I kēia manawa, hiki i ka plc ke loaʻa i nā hōʻailona a me nā hōʻailona sensor me ka amplifier, no laila he mea leʻaleʻa "? ʻO ka mea wale nō ka hopena o PLC e loaʻa nā manaʻo o ka "Source" a me "leakage".

I kaʻoiaʻiʻo, koe wale nōʻo Kepani Plc,ʻaʻole pono ia no nā plcs'ē aʻe e hoʻohana i nā pōkole e like me "kumu", akā, akā, akā naʻe, akā naʻe, akā naʻe, akā naʻe, akā naʻe, akā naʻe, akā naʻe, akā naʻe, akāʻaʻole hiki ke hoʻohana pololeiʻiaʻo PNN

ʻO PNP kahi laina haʻahaʻa haʻahaʻa haʻahaʻa, aʻo NPN kahi laina kiʻekiʻe kiʻekiʻe-Voltage-Voltage-Voltage. E like me ka lōʻihi o kēia piliʻana,ʻaʻole ia he meaʻaʻole ia he meaʻole inā he kumu o ka "Source" a me ka "Drain". Eia nō naʻe,ʻo kekahi manaʻo'ē aʻe "maikaʻi a maikaʻiʻole a maikaʻiʻole" hewaʻole, e kumu ai ka hōʻailona.

ʻO ka loiloi maikaʻi a maikaʻiʻole

Ma nā helu PNP-Type,ʻo ka pae o ka mana o ka mana a me ka hōʻailona ma kahi haʻahaʻa haʻahaʻa o 0v. I ka wā e waiho ana ka helu helu ma kahi haʻahaʻa haʻahaʻa,ʻaʻohe loli o ka uila me ka palena maʻamau, no lailaʻaʻole i loaʻa ka helu schange ʻO ka wā wale nō i ka wā kiʻekiʻe ma ke kiʻekiʻe kiʻekiʻe, aia kahiʻokoʻa voltage me ka hōʻailona maʻamau a me kahi hōʻailona hoʻololi i hoʻololiʻia ma ke kiʻekiʻe kiʻekiʻe. ʻO kēia mode digital (ka nui o ka nui o ka nui o ka 1) kahi mea e pono ai ke kapaʻia ka hōʻailona ma kahi kiʻekiʻe.

I ka NPN Circuit,ʻo ke kikowaena maʻamau o ka mana o ka mana a me ka hōʻailona ma ke kiʻekiʻe kiʻekiʻe Ke hele nei ka helu helu ma ke kiʻekiʻe kiʻekiʻe,ʻaʻoheʻokoʻa o ka uila ma waena o ka hoʻokomo a me ka hopena, no lailaʻaʻohe mea hōʻailona hōʻailona (). ʻO ka wā e waiho wale ana ka helu helu (ma kahi haʻahaʻa haʻahaʻa), aia kahiʻano hōʻailona hōʻailona he 1) i kapaʻiaʻo npn ka mea haʻahaʻa haʻahaʻa.
