control lightbulb

[raghnie]

Hello everyone, 

Can someone please help me. How can I control a light bulb in labview? 

Because of the low voltage I need to use a relay. Can I use the single keyes relay of 5v? 

And how do I connect this all?

Hi raghnie,

to control an external device you need some DAQ devices.

Which one do you plan to use?

What is a "single keyes relay of 5v"?

Hi raghnie!

As GerdW said, you need to use a DAQ device in order to use digital and analog Inputs/Outputs. Using a DAQ, you will be able to read a current state of the light bulb and use that information for writing a signal to the light bulb in order to control it from LabVIEW.

All you have to do is use the DAQ Outputs to write the signal to the bulb and use the DAQ Inputs to read the current state of the bulb. Also you have to use the relay as a power amplifier stage.

I hope this information will help you 🙂
