APD 4008 Series Potentiometer Transmitters

The APD 4008 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 APD 4008 will accept any potentiometer with a value of 0-100 Ω through 0-1 MΩ without recalibration and without affecting accuracy.

The APD 4008 output can be field-configured via external rotary and slide switches. Offsets and/or input ranges other than 0 to 100% of the potentiometer range can also be selected. The full 3-way (input, output, power) isolation makes this module useful for ground loop elimination, common mode signal rejection or noise pickup reduction.
