Belimo GMB24-SR Damper Actuator

Belimo GMB24-SR Damper Actuator delivers direct-coupled, modulating, proportional control for HVAC systems. This non-spring return actuator operates on 24V AC/DC with a precise 2–10V DC output and a robust 360 in-lb torque for reliable damper positioning.

Designed for a 95° rotation and an IP54/NEMA 2 enclosure, it fits compact spaces (4.55" W x 2.9" D x 9.02" H) and accepts a 1/2" to 1.05" shaft. It runs at 50/60 Hz with a power rating of 4.5W running and 2W holding, optimizing energy use while maintaining response accuracy. The unit uses a 3 ft 18 AWG appliance cable with a 1/2" conduit connector and provides the 2–10V DC control signal with a 0.5 mA output.
