Belimo TFB120-SR Actuator 324846-701 safety protocols may require anThe Belimo TFB120 SR is a professional grade spring return damper actuator designed for modulating control in robust HVAC systems. Engineered for high reliability fail safe operation, this 22 in lb torque actuator ensures positive close off on air tight dampers during power loss. Operating on a universal 100 to 240 VAC power supply, it accepts a 2 to 10 VDC modulating control signal (or 4 to 20 mA with a 500? resistor) to provide precise proportional
