The maximum cable length that can be connected is 30 m.
Note
An open input is interpreted as "low".
Terminal M2 must be connected so that the digital inputs (DI0 ... DI3) can be used. This is
achieved through one of the following measures:
• Provide the ground reference of the digital inputs.
• A jumper to terminal M (this removes the electrical isolation for these digital inputs).
Note
A 24 V supply voltage must be connected to terminal X124 for the digital outputs to be used.
If momentary interruptions in the voltage occur in the 24 V supply, the digital outputs are
deactivated until the interruption has been rectified.
