Audluliselolicandelo le-elektroniki elisebenzisa imigaqo ye-electromagnetic okanye ezinye iziphumo ezibonakalayo ukuze kuphunyezwe "ukucima/okuzenzekelayo" kweesekethe. Umsebenzi wayo ophambili kukulawula ukukhutshwa kweesekethe ezinkulu zangoku / eziphezulu zombane kunye ne-current / signals encinci, ngelixa uphinda ufezekise ukuhlukaniswa kombane phakathi kweesekethe zokuqinisekisa ukhuseleko lwesiphelo solawulo.

Imisebenzi yayo ephambili ingahlelwa ngokweendidi ezintathu:

1. Ukulawula kunye noKwandiswa: Iyakwazi ukuguqula izibonakaliso zokulawula ezibuthathaka (ezifana ne-milliampere-level currents output by single-chip microcomputers kunye ne-sensor) zibe yimisinga enamandla eyaneleyo yokuqhuba izixhobo zamandla aphezulu (ezifana neenjini kunye nezifudumezi), ezisebenza "njenge-amplifier yesiginali". Ngokomzekelo, kumakhaya ahlakaniphileyo, imiqondiso emincinci yombane ethunyelwa ngee-apps zefowuni ephathwayo inokulawulwa ngokuhanjiswa ukuze kulayishwe kwaye kucinywe amandla ee-air conditioner zasekhaya kunye nezibane.

2. Ukuhlukaniswa kombane: Akukho xhulumaniso oluthe ngqo lombane phakathi kwesiphaluka solawulo (i-voltage ephantsi, i-current current) kunye nesiphaluka esilawulwayo (i-voltage ephezulu, i-current enkulu). Imiyalelo yolawulo ihanjiswa kuphela nge-electromagnetic okanye imiqondiso ye-optical ukuthintela amandla ombane aphezulu ukuba angangeni kwi-terminal yolawulo kwaye wonakalise izixhobo okanye abeke emngciphekweni ukhuseleko lwabasebenzi. Oku kuqhelekileyo kufumaneka kwiisekethe zolawulo lwezixhobo zoomatshini boshishino kunye nezixhobo zamandla.

3. Ingqiqo kunye noKhuseleko: Inokudibaniswa ukuphumeza i-logic yesekethe eyinkimbinkimbi, efana ne-interlocking (ukuthintela ii-motor ezimbini ukuqala ngexesha elinye) kunye nokulawula ukulibaziseka (ukulibazisa uxhulumaniso lomthwalo ixesha elithile emva kombane). Ezinye iireyiyi ezizinikeleyo (ezifana ne-overcurrent relays kunye ne-overheating relays) nazo zinokubeka esweni ukungahambi kakuhle kweesekethe. Xa i-current ikhulu kakhulu okanye iqondo lokushisa liphezulu kakhulu, baya kunqumla ngokuzenzekelayo isiphaluka ukukhusela izixhobo zombane kumonakalo ogqithiseleyo.
