Belimo SM230ASR-TP modulating damper actuator for HVAC air dampers up to approx. 4 m²; AC 100–240 V (85–265 V), 2–10 V control, 2–10 V feedback, 20 Nm, IP54 / NEMA 2, 150 s/90°, with connecting terminals and lockable manual override
The Belimo SM230ASR-TP is a robust modulating rotary actuator for precise positioning of HVAC air dampers in AHUs and duct systems. It operates with a 2–10 VDC control signal (Y) and provides a 2–10 VDC position feedback (U) for BMS monitoring and trending of damper position (0–100%).
The TP version is built for panel/field wiring using connecting terminals (separate terminals for supply and control). It includes a lockable push-button manual override, adjustable mechanical end stops, and overload protection with automatic stop at end position (no limit switches required).
Applications
