Gulce,
When you wire to the cRio solenoid module you have to supply power to the interface board. The module only provides closing contacts it does not provide the power to control the modules. There is a nice schematic on the side of the module that will explain this. You can choose 12 volts or 24 volts depending on the solenoids you are using. If you are using 24 volt solenoids, you can obtain that in parallel with the cRio power supply on the PD.
