A relay yog ib qho yooj yim hloov khoom siv uas siv lub teeb liab me me los tswj lub teeb liab loj. Nyob rau hauv rooj plaub no low voltage pulses qhib los yog kaw ib tug ntau dua voltage Circuit Court. Xav txog ib relay raws li lub chaw taws teeb tswj kev hloov. Yog li a relay vaj huam sib luag ntxiv rau / tawm tswj rau ib lub voj voog, tab sis nws tseem yuav tsum tau noj los ntawm lub tshuab hluav taws xob vaj huam sib luag.
Dhau li ntawm no, lub teeb pom kev zoo relay ua haujlwm li cas?
A relay yog ib qho hluav taws xob hloov hluav taws xob ua haujlwm los ntawm cov hluav taws xob me me uas tuaj yeem qhib lossis tawm hluav taws xob loj dua. Lub plawv ntawm a relay yog ib qho electromagnet (ib lub kauj ntawm cov hlau uas dhau los ua cov hlau nplaum ib ntus thaum hluav taws xob ntws los ntawm nws).
Ib sab saum toj no, cov teeb pom kev zoo tswj lub tshuab ua haujlwm li cas? Teeb pom kev zoo tswj yog input/output pab kiag li lawm thiab tshuab . Cov tswj qhov system tau txais cov ntaub ntawv, txiav txim siab dab tsi ua nrog nws, thiab ces kho teeb pom kev zoo zog raws li. Ntawm no peb pom ib qho yooj yim teeb pom kev zoo Circuit Court (hloov ceg). Lub hwj chim taug kev raws lub voj voog kom muaj zog rau ib pab pawg teeb.
Dhau li ntawm no, dab tsi yog lub vaj huam sib luag relay?
A relay yog lwm lo lus rau kev hloov. Nws tuaj yeem yog qhov hloov pauv uas hloov qee yam rau / tawm lossis hloov pauv ntawm ob yam khoom. Nyob rau hauv lem, a relay vaj huam sib luag yog a vaj huam sib luag uas tuav ib lossis ntau dua relays uas xa hluav taws xob lossis teeb liab mus rau cov khoom siv raws li cov tswv yim tau txais.
12v relay ua haujlwm li cas?
Thaum qhov hluav taws xob raug tshem tawm ntawm lub coil davhlau ya nyob twg lub caij nplooj ntoos hlav rub lub armature rov qab rau hauv nws txoj hauj lwm 'thaum so' thiab rhuav tshem lub voj voog ntawm cov terminals. Yog li los ntawm kev thov lossis tshem tawm lub zog rau lub kauj (qhov qis tam sim no) peb hloov lub siab tam sim no rau lossis tawm.

Cov ntaub ntawv twg yog siv nyob rau hauv lub vaj huam sib luag ntes?
Indirect detectors muaj ib txheej ntawm cov khoom siv scintillator, feem ntau yog gadolinium oxysulfide lossis cesium iodide, uas hloov cov x-rays rau hauv lub teeb
Lub vaj huam sib luag ntsaws yog dab tsi?
Lub vaj huam sib luag mount receptacle tso cai rau koj los ntsaws cov khoom txuas ncaj qha rau hauv lub cuab yeej phab ntsa lossis cov khoom dai dawb rau kev sib dhos hauv-qhov chaw. Hom mount no tuaj yeem ntsia tau yuav luag txhua qhov chaw ntawm cov khoom chassis thiab yog qhov zoo rau cov khoom uas xav tau IP-rated tiv thaiv los ntawm plua plav lossis dej nkag
Lub vaj huam sib luag thaiv vaj huam sib luag yog dab tsi?
Structured Wiring thiab Networking Panels. Structured wiring yog ib lo lus dav dav uas hais txog lub network tag nrho ntawm cov suab, video, cov ntaub ntawv, xov tooj, TV, lub tsev automation lossis kev ruaj ntseg teeb liab. Cov kab hluav taws xob muaj peev xwm tuaj yeem ntsia tau thaum lub tsev nyob hauv kev tsim kho, retrofitted thaum hloov kho lossis ntxiv rau nws tus kheej
Dab tsi yog cov npe ntawm ob hom kev hloov pauv tsis ncaj nraim hauv vaj huam sib luag ntes?
Ob hom indirect: CCD thiab TFT ob leeg yuav tsum tau xray hloov dua siab tshiab rau lub teeb thiab ces mus rau hluav taws xob teeb liab nrog photodiode txheej
Yuav ua li cas koj qhia lub Appearance vaj huam sib luag hauv Illustrator?
Kev pom vaj huam sib luag pom koj siv lub vaj huam sib luag tshwm sim (Qhov rai> Qhov tshwm sim) los saib thiab kho cov cwj pwm zoo rau ib qho khoom, pab pawg, lossis txheej. Fills thiab strokes tau teev nyob rau hauv kev txiav txim stacking; sab saum toj mus rau hauv qab nyob rau hauv lub vaj huam sib luag correlates pem hauv ntej mus rau hauv lub artwork
