Axia GPIO Basic Examples

Updated 4 days ago by John (JP) Powell

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.
