Solid-state relays (SSR) currently hold>10% ntawm lub ntiaj teb relay lag luam, raws li cov ntaub ntawv VDC. Los ntawm txoj kev xav ntawm kev lag luam, txawm hais tias electromechanical relays tseem nyob rau hauv txoj hauj lwm tseem ceeb ntawm tag nrho cov relay kev lag luam, kun dicrystal khoom relay muaj cov yam ntxwv ntawm lub neej ntev, ceev teb, muaj kev ntseeg siab thiab tsis tshua muaj zog noj ntawm kev hloov pauv, thiab tau sai heev. qhov kev xaiv zoo tshaj plaws nyob rau hauv ntau daim ntawv thov, tshwj xeeb tshaj yog nyob rau hauv thermal hloov khoom siv thiab cua sov tswj kev lag luam. Tsis tas li ntawd, vim nws qhov me me thiab tsis tshua muaj suab nrov, cov khoom siv hluav taws xob hauv lub xeev kuj tau txais los ntawm cov khoom siv hauv tsev thiab cov khoom siv hauv tsev.
Tuam Tshoj txoj kev lag luam khoom lag luam relay yuav tsum rov qab los vim qhov kev xav tau zoo los ntawm kev lag luam xws li kev tswj tsis siv neeg, kev sib txuas lus, cov cuab yeej tiv thaiv hluav taws thiab kev ntsuas aviation. Tsis tas li ntawd, fax modems thiab PC phaib kuj tseem tuaj yeem txhawb kev muag khoom ntawm lub xeev relays. Kev loj hlob ntawm cov tshuab semiconductor ua rau qhov loj ntawm cov khoom me me thiab me, thiab tag nrho cov pob loj ntawm cov khoom hauv lub xeev relays kuj raug txo, yog li cov khoom hauv lub xeev relays muaj ntau dua thiab nrov hauv PC phaib thiab lwm yam kev siv, tshwj xeeb tshaj yog hauv caug thiab handheld modems.
solid state relay
VDC kwv yees tias yav dhau los yuav ua lag luam ntau dua li qhov sib txawv ntawm tus nqi sib txawv ntawm cov khoom siv hauv xeev thiab cov tshuab hluav taws xob relays qis dua thiab kev ua haujlwm nce ntxiv. Solid-state relays yuav tsum yog lwm txoj hauv kev siv hluav taws xob hluav taws xob yog tias lawv tuaj yeem txo cov nqi thiab txo cov pob ntau thiab tsawg thaum nce kev ua haujlwm thiab kev ua haujlwm.
Tuam Tshoj tuam ntxhab tab tom tsim cov khoom siv hluav taws xob hauv lub xeev tau sib xws nrog cov tsoos electromechanical relay pins. Cov khoom hauv lub xeev relay muaj lub neej ua haujlwm ntev, kev sib cais siab thiab tsis muaj kev sib cuag tsim, tuaj yeem txo qhov tsim ntawm electrostatic sparks, yog li kev lag luam yuav tsum tau ua lub hauv paus ntawm kev ua lag luam. Kun dijing tseem ntseeg tias cov khoom siv hluav taws xob hauv lub xeev txuag lub zog los hloov cov reed thiab electromechanical relays.
Ntxiv rau qhov loj me, cov neeg siv khoom tseem yuav tsom mus rau lub peev xwm thauj khoom ntawm relays thiab nrhiav cov khoom uas muaj kev tswj xyuas siab thiab kev tiv thaiv. Kun Erjing ntseeg hais tias cov neeg siv khoom them nyiaj ntau dua rau kev nyab xeeb thiab kev tswj hwm qib ntawm cov xwm txheej, ntau dua li kev tswj ceev. Cov tiam tom ntej ntawm solid-state relay cov khoom yuav yog digital solid-state relays, nrog kev hloov pauv ntau dua thaum tuav cov haujlwm uas twb muaj lawm.
