NI ELVIS II controlled solenoid valve

[Lepeck]

Greetings,

I am attempting to program a simple solenoid valve to shut off at a specific pressure using Labview and the ELVIS board. I am just struggling with how to wire my valve and power it with this breadboard. Everything I have seen to power this valve is utilizing an arduino and I am just not sure if I should use the same setup or if it should be wired differently (different components or completely different). I am pretty new to using this software and just want to make sure my connections are correct before turning the board on.

Here is the valve I currently have.

And here is a typical set up for the valve using an arduino.

Would I just need to connect my valve to my output, ground it, and then place a diode across the connection to protect my circuitry? It may be a silly question, but I just don't want to set it up incorrectly!

Any information will be helpful for me as I am just starting out!
Thanks for your time!

Hey Lepeck.

That solenoid will draw 320 mA at 12V. Your ELVIS board appears to have a positive variable output supply from 0-12 V available with a max current draw of 500mA. If you ran the solenoid at 11V, it would draw about 350mA.
Check out second to last page on their datasheet:

Keep in mind that you wont have much more room on your variable +12V rail. You still have 2 amps available on your +5 V rail, and 500mA on each of your -15 and +15 V rails. If you need more 12V room, you could always run a cheap regulator from 15 ->12 V and have ~ 580 mA to play with after losses (if switcher is used).
