Drew33, National Instruments offers many different signal conditioning options (SSR Series, SCXI, SCC...) that work very well with the PCI-MIO-16xe-10 to control a solenoid valve. I recommend you contact our internal sales department at 1-800-433-3488. They specialize in specifying systems and will be able to help you choose the best hardware for your application.
