Pin assignments:

The following connection diagram gives an example of how to connect an auxiliary device to the

AXIS Q7404.

Function Pin number Notes Specifications

GND 1 Ground

3.3VDC

Power

2 Can be used to power auxiliary equipment.

Note: This pin can only be used as power out.

Max load = 250mA

Configurable

(Input or

Output)

3 - 4 Digital input - Connect to GND to activate, or

leave floating (or unconnected) to deactivate.

Min input = - 40V DC

Max input = + 40V DC

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.

Max load = 100mA

Max voltage = + 40V DC
