Inkcazo emfutshane:

I-relay yokukhusela i-voltage isebenzisa iprosesa enesantya esiphezulu nenamandla aphantsi

njengesiseko sayo. Xa umgca wombane une-voltage engaphezulu, i-voltage engaphantsi

, okanye ukusilela kwesigaba, ukubuyiselwa kwesigaba, i-relay iya kuyinqumla isekethe ngokukhawuleza

kwaye ngokukhuselekileyo ukuthintela iingozi ezibangelwa yi-voltage engaqhelekanga ethunyelwa

isixhobo sesiphelo. Xa i-voltage ibuyela kwixabiso eliqhelekileyo,

i-relay iya kuvula isekethe ngokuzenzekelayo ukuqinisekisa ukusebenza okuqhelekileyo

izixhobo zombane ezikwisiphelo sendlela phantsi kweemeko ezingajongwanga
