Great! I have developed a chemical process that I control with an Arduino. We're going to make these systems, so these terminal blocks make it very easy to connect about ten sensors and control five relays. Since all systems will be the same, we can pre-assemble screw-on expansion boards and leave them "on the shelf". We can then connect them to the Arduino as needed.
