The AUD converts a floating-point signal into a linear analogue output. There are Two inputs on the AUD, one to increase the analogue output and one to decrease the analogue output.
The output of the AUD is stable when the inputs are both off.
A contact closure or voltage signal to either input will cause the output of the AUD to begin to ramp either up or down depending on which input was activated. If both inputs are “ON” the output will reset to the lowest value of the selected range.
