 V control signal, allowing precise modulation for efficient airflow and fluid control.

Engineered for reliable operation, the LM24A-SR provides smooth positioning with a running time of approximately 150 seconds for a full 90° rotation. The actuator also includes a 2–10 V position feedback signal, allowing building management systems (BMS) to monitor damper or valve position and optimise system performance and energy efficiency.
