    Maalmahan, PLC waxay heli kartaa cod-bixiye iyo calaamadaha dareemayaasha iyada oo aan lahayn cod-weyneeye, haddaba waa maxay madadaalada "ilo" iyo "daadi"? Kaliya wax soo saarka PLC ayaa lahaan doona fikradaha "source" iyo "leakage".

     

    Dhab ahaantii, marka laga reebo Jabbaan PLC, looma baahna PLC-yada kale inay isticmaalaan soo-gaabista sida "ilo" iyo "daadi", laakiin PNP iyo NPN si toos ah ayaa loo isticmaali karaa.

     

     

     

    PNP waa khad dadweyne oo koronto yar leh, NPN-na waa khad dadweyne oo koronto ah. Ilaa inta xidhiidhkani uu sax yahay, waxa ay u muuqataa in aanay waxba yeelayn haddii fikradaha "ilo" iyo "daadi" la rogo. Si kastaba ha ahaatee, fikrad kale "positive Logic iyo negative Logic" ayaa sidoo kale khaldan, taas oo keeni doonta in calaamadda la rogo.

     

     

     

    Lojig togan iyo caqli xun

     

    Wareegyada nooca PNP, meesha guud ee sahayda korontada iyo calaamaduhu waa heer hoose oo 0V ah. Marka galinta uu ku jiro heer hoose, ma jiro farqi danab ah oo u dhexeeya terminalka caadiga ah, sidaa darteed ma jiro wax soo saar calaamad beddel ah oo la xoojiyay (tirada dijitalka ah waa 0). Kaliya marka la gelinayo heer sare ah, waxaa jira kala duwanaansho koronto leh terminalka caadiga ah iyo signalka beddelka la xoojiyay ayaa soo baxaya heer sare. Habkan dhijitaalka ah (tiro dhijitaal ah waa 1) kaas oo wax ku ool ah marka calaamaduhu heer sare marayo waxaa loo yaqaan 'PNP positive logic'.

     

     

    In wareegga NPN, terminalka caadiga ah ee korontada iyo calaamaduhu waa heer sare (sifada wareegga cod-weyneeye). Marka wax-soo-gelinta ay ku jirto heer sare, ma jiro farqi danab ah oo u dhexeeya wax-soo-gelinta iyo soo-saarka, markaa ma jiro wax-soo-saarka calaamadda beddelidda (tirada dhijitaalka ah waa 0). Kaliya marka wax gelinta ay ku jirto heer hoose (samaynta funnel), waxaa jira soo saarida signalada wareejinta, calaamadani waa mid wax ku ool ah (tiro dijital ah waa 1) qaab dhijitaal ah oo heer hoose ah, kaas oo loo yaqaan 'NPN negative logic'.
