Differential Inputs
The IN/OUT2 connector also includes two differential, optically isolated input circuits that can be used with
sourcing or sinking signals, 12 to 24 volts. They are labeled IN7 and IN8. These inputs allow connection
to PLCs, sensors, realys and mechanical switches. Because the input circuits are isolated, they require a
source of power. If you are connecting to a PLC, you should be able to get power from the PLC power sup-
ply. If you are using relays or mechanical switches, you will need a 12-24 V power supply. This also applies
if you are connecting the inputs to the programmable outputs of another Si product from Applied Motion.
