Digital I/O - IMAGO VisionBox AGE-X5 Hardware Manual

5 Interfaces

5.6 Digital I/O

The digital I/O interface provides two input and two output groups. Each group has eight signals
and all groups are electrically isolated from each other, as well as from other VisionBox circuits
and interfaces.
The following illustration shows the corresponding electrical equivalent circuit for one input and
one output group:

The input group requires external connection of a shared GND reference. For the output group,
the user must provide a supply voltage to the VCC pin which is used by all output signals. Every
input and output has an LED to show the current state of each channel.
