Barber Colman Proportional Actuator w/ 4 to 20 mA input (120V)

The MPR-5600 series and MPR-5700 series actuators are used for electronic proportional control of dampers and valves which require a return to the normal position upon power interruption. MPR-5600 series actuators are compatible with controllers generating 4 to 20 mA input signals, and MPR-5700 series actuators are compatible with 135 ohm slidewire controllers (Series 90). Features Proportional actuators controlled by a variable mAdc input signal Fixed 4 to 20 Adc operating range 82.5 ohm input impedance Adjustable actuator startpoint
