Lub ntsiab lus ntawm PCB-Relay

PCB relay yog ib qho me me relay uas tuaj yeem txuas ncaj qha rau PCB. Cov relays zoo li muaj qhov ntsuas hluav taws xob siab thiab tuaj yeem txuas mus rau lub rooj tsavxwm raws li cov khoom siv los ntawm lub qhov vim lawv qhov loj thiab qhov hnyav. Ib lub relay yog siv thaum twg muaj qhov xav tau los tswj lub siab voltage Circuit Court nrog lub zog qis thib ob. Qhov txiaj ntsig ntxiv ntawm kev xa xov hluav taws xob yog kev sib cais galvanic, uas tsis muaj nrog kev hloov pauv ntawm transistor. PCB relays muaj nuj nqi zoo ib yam li lwm yam relay, tab sis lawv zoo li yuav ua tau ntau dua thiab muaj qhov ntsuas qis dua. Cov khoom no kuj tuaj nyob rau hauv ib qho ntawm cov qauv tsim koj yuav pom nyob rau hauv loj relays.

PCB-Relay ua haujlwm li cas

Ib tug relay tsis muaj dab tsi tab sis ib tug electromagnetic hloov. Qhov tseem ceeb tshaj plaws yog electromagnetic coil. Thaum tam sim no dhau los ntawm nws, nws hloov mus rau hauv cov hlau nplaum kub. Qhov chaw sib nqus no ua haujlwm los ntawm cov phaj hlau uas txuas mus rau armature, hloov qhov chaw sib cuag. Yog li, lub magnetic teb activates lub armature thiab ua los yog lov cov kev twb kev txuas nrog rau qhov chaw sib cuag. Qhov no tsim kev hloov pauv raws li daim teb tuaj yeem qhib lossis kaw cov neeg sib cuag. Qhov no yog qhov yooj yim ua haujlwm ntawm relay.

Q: Dab tsi yog qhov zoo ntawm PCB relays?

A: PCB relays yog ib qho kev txhim khu kev qha, qhov chaw zoo, ntau yam, thiab cov neeg siv khoom siv tau zoo rau cov tshuab hluav taws xob thiab lawv muaj ntau yam zoo rau cov tshuab hluav taws xob. Nov yog qee qhov ntawm cov no:
Lawv muab kev ntseeg tau tshwj xeeb thiab kav ntev, ua kom muaj kev ruaj ntseg txawm tias nyob rau hauv kev xav tau.
Lawv qhov loj me me thiab qhov chaw txuag tsim ua rau lawv zoo tagnrho rau cov ntawv thov uas qhov chaw txwv.
PCB relays muaj ntau yam thiab sib xws nrog ntau yam kev siv, muab kev yooj yim hauv kev tsim qauv.
Cov relays paub txog lawv qhov yooj yim ntawm kev teeb tsa thiab kev saib xyuas, ua kom yooj yim cov txheej txheem rau cov kws tshaj lij thiab txo qis sijhawm.

Q: Dab tsi yog hom PCB relays raws li txoj cai ua haujlwm?

