Boolean from voltage

[rhoward99]

I am controlling a valve which has a limit switch that supplies 2.5 volts when it is open and -2.5 volts when it is closed. I would like to convert this voltage value to a boolean for easy input to an LED.

Being new to LabVIEW, I'm not sure if there is a built-in way to do this. I don't have an DIO's available, so I am reading the value through an analog terminal.

Currently, I am using a compare node and setting the value to "T" if > 1 and "F" if < 1.

Is there a better way?

Thanks!

Sure that works.

If I'm not misinterpreting what you're saying, you could just wire a >0 comparison with the numeric input and the boolean output to your LED. Or <0 if the logic was the other way around.
