The power plug connector supplies the
SMARTCAMERA
with the supply voltage and
offers two I/O-24V switching signals (I/O 0 & I/O 1) for the connection with sensors, ac-
tuators or PLC.
These two inputs and outputs feature a push-pull output stage. This allows using the
output signal for PNP logic as well as NPN logic. The input stage always features PNP
logic.

Below are examples how inputs and outputs must be connected to obtain input and
output function.
Input connection
If I/O 0 is configured as input, it is sinking and can be connected directly with the PNP
output of a sensor, a PLC. A 1 signal is being detected if the input is connected with the
supply voltage. A 0 signal is being detected if the input is set to ground or is not connect-
ed.
If an NPN device is to be connected to the input, then an external level converter must
be connected upstream.
