To connect your Matrox Iris E-Series to a NPN-compatible PLC device, the
ground of your Matrox Iris E-Series must be connected directly to the
NPN-compatible PLC device's ground. In addition, an output signal of your
Matrox Iris E-Series must be connected to the device's sinking input. You should
connect the ground of the NPN-compatible PLC device and the ground of your
Matrox Iris E-Series to a common ground.
The NPN-compatible PLC device provides its own power source. When the
Matrox Iris E-Series output signal is "on" the NPN-compatible PLC device
connects to ground and completes the circuit.
