The external wiring as switching input and switching output is described in the following. For the respective
function assignment to the switching inputs/outputs see chapter 10.
Function as switching input
1
Switching input
2
Switching output from controller (deactivated)
3
Switching input to controller
Figure 7.3: Switching input connection diagram SWIO_3 and SWIO_4
If you use a sensor with a standard M12 connector, please note the following:
Pins 2 and 4 must not be operated as switching outputs if sensors which function as inputs are also
connected to these pins.
If, for example, the inverted sensor output is connected to pin 2, and pin 2 of the bar code reader is, at
the same time, configured as an output (and not as an input), the switching output malfunctions.
Function as switching output
1
Switching output
2
Switching input from controller
3
Switching output to controller (deactivated)
Figure 7.4: Switching output connection diagram SWIO_3 / SWIO_4
CAUTION
The maximum input current must not exceed 8 mA!
NOTICE
Each configured switching output is short-circuit proof! Do not load the respective switching output of the
device with more than 60 mA at +10 … +30 V DC in normal operation!
By default, the two switching inputs/outputs SWIO_3 and SWIO_4 are configured so that switch
-
ing input SWIO_3 activates the reading gate and switching output SWIO_4 switches on “No
Read”.
