Belimo Part Number: LMB24-SR Proportional Control, Non-Spring Return, 24 VAC or DC power, 2 to 10 VDC or 4 to 20 mA control signal
Application For proportional modulation of dampers in HVAC systems. Actuator sizing should be done in accordance with the damper manufacturers specifications. The actuator is mounted directly to a damper shaft from 1/4 up to 5/8 in diameter by means of its universal clamp. Shafts up to 3/4 diameter can be accommodated by an accessory clamp.
The actuator operates in response to a 2 to 10 VDC, or with the addition of a 500 resistor, a 4 to 20 mA control input from an electronic controller or positioner. A 2 to 10 VDC feedback signal is provided for position indication or master-slave  Technical Data Sheet
