ISO7220BDR Dijital Masu Ware Hannu Hi Spd Dual Channel Dijital Mai Isolator

Na'urorin iyali na ISO7220x da ISO7221x sune masu keɓancewar dijital na dualchannel.Don sauƙaƙe shimfidar PCB, tashoshi suna daidaitawa a hanya iri ɗaya a cikin ISO7220x kuma a gaban kwatance a cikin ISO7221x.Waɗannan na'urori suna da madaidaicin shigarwa da buffer fitarwa wanda ke raba shingen keɓewar silicon-dioxide (SiO2) TI, yana ba da keɓewar galvanic har zuwa 4000 VPK akan kowane VDE.Ana amfani da su tare da keɓantattun kayan wutar lantarki, waɗannan na'urori suna toshe babban ƙarfin lantarki da keɓe filaye, haka kuma suna hana hayaniya a cikin motar bas ɗin bayanai ko wasu da'irori daga shiga cikin gida da yin katsalandan ko lalata hanyoyin kewayawa.
