Nws puas tuaj yeem kuaj seb lub optocoupler puas zoo lossis phem nrog tsuas yog ib qho multimeter?
Daim ntawv thov hauv logic circuits Optocouplers tuaj yeem tsim ntau yam logic circuits. Txij li thaum cov kev cuam tshuam kev cuam tshuam thiab kev sib cais ntawm optocouplers zoo dua li cov transistors, cov logic circuits tsim los ntawm lawv muaj kev ntseeg siab dua. Siv los ua ib qho khoom siv hauv kev hloov hluav taws xob, feem ntau yuav tsum muaj kev sib cais hluav taws xob zoo ntawm kev tswj Circuit Court thiab qhov hloov, uas yog qhov nyuaj rau cov hluav taws xob hloov hluav taws xob, tab sis nws yooj yim rau kev ua tiav nrog photocoupler.
Daim ntawv thov nyob rau hauv trigger circuit Siv optocoupler rau bistable tso zis Circuit Court, txij li thaum lub teeb-emitting diodes tuaj yeem txuas rau hauv series mus rau ob lub emitter loops, nws tuaj yeem daws qhov teeb meem ntawm kev sib cais ntawm cov zis thiab load. Daim ntawv thov nyob rau hauv Pulse Amplifying Circuits Photocouplers yog siv nyob rau hauv digital circuits los nthuav cov mem tes signals.
Daim ntawv thov nyob rau hauv linear circuits Linear optocouplers yog siv nyob rau hauv linear circuits, nrog high linearity thiab zoo heev hluav taws xob cais kev ua tau zoo. Daim ntawv thov nyob rau hauv tshwj xeeb zaus Photocouplers kuj siv tau nyob rau hauv high-voltage tswj, hloov transformers, hu relays, thiab A / D circuits thiab lwm yam sij hawm.
Tom qab nyeem cov ntsiab lus saum toj no, koj paub tias optocoupler ua lub luag haujlwm tseem ceeb hauv Circuit Court. Yog hais tias lub optocoupler puas lawm, lub Circuit Court tsis tuaj yeem lav. Niaj hnub no peb yuav tham txog yuav ua li cas kuaj qhov zoo ntawm optocoupler. Nws tuaj yeem kuaj seb lub optocoupler puas zoo lossis phem.
Lub input davhlau ya nyob twg ntawm lub photocoupler yog lub teeb-emitting diode, yog li koj siv tau cov ntaub ntawv diode ntawm lub multimeter los txiav txim seb lub teeb-emitting diode puas. Nws yog tib yam li txoj kev ntsuas lub diode. Yog tias qhov ntsuas hluav taws xob poob qis tuaj yeem ntsuas tau (qhov rov qab txiav tawm lub xeev kuj tuaj yeem ntsuas tau), ces qhov yooj yim nws tuaj yeem txiav txim siab tias qhov kev tawm tswv yim kawg yog qhov zoo, tab sis dab tsi txog cov zis kawg tseem tsis paub meej.
Txij li thaum lub davhlau ya nyob twg tso zis tsuas yog qhib thaum nws tau txais cov teeb liab kho qhov muag los ntawm lub davhlau ya nyob twg, cov zis davhlau ya nyob twg yog nyob rau hauv lub xeev txiav tawm thaum lub input davhlau ya nyob twg tsis tau powered, yog li nws tsis tuaj yeem txiav txim seb nws puas yog ib txwm los ntawm ncaj qha ntsuas qhov tso zis davhlau ya nyob twg. Koj tuaj yeem siv cov tswv yim hauv qab no, txuas lub resistor hauv series mus rau lub input davhlau ya nyob twg thiab txuas lub hwj huam mov, siv ib tug multimeter los ntsuas qhov conduction voltage poob ntawm tus pin 4 thiab tus pin 3, uas yog ze rau 0 nyob rau hauv ib txwm muaj xwm txheej. .
Txij li thaum lub input davhlau ya nyob twg yuav tsum tau powered rau thaum txiav txim seb lub output davhlau ya nyob twg yog ib txwm, nws yog tsis yooj yim sua los txiav txim seb lub photocoupler yog ib txwm nrog ib tug multimeter.
