I see in documentations that you can use up to 4 digital isolated inputs (I assume IO.0 to IO.3)

Where is the separate ground connector for these inputs?

Thank you for contacting us, 

In fact the GND is common but it has internally connected optocouplers for each input and also ESB isolation, 


I hope that this information helps.
