Izihlukanisi zedijithali ziyizingxenye ezibalulekile ezinhlelweni zesimanje ze-elekthronikhi, ezihlinzeka ngendlela ephephile nethembekile yokuhlukanisa amasekethe ahlukene kanye nokuvikela izingxenye ezibucayi.Njengoba ubuchwepheshe buqhubeka nokuthuthuka kanye nesidingo sokukhula okusheshayo, okusebenza kahle kwedijithali, ukubaluleka kwezihlukanisi zedijithali ngeke kugcizelelwe ngokweqile.Kulesi sihloko, sichaza izihlukanisi zedijithali, izinzuzo zazo, kanye nezicelo zazo.

I-isolator yedijithali iyisisetshenziswa esihlinzeka ngokuhlukaniswa kwe-galvanic phakathi kwamasekhethi amabili ahlukene kuyilapho ivumela ukudluliswa kwedatha yedijithali phakathi kwawo.Ngokungafani nama-optocoupler endabuko, asebenzisa ukukhanya ukuze adlulisele ulwazi, izihlukanisi zedijithali zisebenzisa ubuchwepheshe besignali yedijithali yesivinini esikhulu, okubenza basheshe futhi basebenze kahle.Badlulisela amasignali kuwo wonke umgoqo wokuzihlukanisa kusetshenziswa i-capacitive noma i-magnetic coupling, iqinisekisa ukuthi akukho ukuxhumana okuqondile kukagesi phakathi kwezinhlangothi zokufaka nokuphumayo.

Inzuzo eyinhloko yezihlukanisi zedijithali yikhono lazo lokuhlinzeka ngamazinga aphezulu okuzihlukanisa nokungavikeleki komsindo.Ngokusebenzisa amasu okucubungula amasignali athuthukile, lawa madivayisi ahlunga umsindo, aqinisekise ukuthi idatha edlulisiwe ihlala inembile futhi ithembekile.Lokhu kubaluleke kakhulu uma usebenzisana nezinhlelo ezisebenza ezindaweni ezinokhahlo ezinokuphazamiseka okuphakeme kazibuthe kagesi.Izihlukanisi zedijithali zinikeza isixazululo esiqinile ukusiza ukuhlukanisa izingxenye ezizwelayo kulo msindo, ukuqinisekisa ukuthi ukusebenza okuphelele kwesistimu akuthinteki.

Ukwengeza, izihlukanisi zedijithali zinikeza ukuphepha okuthuthukisiwe nesivikelo samathuluzi nabaqhubi.Ngokuhlukanisa amasekhethi ahlukene, lawa madivayisi avimbela amaluphu aphansi kanye nama-voltage spikes ukuthi angasakazeki ngohlelo, avikele izinto zikagesi ezibucayi emonakalweni.Lokhu kubaluleke kakhulu ezinhlelweni zokusebenza zezimboni ezifaka ama-voltage aphezulu noma ama-currents.Izihlukanisi zedijithali zivikela izinto ezisetshenziswayo ezibalulekile, zivimbela ukwehla ezibizayo, futhi okubaluleke kakhulu, ziqinisekisa ukuphepha kwalabo abasebenza eduze nezinhlelo zikagesi.

Ukwengeza, izihlukanisi ezidijithali zinikeza ukuguquguquka okukhulu kwedizayini nokubala kwezingxenye ezincishisiwe uma kuqhathaniswa nezihlukanisi zendabuko.Ngenxa yokuthi lawa madivayisi asebenza ngesivinini esiphezulu, angasetshenziswa kuhlelo olubanzi lwezinhlelo zokusebenza, njengokutholwa kwedatha yesivinini esikhulu, ukulawula kwezimoto, nokulawulwa kwamandla.Usayizi wayo ohlangene kanye nokulula kokuhlanganiswa kwayo kuyenza ilungele imiklamo ebamba isikhala.Ngezingxenye ezimbalwa ezidingekayo, izindleko eziphelele kanye nobunzima besistimu nakho kungancishiswa, okuholela kusixazululo esisebenza kahle nesingabizi kakhulu.

Kafushane, izihlukanisi zedijithali ziyizingxenye ezibalulekile ezinhlelweni zesimanje ze-elekthronikhi, ezihlinzeka ngokuhlukaniswa kwe-galvanic, ukungavikeleki komsindo, nokuphepha okuthuthukisiwe.Ikhono labo lokudlulisa idatha yedijithali ngesivinini esikhulu kanye nokuhlunga umsindo kuqinisekisa ukuxhumana okuthembekile phakathi kwamasekhethi ngamanye.Izihlukanisi zedijithali zithola ukuduma ezimbonini ezahlukahlukene ngenxa yohlu olubanzi lwezinhlelo zokusebenza namandla azo ezindleko nokonga isikhala.Njengoba ubuchwepheshe buqhubeka nokuvela, ukubaluleka kwabo ekuqinisekiseni ukuxhumana okuthembekile nokuvikelekile kuzoqhubeka nokukhula.
