CAUTION!
Risk of overloading the analog input!
If an analog current sensor supplies a current in excess of 25 mA for more than
1 second during initialization, this input is switched off by the module (input pro-
tection).
Use only sensors with fast initialization or sensors without current peaks higher
than 25 mA. If this is not possible, protect the input by connecting a 10-volt
zener diode in parallel to I+ and I-.
