The SR2800 is a low-cost, reliable, potentiometer input two-wire transmitter for field or panel mounting in various industrial housings and enclosures. It provides a DC output current (4/20 mA) proportional to the wiper position of a potentiometer.

The module utilizes a stable 2.5 VDC power supply to excite the potentiometer. Any value potentiometer from 1 kilohm to 50 kilohms may be used. The output ZERO and SPAN controls are accessible through the top of the case. Terminations are made to screw terminal connections on the top of the case.

Test points located on the SR2800 front panel allow verification of loop current value, with a millimeter, without breaking the loop current.
