Belimo LM24A-SR-TP 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°, with connecting terminals and lockable manual override.
The Belimo LM24A-SR-TP is a compact modulating rotary actuator for precise positioning of 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 damper position indication for monitoring, trending, and alarms.
The TP version is supplied with connecting terminals (instead of fixed cables), which is ideal for panel-based wiring and clean site installation. The actuator includes a lockable manual override, selectable direction of rotation, adjustable mechanical end stops, and overload protection for reliable operation.
Applications
AHU fresh air / return air / exhaust air dampers (modulating control)
Economizer and mixing-box dampers (proportional positioning)
Pressure/airflow control sequences requiring stable modulating damper control
BMS applications using 2–10 V control + 2–10 V feedback for supervision
Retrofit and new installations where terminal wiring is preferred
