Connecting an auxiliary output signal to an inductive load input

Connect a Matrox Indio auxiliary output signal to an inductive load input, as
shown below.
An inductive load device, such as a traditional relay, requires that you use a
flyback diode to protect Matrox Indio from over and under-voltage, as shown
below. This diode should be connected as close as possible to the input and voltage
source of your inductive load device.
