Designed to provide a convenient 4 to 20 mA current output from a resistance transducer or potentiometer. A suitable high quality single or twenty-turn potentiometer can be supplied with the unit for applications in which an accurate adjustable 4-20 mA current can be controlled using the potentiometer. Simply connected in series with any DC power supply from 12 V to 32 V and the current through the unit is then controlled by the external resistance.  Current is independent of changes in the DC supply and the load resistance.
Applications:
Remote two wire setpoint control. Potentiometer to 4-20 mA conversion.
Resistance to 4-20 mA conversion.
Level transmission using float activated resistance switches.
Joystick interface.
