    Hello,

    What about to try doing contact to the input with a cable connected to 12v, and after connected to 0V, and check if the eratic state of the input is gone ? If so, it would mean, I think, that you need a pullup or pulldown resistor, depending to your project.
    Or maybe a switch connected for exemple NC to 12v and NO to 0V ?

    I think you can have a look on the Atmega 2650 microcontroller datasheet, as it is the one used in controllino Mega.
    Still my opinion : the internal pullup resistance would be those of the Atmega. So its datasheet would tell you. And so there is no internal pulldown resistors.
