Use of analog inputs as digital inputsΒΆ
Several (or all) analog inputs can be configured as digital inputs Digital/Analog Input/Output Module DA502. The inputs are not electrically isolated against the other analog channels.
The following figure shows the connection of digital sensors to the analog input AI0. Proceed with the analog inputs AI1 to AI3 in the same way.
