controlling a 12 volt supply

[Lab Student]

I'm using labview to set a system that will turn on and off an external 12 volt power supply. I'm using a USB based DAQ which controls a SSR. I guess Labview will open or close the relay to turn on and off the supply voltage to the device.Are there any examples of what will be required to do this in Labview, or are there any suggestions?

Lab Student,

There are examples that will do this in LabVIEW. I am assuming your DAQ board supports NI-DAQmx and has a digital I/O port. If you open up the NI Example Finder (from inside of LabVIEW go to Help > Find Examples) and browse to Hardware Input and Output > DAQmx > Digital Generation. All of the examples in this directory do digital output, which one you want to use depends on your application. Write Dig Chan.VI will probably work well for your application.
