    Hello Lucko,

    I am sorry for a late reply. I have tested your code (also placed below in my comment) with my CONTROLLINO MAXI Automation and it works fine and as expected.

    • MAXI is powered from 24VDC
    • I measure 0,04 V at AO0
    • When I connect 24 V to AI0 then only AI0 LED is ON
    • And I can measure 10,09 V at AO0

    Please note that I can use value 0 for analogWrite without any problems.

    So, maybe there is really something wrong with your device, but it may be also something with your compilation toolchain … please share with us the verbose output of the compilation when you observe the issue with the value 0.

    #include <Controllino.h>
    int outputPin = 12;
    int testPin = A0;
    void setup() {
    // put your setup code here, to run once:
    pinMode(outputPin, OUTPUT);
    pinMode(13, OUTPUT);
    pinMode(testPin, INPUT);
    analogWrite(outputPin, 0);
    analogWrite(13, 0);
    void loop() {
    // put your main code here, to run repeatedly:
    if (digitalRead(testPin)){
    analogWrite(outputPin, 255);
    analogWrite(13, 255);
    if (!(digitalRead(testPin))){
    analogWrite(outputPin, 1);
    analogWrite(13, 1);
