5.5 Connecting the PLC inputs to the electrical
system
WARNING
Danger due to components subjected to electrical overload
Material damage or personal injury can result from current that is too high at the inputs
and outputs.
► The voltage at the I/O port with regard to the protective conductor cable or the
ground potential must be less than 48 V DC or 25 V AC.
Technical data for the
PLC inputs
• Input voltage 24 V DC nom., 28 V DC max.
– Low level: 0 … 7 V
– High level: 13 … 28 V
Change from LOW to HIGH:
The programmed input function is activated (edge-controlled).
The PLC inputs and PLC outputs are electrically isolated.
