To connect your Matrox Iris GT to an inductive load device, you must first
connect a high-voltage diode between them. The diode protects your Matrox
Iris GT from high voltage, caused when disconnecting from the inductive load
device.
You should connect the negative side of the load (anode) and a Matrox Iris GT
output signal to the external diode. In addition, you should connect the positive
side (cathode) of the load to a +24 V power supply. When the Matrox Iris GT
output signal is enabled, the negative side of the load is reduced to 0 V, and 24 V
appears across the circuit.
+24V max.
