Hawsha ugu weyn ee optokoupler ee wareegga sahayda korantada waa in la ogaado go'doominta halka beddelka korontadu ay ka fogaato faragelinta labada dhinac. Shaqada goynta ayaa si gaar ah uga dhex muuqata wareegga.
Digniintu waxay u socotaa hal dhinac. Gelida iyo soo saarista gabi ahaanba waa go'doonsan yihiin koronto. Digniinta wax-soo-saarka wax saamayn ah kuma laha wax-soo-gelinta. Awood xoog leh oo ka-hortagga faragelinta, hawlgal xasilloon, xiriir la'aan, nolol adeeg oo dheer iyo waxtarka gudbinta sare. Optocoupler waa qalab cusub oo la sameeyay 1970-yadii. Waqtigan xaadirka ah, waxaa si ballaaran loo isticmaalaa in dahaarka korantada, beddelka heerka, isku xirka isdhexgalka, wareegga wadista, wareegga beddelka, chopper, multivibrator, go'doomin signal, go'doomin interstage, garaaca garaaca garaaca wadnaha, qalab digital, gudbinta signal masaafada fog, amplifier garaaca, qalab adag-state, Relay gobolka (SSR), qalab, qalabka isgaarsiinta iyo microcomputer interface. Korontada beddelka monolithic, optocoupler-ka tooska ah ayaa loo isticmaalaa si loo sameeyo wareegga jawaab-celinta optocoupler, iyo wareegga waajibaadka waa la beddelaa iyadoo la hagaajinayo korantada hadda jirta si loo gaaro ujeeddada nidaaminta korantada saxda ah.
Hawsha ugu weyn ee muraayadda indhaha ee beddelka sahayda korontadu waa inay go'doomiso, bixiso calaamad-celin iyo beddelasho. Korontada muraayadaha indhaha ee wareegga sahayda korantada ee wareejinta waxaa bixiya koronta labaad ee beddelka-soo noqnoqda sare. Marka korantada wax soo saarku ay ka hooseyso danabka zener-ka, shid calaamadda indhaha oo kordhi wareegga shaqada si aad u kordhiso tamarta wax soo saarka. Taas bedelkeeda, daminta muraayadaha indhaha waxay yareyn doontaa wareegga shaqada waxayna yareyneysaa tamarta wax soo saarka. Marka culayska labaad ee taransfooriyaha-soo noqnoqda sare uu si xad dhaaf ah u buuxo ama wareeggu furmo, ma jiro wax koronto ah oo kor u kaca ah, isla markaana muraayadda indhaha ayaa koontaroolaysa wareegga beddelka in aanu gariirin, si ay uga ilaaliso tuubada beddelka in ay gubato. Optocoupler waxaa badanaa lagu isticmaalaa TL431. Labada iska caabiyeyaasha ayaa si taxane ah loogu muunadeeyay terminaalka 431r marka la barbar dhigo isbarbardhigga gudaha. Kadib, marka loo eego calaamadda isbarbardhigga, iska caabbinta dhulka ee dhamaadka 431k (dhammaadka halka anode-ku ku xiran yahay optocoupler) ayaa la xakameynayaa, ka dibna iftiinka iftiinka iftiinka iftiinka ee muraayadda indhaha ayaa la xakameynayaa. (waxaa jira diodes iftiin leh oo dhinac ka mid ah muraayadaha indhaha iyo sawir-qaadaha oo dhinaca kale ah) xoogga iftiinka iftiinka ee dhex maraya. Xakamee iska caabbinta dhamaadka CE ee transistor-ka dhanka kale, beddel chip-ka korantada LED-ka, oo si toos ah u hagaaji wareegga waajibaadka calaamadda soo-saarka si loo gaaro ujeedada xasilinta danab.
Marka heerkulka ambient-ku si aad ah u isbeddelo, heerkulka qulqulka ee qodobka wax-weyneynta waa weyn yahay, taas oo aan lagu ogaanin muraayadaha indhaha. Wareegga indho-indheynta waa qayb aad muhiim u ah beddelka wareegga sahayda korontada.
