The following connection diagram gives an example of how to connect an auxiliary device to the
AXIS Q7406.
AXIS Q7406
*12V max 100mA
Description
Digital input - Connect to GND
to activate, or leave floating (or
unconnected) to deactivate.
Digital output - Uses an open-
drain NFET transistor with the
source connected to GND. If
used with an external relay, a
diode must be connected in
parallel with the load, for
protection against voltage
transients.
