Representation
Reference potential for the digital inputs/outputs and analog input

Note
An open input is interpreted as "low".
The use of the digital inputs (DI 0 ... DI 3) requires terminal M2 be connected. This is achieved
by:
• Providing the reference ground of the digital inputs, or
• a jumper to terminal M. This removes the electrical isolation for these digital inputs.
