Belimo LM24A-SR modulating damper actuator for HVAC air dampers up to approx. 1 m²; AC/DC 24 V, 2–10 V modulating control, 2–10 V position feedback, 5 Nm, IP54 / NEMA 2, 150 s/90°, lockable manual override.
The Belimo LM24A-SR is a compact modulating rotary actuator used to precisely position HVAC air dampers in AHUs and duct systems. It accepts a 2–10 VDC control signal (Y) and drives the damper proportionally to the demanded position. A 2–10 VDC feedback output (U) provides continuous position indication for BMS monitoring, trending, and alarm verification.
The actuator mounts directly to the damper shaft using a universal shaft clamp (6–20 mm) and includes a lockable manual override push-button for commissioning and maintenance. Adjustable mechanical end stops allow you to limit rotation to suit the damper.
Applications
AHU fresh air / return air / exhaust air dampers (modulating control)
