Control & indicators
5 digital inputs (e.g. push button, switch, relay contact, ...). Input is generally "high" (1), connection to GND makes the input
"low" (0).
Analogue inputs (e.g. temperature sensor, potentiometer, ...) 0 ... +5VDC MAX!
If the jumper is mounted, then you can use the internal voltage and adjust it using RV2/RV1. If the jumper is not mounted you
must use the external voltage A2/A1.
Adjusting of the internal voltage for input A1.
Adjusting of the internal voltage for input A2.
