what does a relay card do exactly? (Electronics)

1.17K views

The best definition I could find online is:

These handy boards provide a simple method to interface a low level control output from a control system such as the FSR Flex Gpio ports to higher level loads such as a low voltage screen controller. They can also be used to reverse control output logic if necessary

**can someone break this down in layman’s terms?**

Please and thanks. I just bought a kit and am about to assemble a relay board… but I don’t know what I can use it for when it’s complete.
