Solenoid Control for Water Flow

[callmewhatever]

Hi there!

I need to develop a program using labView to control the flow using solenoid valve (SMC VX3344-03T-5DS1-B) as water flow valve. What I currently have is NI9266 and NI cDAQ-9188 chassis.

However, I am a newbie in this environement and don't have no clude about the labView related knowledge at all, so, I've no idea which direction should I go to. So, I'be very thankful if anyone guide me the learning path and ideas to make it happen.

Thank you so much.

The NI9266 is a current output module, suitable to drive 0…20mA with a compliance voltage of 12V.

The solenoid is operated at 24V and most probably needs way more than 20mA.

I guess you should start with reading datasheets/specs for your (currently available) hardware, consult a electrical engineer in your department and order suitable hardware that fits your requirements!

When it comes to software you should learn LabVIEW by those Training resources offered at the top of the LabVIEW board. (And also learn how to spell LabVIEW… :D)

In the example finder, you can look through a library of examples. For your application, you'll probably want to look at:

Hardware Input and Output > DAQmx > Analog Output 

Hardware Input and Output > DAQmx > Digital Output

There's also an abundance of previous forum posts with similar issues. If you put "solenoid control" into the search bar, and go to community, there's plenty of other people with similar problems you can pick ideas from.

There's plenty of courses here to help you get started, depending on how new you are. 

Learn LabVIEW, get stuck, come back with code that has a problem.

A valve is an on/off device, your DAQ output is an analog current.

Your valve needs 24V DC/10.5W to operate, that is almost 440mA of current flow in activated state.

You need a relay or solid state relay output to activate your valve, not a current output!
