Product Description
BVS SC-_1280Z00-07-0_0
SMART
CAMERA
IO
english
The power plug connector supplies the
SMART
CAMERA
with the supply voltage and offers two
I/O-24V switching signals (I/O 0 & I/O 1) for the connection with sensors, actuators 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.
Information
I/Os of the same name are logically connected with each other.
When operating the I/Os as output, then e.g. I/O 0 is connected at the power connec-
tion and I/O 0 at the IO connection.
If the I/Os are configured as input, their signals are ored. A 1 signal is recognized if a 1
signal is present either at I/O 0 of the power connection or I/O 0 of the I/O connection.
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 connected.
If an NPN device is to be connected to the input, then an external level converter must be con-
nected upstream.
