Yes, our switch panel have LED indicator. the economical feedback solution is :
let relay controller output DC12V -> middle relay or SSR or AC contactor -> load (like lamp, socket) this DC12V just connect with power supply, so that you not need every channel have a independent DC12V power supply for feedback.
the middle relay can use removable relay (AC230V 16A) , so that if broken, can easily to replace.
