Ko te mahi matua o te optocoupler i roto i te hiko hiko hiko ko te mohio ki te wehe i te wa e huri ana te whakaahua hiko me te karo i te pokanoa tahi.Ko te mahi o te momotu he mea tino kitea i roto i te ara iahiko.
Ka haere te tohu ki tetahi huarahi.Ko te whakauru me te putanga ka tino wehea e te hiko.Ko te tohu whakaputa kaore he paanga ki te whakauru.He kaha ki te aukati i te aukati, te mahi pumau, kaore he whakapiri, te roa o te ratonga me te pai o te tuku.Ko te Optocoupler he taputapu hou i whakawhanakehia i nga tau 1970.I tenei wa, ka whakamahia nuitia i roto i te whakamaarama hiko, te hurihanga taumata, te honohono i waenga, te taraiwa taraiwa, te whakawhiti iahiko, te tapatapahi, te multivibrator, te tohu tohu, te wehe i waenga i te waahi, te hikoi whakakaha i te hiko, te taputapu mamati, te tuku tohu tawhiti-tawhiti, te whakakaha puhoi, te totoka. -te taputapu a te kawanatanga, te reera o te kawanatanga (SSR), te taputapu, te taputapu korero me te atanga rorohiko miihini.I roto i te hiko whakawhiti monolithic, ka whakamahia te optocoupler linear ki te hanga i te ara iahiko urupare optocoupler, a ka huri te huringa mahi ma te whakatika i te naianei kapeka mana ki te whakatutuki i te kaupapa o te whakaritenga ngaohiko tika.
Ko te mahi matua o te optocoupler ki te whakawhiti i te mana hiko ko te wehe, te tuku tohu urupare me te huri.Ko te mana o te optocoupler i roto i te hiko whakawhiti hiko e whakaratohia ana e te ngaohiko tuarua o te huringa teitei.Ina he iti iho te ngaohiko whakaputa i te ngaohiko zener, whakahurihia te optocoupler tohu me te whakanui ake i te huringa mahi hei whakanui ake i te ngaohiko whakaputa.Engari, ko te whakakore i te optocoupler ka whakaiti i te huringa mahi me te whakaheke i te ngaohiko whakaputa.A, no te nui o te kawenga tuarua o te whakawhiti tere-nui, ka kore ranei te hiko o te whakawhiti, kaore he mana o te optocoupler, a ka whakahaerehia e te optocoupler te hiko o te whakawhiti kia kaua e wiri, kia tiakina ai te ngongo whakawhiti mai i te wera.Ka whakamahia te Optocoupler me te TL431.Ko nga parenga e rua ka whakatauirahia i roto i nga raupapa ki te tauranga 431r hei whakataurite ki te whakatairite o roto.Na, i runga i te tohu whakataurite, ka whakahaeretia te parenga whenua o te 431k mutunga (te mutunga kei te hono te anode ki te optocoupler), katahi ka whakahaerehia te kanapa o te diode rama i roto i te optocoupler.(kei te taha o tetahi taha o te optocoupler me nga phototransistors kei tera taha) te kaha o te rama e haere ana.Whakahaerehia te parenga i te pito CE o te transistor i tetahi atu pito, huri i te maramara puku mana arahina, ka whakatika aunoa i te huringa mahi o te tohu whakaputa kia tutuki ai te kaupapa o te whakapumau ngaohiko.
I te huringa o te pāmahana ambient, he nui te paheketanga o te pāmahana o te mea whakakaha, e kore e kitea e te optocoupler.Ko te arahiko optocoupler tetahi waahanga nui o te huri iahiko hiko hiko.
