    Hallo,

    I got hands on a used Controllino Maxi. I am not sure if it is working.

    Only the pins on top seem to be powered.

    I cannot measure current with a multimeter on the screw terminals when switched to high.

    How many amperes does the 12 volt transformer have to deliver to supply the screw terminals D0 … D11 ?

    Thanks.

    Hello,

    Do you have a load at outputs or are you connecting only the multimetr switched for current measurement ? ;-)

    Each output D0..D11 has overcurrent protection and can deliver maximum of 2 A. You have to have proper load connected to there. And based on the load you have to select the proper 12 V power supply for CONTROLLINO. If you have some of the loads for example 5 A, than approx. 5,5 A power supply shall be selected.

    Regards

    Hallo,

    i have only the multimeter switched to voltage measurement connected to the digital output and gnd.

    So a power supply with 12V and 1A should be sufficient? But 0V is being displayed.

    Thanks

    Hello,

    yes, power supply 12V/1A shall be fine for this type of tests.

    Do you have corresponding LED (D0-D11) on the TOP ON when you activate the output in your software?

    Regards

    OK, thanks.

    Just got a new controllino. Now all works fine and as expected.

    The LEDs indicate if outputs are high/low and the voltmeter measures 12V/0V.

    I Send back the used one. I think it is broken.

    Thank you for your help.
