Digital In 1 - 3

The digital inputs are connected to pins 6, 7 and 8.
The GND connection for all digital outputs is on pin 2.
The input levels between 0 and 0.7 volts are evaluated as LOW signals.
Input levels between 2.7 and 24 volts are evaluated as HIGH signals.
Input levels between 0.7 and 2.7 volts are classified as undefined. Levels in this
voltage band can be measured both High and Low.
Operation in this area is to be avoided!
Via the digital inputs, for example, a release issued by a higher-level system can be
evaluated for the PxtXX system.
