" . . .which provide analog inputs/outputs . . ."
The question is so fundamental you thought it was understood.
Provides I/O to what?
Do these devices only communicate with computers running monitor/control software? Or can they exchange data among themselves without computer supervision?
Can I plug one of these devices to my ethernet jack in room A and another to my ethernet jack in room B? And have unit B respond to the stimulus from room A? And vice versa?

They provide a link between the real world and software running on some host computer. The U12/U3/U6/UE9 cannot do what you describe by themselves, as without software on a computer somewhere they do very little.
A way to do what you describe would be to take a Linux SBC such as the TS-7500 and connect it to a U3. This gives you a networkable and programmable Linux computer with real-world I/O.
