FUNCTIONAL DESCRIPTION
The DC2 Series line of potentiometers are designed for use as a command signal for Proportion-Air control
valves. A 10 volt reference is used to provide excitation to the potentiometer. An op-amp measures the output
on the wiper of the potentiometer and provides buffering to eliminate external components from affecting the
linearity of the potentiometer. A three wire cord is provided and is attached to the pc board to make necessary
power signal and common connections.
