API 4008 G Series Potentiometer Transmitters

The API 4008 G 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 4008 G will accept any potentiometer with a value of 0-100 Ω through 0-1 MΩ without recalibration and without affecting accuracy as long as 100% of the potentiometer range is used. Models with offsets and/or input ranges other than 0 to 100% of the pot are available. Consult factory for assistance. The API 4008 G output can be field-configured via external rotary and slide switches. 10 DC voltage or 8 DC current ranges can be selected from the table on the module. Other output ranges are available. The full 3-way (input, output, power) isolation makes this module useful for ground loop elimination, common mode signal rejection or noise pickup reduction.
