Inputs as Digital Input

Each of the digital inputs labelled "A0" to "A.." can also be used as a digital input to measure a

switching status. If a logic "1" is measured the corresponding LED "A.." will be active. At a logic

"0" the corresponding LED "A.." will be off. This optical information can be used to get a quick

overview about the status of the inputs. This can be very helpful when carrying out error diagnos-

tics at a programming stage.

The logic levels depending on the supply voltages are:

Logic

Supply Voltage

Level

12V

0 to 3,6V

12V

9 to 13,2V

24V

0 to 7,2V

24V

18 to 26,4V

The maximum input current is < 3mA.

Digital Inputs (I0 to I...)

These inputs are only digital inputs. If a logic "1" is measured the corresponding LED "A.. " will be

active. At a logic "0" the corresponding LED "A.. " will be off. This optical information can be used

to get a quick overview about the status of the inputs. This can be very helpful when carrying out

error diagnostics at a programming stage.
