8.13 K90/K91, Control Unit with CompactFlash card with/without performance enhancement
Note
An open input is interpreted as "low".
The "fast inputs" can be used in conjunction with a measuring system for position sensing.
When externally generated 24 V DC signals are connected to a digital input, the ground
reference of the external signal must also be connected.
