Belimo GKX24-SR is a direct-coupled, electronic fail-safe damper actuator designed for HVAC applications. Powered from 24V AC/DC, it delivers about 40 Nm (360 in-lb) of torque for reliable, precise damper positioning. It supports modulating control via 2–10 VDC or 4–20 mA signals and returns to a fail-safe position when power is removed, ensuring a known damper state on loss of power. The direct-coupled design eliminates external linkages, simplifying installation on dampers and enabling straightforward retrofits and new installations alike.
