    Whakataki hua

    I enei wa, ka taea e te PLC te tango i nga tohu encoder me nga tohu puoro kaore he whakanui, na he aha te ahuareka o te "puna" me te "whakaheke"? Ko te putanga o te PLC anake ka whai i nga ariā o te "puna" me te "leakage".

     

    Ko te tikanga, haunga mo te Japanese PLC, kaore e tika kia whakamahia e etahi atu PLC nga whakapoto penei i te "puna" me te "whakaheke", engari ka taea te whakamahi tika i te PNP me te NPN.

     

     

     

    Ko te PNP he raina ngaohiko iti a te iwi, a ko te NPN he raina ngaohiko teitei. I te mea e tika ana tenei hononga, te ahua nei kare he aha mena ka huri ke nga kaupapa o te "puna" me te "whakaheke". Heoi ano, ko tetahi atu ariā "positive logic and negative logic" kei te he ano, ka huri te tohu.

     

     

     

    Te arorau pai me te arorau kino

     

    I roto i nga ara iahiko momo PNP, ko te tauranga noa o te tuku hiko me te tohu kei te taumata iti o te 0V. Ina he iti te whakaurunga, karekau he rerekee ngaohiko me te tauranga noa, na reira kaore he whakaputanga tohu whakawhiti whakakaha (he 0 te rahinga mamati). I te mea anake kei te taumata teitei te whakaurunga, ka puta he rereketanga ngaohiko me te tauranga noa me te tohu whakawhiti whakakaha ka puta ki te taumata teitei. Ko tenei aratau matihiko (ko te rahinga matihiko he 1) e whai hua ana i te wa kei te taumata teitei te tohu ka kiia ko te PNP positive logic.

     

     

    I roto i te ara iahiko NPN, kei te taumata teitei te tauranga noa o te tuku hiko me te tohu (te ahuatanga o tenei iahiko whakakaha). I te wa o te whakaurunga i te taumata teitei, kaore he rereketanga o te ngaohiko i waenga i te whakauru me te putanga, na reira kaore he putanga tohu whakawhiti (ko te rahinga mamati he 0). I te wa kei te taumata iti te whakaurunga (te hanga i te kohanga), ka puta he whakaputanga tohu whakawhiti, ka whai hua tenei tohu (te rahinga matihiko ko te 1) te aratau mamati i te taumata iti, e kiia nei ko te NPN kino arorau.
