Hi everybody,

I am new to this, so sorry if my question is stupid

I would be so thankful if someone could help

is it possible to turn on/off divices with Labview ? if yes, how can I do it ?

I have 2 devices and when one of them is on the other one has to turn off.

Well, you need some hardware.  If you have a DAQ card with a digital output, you could use that to drive a relay to turn one or the other on.  You'll have to pay attention to the current draw and voltage of the relay coil to make sure it works with the digital output.

You'll have to look at the current capacity and voltage rating of the relay contacts to make sure it can handle the voltage and current draw of your devices.
