Njengoba imikhiqizo yamakhasimende iba mikhudlwana futhi ibe namandla ngokwengeziwe, othintana nabo, abafanele ukulawula amandla aphezulu, basetshenziswa njengemishini yokushintsha imithwalo yemishini ehlukahlukene kagesi edinga amandla aphezulu wamanje kanye naphezulu.
Kodwa-ke, ngenxa yesidingo esikhulayo sezinto zokusebenza ezincane, ezingasindi, nezizacile, umkhuba wokushintsha izixhumi ezinkulu kufakwa amabhodi amancane,{0}}anamandla amakhulu aphrintekayo webhodi (PCB) okwazi ukuphazamisa amandla kagesi aphezulu kanye naphezulu empeleni ayakhuphuka.
Ngaphezu kwalokho, amanye amakhasimende, alindele ukwanda kwesidingo sesikhathi esizayo kanye nokwanda kwevolumu yokukhiqiza, asebenzisa ukudluliselwa kwe-PCB ukunciphisa izindleko ngokuhlanganisa imishini yokushintsha umthwalo ebhodini lesifunda eliphrintiwe, njengesinyathelo esisodwa sokunciphisa isikhathi sokukhiqiza.
Isithiyo esinzima kakhulu sezengqondo okufanele sinqobe ekushintsheni abathintwayo ngokudlulisela i-PCB wushintsho olubalulekile lwedizayini oludingekayo ukuze kuthathelwe indawo izintambo zekhebula ezivamile ngezintambo "ezisekelwe ebhodini{0}".
I-PCB relay iyisisetshenziswa sokulawula sikagesi esihlanganiswe ebhodini lesekethe eliphrintiwe. Ngokuhlanganisa i-relay nebhodi lesifunda, ukuhlelwa kwesifunda okuhlangene nokunembile kufinyelelwa. Umsebenzi wayo oyinhloko ukulawula izinga eliphezulu lamanje eliphansi, okulenza lifanele ukulungiswa okuzenzakalelayo, ukuvikela ukuphepha, nezinhlelo zokusebenza zokushintshwa kwesekethe.
