KC868-A8's "INPUT" is digital input port, use by dry contact signal, or "0v" or "12v" voltage level signal. if you want to feedback AC230V, the easist way is find a small DC12v power supply. when this power supply have AC230V then will output DC12v, let it connect to KC868-A8's input port directly.
