Belimo GMB24-SR Actuator Freon it engages the fan atThe Belimo GMB24 SR is a high torque, non spring return damper actuator engineered for precise proportional modulation in large scale HVAC systems. Delivering a robust 360 in lb torque, this unit is designed to automate dampers up to 90 square feet. It operates on a universal 24VAC DC power supply and accepts a standard 2 10VDC control signal, which can be adapted for 4 20mA signals using a 500? resistor. As the direct replacement for GM24 SR, the
