Connecting an auxiliary output signal to an inductive load input
Connect a Matrox 4Sight EV6 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 4Sight EV6 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.
