Collect output status feedback and send it back to the control end

GA101 is bidirectional, so the output state can be fed back to the control end. When there is input on the left button, it will control the right fan to start, and at the same time drive the right middle relay to work. The output of the middle relay is collected by the right GA101 and synchronously transmitted back to the output indicator light of the left GA101.