A: PCB relay categorization nyob ntawm cov qauv, qhov chaw, daim ntawv thov, thiab kev sib cuag. Siv cov xwm txheej no, peb muaj cov kev faib tawm hauv qab no ntawm relays.
Electromagnetic Relays
Electromagnetic relays muaj cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob uas txav cov khoom siv sib cuag thaum qhib. Lub hauv paus tseem ceeb ntawm qhov system no yog electromagnet, uas tsim ib qho chaw sib nqus kom qhib lossis kaw cov kev sib cuag. Koj tuaj yeem siv AC lossis DC hauv qhov relay no, thiab ntau hom yog induction thiab attraction hom.
Solid State Relays
Hloov mus rau hauv lub xeev cov khoom siv hluav taws xob siv cov khoom siv semiconductor, tsis yog cov khoom siv tshuab. Tsis tas li ntawd, cov cuab yeej no muaj lub zog nce siab dua li electromagnetic PCB relay. Qhov kev nce siab no yog vim lawv cov kev tswj hwm qis zog txheeb ze rau lawv cov khoom siv hluav taws xob siab. Lub zog-state relay muab kev hloov pauv sai dua li cov qauv PCB lub zog relay. Tsis tas li ntawd, nws ua haujlwm ntsiag to thiab muaj lub neej ntev vim tsis muaj kev sib cuag. Qee qhov piv txwv muaj xws li photo-coupled thiab transformer-coupled relays.
Hybrid Relays
Cov relays no suav nrog cov khoom siv hluav taws xob thiab hluav taws xob ua haujlwm ua ke tab sis nyob rau hauv qhov chaw sib luag. Qhov hluav taws xob ntawm lub relay tswj kev kho, thaum lub electromagnetic tivthaiv saib xyuas cov khoom seem. Qhov txiaj ntsig tseem ceeb ntawm kev teeb tsa no yog qis zog poob piv rau cov khoom siv hauv lub xeev relays, ua rau txo qis kev siv hluav taws xob.
Thermal Relays
Thermal relays hloov los ntawm reacting rau qhov kub thiab txias hloov thiab hloov chaw sib cuag. Txij li qhov kub hloov pauv ua rau kev hloov pauv, cov relays tiv thaiv cov khoom siv los ntawm overheating. Cov no muaj xws li motors thiab bimetallic nta xws li kub sensors.

Q: Dab tsi yog hom PCB relays raws li kev cuam tshuam thiab ncej?

A: Raws li lawv qhov kev cuam tshuam thiab cov ncej, koj tuaj yeem sib txawv PCB relays rau hauv plaub pawg.Cov plaub pawg no zoo ib yam li cov uas sib faib cov keyboards tsis tu ncua: SPST, SPDT, DPST, thiab DPDT.
SPST
Ib leeg-ncej ib leeg-throw relays muaj plaub qhov sib txuas, uas yog thawj thiab theem nrab circuits muaj ob lub davhlau ya nyob twg. Lub hauv paus Circuit Court tseem nyob tas li nyob rau hauv tag nrho plaub hom, yog li qhov cuam tshuam thiab ncej sib txawv ntawm lub voj voog load. Hauv kev teeb tsa no, lub voj voog thib ob muaj qhov hloov ib txwm qhib (NO) lossis ib txwm kaw (NC). Nrog NO hom, lub kauj kaw lub voj voog thaum muaj zog. Tab sis nrog hom NC, lub kauj qhib lub voj voog thaum muaj zog.
SPDT
Ib leeg-ncej ob-txheej hloov pauv muaj ob lub voj voog ntawm ob sab (ob-thib), uas tso cai rau lawv tswj ob lub cuab yeej. Sab NC tseem siv tau los ntawm lub neej ntawd, tab sis kev sib cuag hloov mus rau NO sab thaum koj ua kom lub zog ntawm lub kauj. Qhov kev txiav txim no muab lub zog ntws mus rau NC sab, hloov mus rau NO sab.
DPST
Muaj ob tug ncej, txhua tus nrog ib qho pov tseg, DPST yog sib npaug rau ob lub SPST circuits. Yog li ntawd, qhov relay no tuaj yeem siv ob lub cuab yeej ua ke. Nco ntsoov, SPDT relays tuaj yeem tswj tau ob lub voj voog tab sis lub zog tsuas yog ib zaug xwb. Tab sis DPST PCB relays tuaj yeem siv hluav taws xob lossis tua ob qho tib si.
DPDT
Ob-ncej ob-txoj kev hloov pauv zoo li ob lub SPDT kev sib cuag hauv ib lub cuab yeej. Yog li ntawd, cov relays no tuaj yeem tswj tau plaub lub voj voog, qhov uas lub zog ntawm lub kauj tuaj yeem ua rau ob lub NO circuits thiab tua lwm ob NC hu. Thaum tawm, tus relay thim rov qab cov neeg sib cuag, ua rau cov kab tawm (NC) thiab tua TSIS TAU.

Q: Cov khoom siv PCB relay yog dab tsi?

A: Cov khoom siv PCB relay yog hais txog ib pob lossis cov txheej txheem uas suav nrog tag nrho cov khoom tsim nyog thiab cov ntaub ntawv xav tau los sib sau ua ke ntawm PCB relay ua haujlwm.
