# Axia GPIO Basic Examples

## Example GPIO Input

In this example, the inputs are normally high because the **Input Common** (pin 10) is connected to **+5V** (pin 9)

An Input is activated when it is pulled low by connecting it to **Ground** (pin 8)

Inputs can be converted to normally low by connecting the **Input Common** (pin 10) to **Ground** (pin 8).

## Example GPIO Output

In this example, outputs are connected to ground when active since the **Output Common** (pin 7) is connected to **Ground** (pin 8).

The "customer device" in this example may be the coil of a relay, since it uses the 5V supply to complete a circuit. If the device connected to the output only needs a closure to ground, then the 5V supply source will not be necessary.
