Output Circuits Construction - CS-Lab CSMIO IP-S User Manual

4.3.1 Output circuits construction

As you can see on the scheme, each
input is optically isolated. Outputs are
divided into groups, four in each group.
Each group is controlled by special-
ized chip VNQ860. These chips work in
PNP logic, thus the active state is a high
state (+24V).
VNQ860 circuits are not powered
from the same source CSMIO/IP is. If they
were, the opto-isolation would have no
sense. Therefore, we must remember to
supply power to each group of outputs
we use.
If we do not care about CSMIO/IP controller and digital outputs supply potentials separation and we
want to use one supply source then we can link power supply of all the groups (pins 1, 4, 7, 10) and
connect to controllers +24V supply. Of course you must also connect supply primary lines, 0V (pin 14,
17, 20, 23) to GND of CSMIO/IP controller power supply.
