To interface the WISMO Quik Q24x6 Series digital signals with other logics :
3V logic : some serial resistors (between 2.2K and 4.7Kohms) can be
added on the lines
3.3V logic : some serial resistors (between 4.7K and 10Kohms) can be
added on the lines.
For higher voltage logics, a resistor bridge or a level shifter IC can be
added.
