Described in the following is the external wiring for use as a switching input or output; the
respective function assignments to the switching inputs/outputs can be found in chapter 10.
Function as switching input

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 504

with more than 60mA at +10 … +30VDC in normal operation!
