Solenoid 12V Regulator on 24V Breakout?

They take in either 12 or 24vdc to drive a festo solenoid valve. Someone correct me if i'm wrong, if you purchased the 24v soelnoids from first choice, these would allow you to run them from either 12v or 24v supply.

Note that you will need to purchase two per double solenoid valve.

Wow we'll definitely be doing this

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.

This is correct. Those are simply connectors and do nothing to regulate voltage. They can be used for either 12v or 24v, but will not make the solenoid work with either voltage.

The 24v solenoids won't work on 12v. I helped a rookie team chase down why their pneumatics wouldn't work a couple of years ago. It was a frustrating pain and we tried everything until we realized that it was a 24v solenoid.
