Sezvo zvigadzirwa zvemutengi zvichikura uye zvine simba, macontactor, akakodzera kudzora simba rakawanda, anoshandiswa semidziyo yekuchinjisa mitoro yemidziyo yakasiyana yemagetsi inoda yakakwira ikozvino uye yakakwirira voltage.
Zvisineyi, nekuwedzera kuri kuda kwemidziyo midiki, isingaremi, uye yakatetepa, tsika yekutsiva macontactor mahombe nemadiki,-akakwirira akadhinda bhodhi redunhu (PCB) relay anokwanisa kukanganisa magetsi emagetsi akakwira ari kuwedzera.
Uyezve, vamwe vatengi, vachitarisira kuwedzera kudiwa kweramangwana uye kuwedzera kwehuwandu hwekugadzira, vari kushandisa PCB relays kuderedza mutengo nekubatanidza michina yekuchinja mitoro pabhodhi redunhu rakadhindwa, sechiyero chimwe chekucheka nguva yekugadzira.
Chipingaidzo chepfungwa chakaomesesa kukunda mukutsiva macontactor nePCB relays ndiwo magadzirirwo akakosha anodiwa kutsiva tambo dzekare ne "board{{0}based" wiring.
A PCB relay mudziyo wemagetsi wekudzora wakabatanidzwa pabhodhi redunhu rakadhindwa. Nekubatanidza relay nebhodhi redunhu, compact uye intuitive circuit layout inowanikwa. Basa rayo repakati ndere kudzora yakakwira ikozvino ine yakaderera ikozvino, ichiita kuti ive yakakodzera kugadzirisa otomatiki, kuchengetedza kuchengetedza, uye dunhu switching application.
