4.1.2 Control input as analog input
To use the control input as an analog input, insert a resistance between the control input and con-
trol input ground pins. The four-channel selector knob, for example, contains a switch that
changes the resistance between the control input and control input ground pins.

4.2 Digital output
The digital output circuitry consists of an opto-isolated, solid-state relay for switching power to
external loads. The following table summarizes the AI-Delta's digital output opto-isolated field-
effect transistor (FET) values:
Type
