Product information "Belimo SM230ASR-TP Modulating Damper Actuator (20Nm, 230V-Class, 2–10V, Terminal Type)"

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

  • AHU fresh/return/exhaust air dampers (modulating control)
  • Mixing box / economizer dampers (proportional positioning)
  • BMS/DDC control sequences using 2–10 V with feedback for verification and alarms
  • Projects needing terminal wiring and wide-range AC supply
