Connecting To An Npn-Compatible Plc Device - Matrox Iris GT MIL Installation And Technical Reference

110 Appendix D: Using the I/O signals and controlled- current output of Matrox Iris GT

Connecting to an NPN-compatible PLC device

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