I don't think this part works this way, but the documentation I've come across isn't 100% clear on this point. My reading of things is this particular part can work with either 12 or 24V valves, but only when the applied voltage matches the specifications of the valve. There are both 12 and 24V valves in the same family that can be used with this part. In other words, this part is more like a connector and does not regulate the voltage or anything like this. I think you're stuck using valves that take the same voltage, using two pneumatics modules in your cRIO, or using a Spike for 12V and a pneumatics module for 24V. Not only would putting a voltage regulator in-line violate the rules (from past years), but this would also likely not work, at least not very well. Maybe a resistor could be used, but this would likely run into the same issues, at least with the rules.

Bottom line: I would check very carefully before trying this, particularly given the costs involved if testing destroyed a valve or one were to go bad at an event.
