Electrical connection
Function as switching input
Switching input
Figure 7.1:
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 barcode
reader is, at the same time, configured as an output (and not as an input), the switching
output malfunctions.
Attention!
The maximum input current must not exceed 8mA!

Attention!
Each configured switching output is short-circuit proof! Do not load the respective switching
output of the BCL
Notice!
Both switching inputs/outputs SWIO_3 and SWIO_4 are configured by default in such a way
that:
• Switching input SWIO_3 activates the reading gate.
• Switching output SWIO_4 switches by default on "No Read"
