Product information "Belimo NM230A-SR-TP Modulating Damper Actuator (10Nm, 230V-Class, 2–10V, Terminal Type)"

The Belimo NM230A-SR-TP is a compact modulating rotary actuator for precise positioning of HVAC air dampers in AHUs and duct systems. It is driven by a 2–10 VDC control signal (Y) and provides 2–10 VDC position feedback (U) for BMS monitoring, trending, and damper-proof verification.

The TP version uses connecting terminals (clean panel wiring / site installation). It features selectable rotation direction, lockable manual override, adjustable mechanical end stops, and overload protection with automatic stop at end position.

Applications

  • AHU fresh / return / exhaust air dampers (modulating control)
  • Mixing box / economizer dampers (proportional positioning)
  • BMS/DDC sequences using 2–10 V with continuous feedback
  • Retrofit projects requiring terminal wiring and wide-range AC supply
