SW IN/OUT – Switching input/switching output
The BCL 504
i
is equipped with four freely programmable, opto-decoupled switching inputs
and outputs
SWIO_1 … SWIO_4
.
The two switching inputs/outputs
SWIO_1
and
SWIO_2
are located on the
SW IN/OUT
M12
socket. The other two (
SWIO_3
and
SWIO_4
) of the four freely configurable switching
inputs/outputs are located on the
PWR
M12 connector and are described in chapter 7.2.1.
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!
