Ko te mahi matua a te optocoupler i roto i te ara iahiko tuku hiko ko te whakatutuki i te wehenga i te wā e huri ana i te hiko whakaahua me te karo i te pokanoa tetahi ki tetahi. He mea tino kitea te mahi a te momotu i roto i te ara iahiko.
Kotahi te ahunga e haere ana te tohu. He hiko motuhake te whakauru me te putanga. Kāore he pānga o te tohu putanga ki te whakauru. He kaha te ārai-whakararuraru, he pumau te mahi, kāore he pa, he roa te ora ratonga, ā, he pai te tuku. He taputapu hou te Optocoupler i whakawhanakehia i te tekau tau atu i 1970. I tēnei wā, he whānuitia te whakamahinga i roto i te whakamahana hiko, te hurihanga taumata, te hononga i waenga i ngā wāhanga, te ara iahiko taraiwa, te ara iahiko whakawhiti, te tapatapahi, te wiri maha, te wehewehe tohu, te wehewehe i waenga i ngā wāhanga, te ara iahiko whakanui pātere, te taputapu matihiko, te tuku tohu tawhiti-roa, te whakanui pātere, te taputapu āhua-totoka, te whakawhiti āhua (SSR), te taputapu, ngā taputapu whakawhitiwhiti kōrero me te atanga rorohiko iti. I roto i te pūtake hiko whakawhiti kotahi, ka whakamahia te optocoupler raina hei hanga i te ara iahiko urupare optocoupler, ā, ka whakarerekētia te huringa mahi mā te whakarerekē i te iahiko pito whakahaere kia tutuki ai te kaupapa o te whakahaere ngaohiko tika.
Ko te mahi matua a te optocoupler i roto i te pūhiko whakawhiti ko te wehe, te whakarato tohu urupare me te pana. Ko te pūhiko o te optocoupler i roto i te ara iahiko pūhiko whakawhiti ka whakaratohia e te ngaohiko tuarua o te whakawhiti auau-teitei. Ina iti iho te ngaohiko putanga i te ngaohiko zener, tahurihia te optocoupler tohu ka whakanuia te huringa mahi hei whakanui ake i te ngaohiko putanga. I tetahi atu taha, mā te whakaweto i te optocoupler ka whakaitihia te huringa mahi ka whakaitihia te ngaohiko putanga. Ina taumaha rawa te kawenga tuarua o te whakawhiti auau-teitei, ina rahua rānei te ara iahiko pana, kāore he pūhiko optocoupler, ā, ka whakahaere te optocoupler i te ara iahiko pana kia kaua e wiri, kia tiakina ai te ngongo pana kei wera. Ko te optocoupler te tikanga e whakamahia ana me te TL431. Ka tauirahia ngā ātete e rua i roto i te raupapa ki te pito 431r hei whakataurite ki te whakataurite ā-roto. Kātahi, e ai ki te tohu whakatairite, ka whakahaeretia te ātete whenua o te pito 431k (te pito e hono ana te anode ki te optocoupler), kātahi ka whakahaeretia te kanapa o te rama-whakaputa rama i roto i te optocoupler. (he rama-whakaputa rama kei tetahi taha o te optocoupler me ngā phototransistors kei tetahi taha) te kaha o te rama e haere ana. Whakahaeretia te ātete i te pito CE o te transistor i tetahi atu pito, hurihia te maramara taraiwa hiko LED, ka whakarite aunoa i te huringa mahi o te tohu putanga kia tutuki ai te kaupapa o te whakau i te ngaohiko.
Ina huri tere te pāmahana o te taiao, ka nui te nekehanga pāmahana o te tauwehe whakanui, kāore e tika kia kitea e te optocoupler. He wāhanga tino nui te ara iahiko optocoupler o te ara iahiko tuku hiko whakawhiti.
