Product information "Belimo LM230ASR-TP Modulating Damper Actuator (5Nm, 2–10V, 230V-Class)"

The Belimo LM230ASR-TP is a compact modulating rotary actuator used to precisely position HVAC air dampers in AHUs and duct systems. It accepts a 2–10 V control signal and drives the damper proportionally. A 2–10 V feedback output provides continuous position monitoring for BMS trending, alarms, and control verification.

The TP version is supplied with connecting terminals (instead of pre-wired cables), making it ideal for control panels and structured site wiring. The actuator includes lockable manual override, selectable rotation direction, adjustable mechanical end stops, and overload protection for reliable operation.

Applications

AHU fresh/return/exhaust dampers (modulating control)
Economizer and mixing box dampers (proportional positioning)
VAV / pressure control sequences requiring stable damper modulation
BMS systems using 2–10 V control + 2–10 V feedback for monitoring and alarms
Retrofit projects needing wide-range AC supply (100–240 V)
