invert DC output from 5 to 0 volt

[Myounggu]

Hi, I am a kind of beginner of Labview. I want drive solenoide valve of MFC. 5 V open and 0 V close. I am using DAQ 6008 and is there any simple way to do that? I am thinking of inverting 5 V output. Could you give some tips to do that? Thanks in advance.

You could probably use the Digital output line on your USB 6008 to control the solenoid

But better check if the solenoid is compatible with the sourcing capability of your Digital output line

Welcome to the discussion forums, Myounggu!

The USB-6008 user guide (page 22) indicates that it has open-collector (open-drain) digital outputs, so you will have to supply to source voltage to drive the line. As a new user to LabVIEW, I always recommend getting started with an example program. In LabVIEW, click on “Help » Find Examples” and search for the type of task you want to do. In your case, you can browse for examples by selecting “Hardware Input and Output » DAQmx » Digital Generation”. I would recommend starting with either “Write Dig Chan” or “Write Dig Port”.

An additional resource is this DAQmx tutorial which gets you familiar with the most common tasks in DAQmx.

Post again after looking at these resources if you have more questions.
