The device 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 plug (see chapter 7.4).
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

NOTICE
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.
NOTICE
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!
