Axia GPIO Pinout

Updated 4 months ago by John (JP) Powell

For information about using an external power supply and other application notes, consult the Axia xNode manual's GPIO section.

Pins 1-5 - Outputs 1-5
Pin 7 - Output Common Return

This is the reference input for active outputs. When an output is active, the corresponding output pin is connected to this pin. For a closure to ground (low when active), connect this pin to ground (pin 8)

For an Example Output, Click Here

Pin 8 - 0V (GND) Source

Ground or negative connection for the internal +5V DC source (pin 9)

Pin 9 - +5V DC Power Source

This pin provides 100mA of current for logic.

Pin 10 - Input Common

This is the reference for the input triggers. When an input is idle, it is the same value as this pin. For normally high active low inputs, connect this pin to the 5V Power source.

Pins 11-15 - Inputs 1-5

For an Example Input, Click Here


  • Current Limit for inputs = 20mA per input
  • Current Limit for outputs = sum shall not exceed 100mA
  • Current Limit for 5V Source = 100mA
  • Maximum reference input voltage = 24V
