The breakout boards are supplied power, usually 12v, from the PB Board. One for the analog breakout the other for the solenoid breakout. The cRio is supplied power form the 24v Wago connector on the PD board.
Remove the wiring from the solenoid breakout at the PD board end and put them in the 24v Wago connecter on the PD Board ( The one supplying 24v to the cRio ) The 24v Sauro connector is labeled as V,C,NC,C
Usually you put the cRio positive connection on (V) and put the negative connection on the outer (C).
Instead wire it with the cRio positive on (V), like before, put the cRio negative on the (C) next to it. Then put the positive to the solenoid breakout on (NC) and the negative solenoid breakout wire in the outer (C).

You can still use 12v solenoids but will have to actuate them with Spikes.

We do this on our robot, using the 24v higher Cv flow solenoid from the solenoid breakout for our catapult and the older 12v solenoid controlled by a spike off the sidecar for out shifter.

Works very well.

Aloha!
