Belimo AFB24-MFT Damper Actuator 24V AC DC 50 60 Hz

Belimo AFB24-MFT is a fail‑safe, direct‑coupled damper actuator designed for 24 V AC/DC operation at 50/60 Hz, delivering 180 in‑lb (20 Nm) of torque with 95° of travel. It uses Belimo's Multi‑Function Technology (MFT), allowing programmable modulation via a 2–10 VDC control signal and including two SPDT outputs in a NEMA 4X enclosure for rugged HVAC environments. The spring‑return design provides a reliable fail‑safe position when power is lost, and the unit measures about 3.42 in × 3.15 in × 9.69 in, making it suitable for compact damper applications. Typical uses include damper actuation in air handling units and variable air volume dampers where precise positioning and fail‑safe operation are critical.
