The IO interface furnishes six galvanically isolated I/O 24V switching signals for the connection
with sensors, actuator or PLC.
All inputs and all outputs have a Common In or Common Out reference potential. This allows
using the I/Os either for PNP logic or NPN logic. A mixed mode (PNP and NPN at the same time)
is not possible.
These I/O signals can be used to control the camera or transfer individual information to the host
system. As a result, the image acquisition can be triggered via these I/O signals. Outputting a
binary analysis result is also possible. The assignment of the I/O signals is done via the BVS
Cockpit interface (see “Digital I/O interface” on page 29).

The supply voltage for the I/O of the I/O interface is galvanically isolated from the operational
voltage of the

.
2)
The maximum current for
Common In
and
Common Out
is 630 mA.
Below are examples how inputs and outputs must be connected to obtain input and output
function.
Notes
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 I/O connection
and I/O 0 at the power connection.
If the I/Os are configured as input, their signals are logically combined with OR. 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.
