API 4003 G I Potentiometer Transmitters

The API 4003 G I accepts a resistance input from potentiometer, slidewire, linear position, displacement, or rotational devices and provides an optically isolated DC voltage or current output that is linearly related to the potentiometer position.

The API 4003 G I will accept any potentiometer with a value of 0-100 Ω through 0-1 MΩ without recalibration and without affecting accuracy. The API 4003 G I output is factory ranged. Consult factory for offsets and/or input ranges other than 0 to 100% of the potentiometer range or see the APD 4008. The full 3-way (input, output, power) isolation makes this module useful for ground loop elimination, common mode signal rejection, and noise pickup reduction.
