Yuav tsum muaj dab tsi rau Rs485?

1, cov hom pib RS485 cable
RS485 cov kab ke tau faib ua ob hom: Twisted khub cables thiab cov cuab yeej sib dhos sib dhos khub.
Twisted khub Cable (STP -120 ω)
Twisted khub cable yog ib hom feem ntau hauv RS485 kev sib txuas lus, feem ntau sau npe tias yog stp {}} ω (rau RS485 & tuaj yeem), nrog khub ntawm 18AWG. Hom cable no muaj ob lub xov hlau ua ke, uas tuaj yeem txo cov hluav taws xob hluav taws xob hauv hluav taws xob thiab txhim kho kev kis qhov zoo. Stp -120} ω lable yog haum rau sab hauv tsev, xa hluav taws xob, thiab cov chaw muaj kev lag luam dav dav. Cov uas hla sab nraud ntawm lub cable yog li 8.2mm, nrog cov yam ntxwv grey, thiab nws muaj cov yam ntxwv ntawm tus nqi qis, yooj yim installation, thiab txij nkawm.
Armored Twisted Khub Tes Tiv Thaiv Cable (ASTP -120 ω)
Armored Twisted Khub Randinged Cesles Ntxiv Txheej Ua Ntej Txheej Txheem Rau Saum Cov Poj Niam Sib Tw, Muaj Peev Xwm Cov Hluav Taws Xob Ntau Dua thiab Kev Tiv Thaiv Kev Tiv Thaiv Ntau Dua. Hom cable no tseem yog lotp -120 ω (rau RS485 & muaj peev xwm), nrog lub cheeb ntawm 10.3mm, thiab lub ntsej muag dub. Armored Twisted Khub Cov Lus Cog Tseg yog tsim nyog rau cov chaw nrog kev cuam tshuam loj, thiab cov hluav taws xob nquag, xws li automations ib puag ncig, thiab lwm yam.
2, tus qauv thiab cov yam ntxwv ntawm RS485 Cable
Ntxiv rau cov hom pib yooj yim, RS485 CABLES kuj tseem tuaj yeem muab tau los ua ntau yam qauv raws li cov xwm txheej sib txawv.
Rs 485-2 hom

Hom cable no muaj ib tus qauv yooj yim, tus nqi qis, thiab tsim nyog rau kev sib txuas lus hauv ob-taw tes lossis txawj ntse network cov qauv nrog cov khoom noj uas tsis tshua muaj thiab yooj yim.
Rs 485-3 hom
Lub rs 485-3} Cable ntxiv rau hauv av xaim (GND) ntawm Rs {1} {1} {1} {1} {1} {1} {1} {1}}, uas txhim kho teeb meem tshwm sim los ntawm kev cog lus tsis zoo. Hom kev siv cable no tshwj xeeb rau kev siv nyob rau hauv ib puag ncig nrog electromagnetic cuam tshuam, xws li automation.
Rs 485-4 hom
Lub rs 485-4 Cable tsis tsuas yog suav nrog kab ntawv sib txawv, tab sis kuj ntxiv cov hluav taws xob zoo thiab tsis zoo rau kev sib txuas hauv lub npav. Hom cable no yooj yim simplaws tsim qauv thiab txo qhov xav tau rau kev tsim kho cov tshuab hluav taws xob, tshwj xeeb tshaj yog thaum txuas yooj yim.
Rs 485-5 hom
Lub rs 485-5 Cable sib xyaw ua ke txhua qhov ntawm cov kab saum toj no - A / B Cov cable no muaj qib siab tshaj plaws ntawm kev tiv thaiv kev cuam tshuam thiab yog qhov haum rau kev ua haujlwm nyob rau hauv cov xwm txheej huab. Rau cov ntawv thov uas yuav tsum muaj kev ntseeg siab heev thiab raug rau kev cuam tshuam hauv hluav taws xob hauv hluav taws xob, rs 485-5 yog qhov kev xaiv zoo tshaj plaws.
3, Qhia rau xaiv Rs485 cables
Thaum xaiv RS485 cables, cov hauv qab no yuav tsum tau txiav txim siab:
Kev Sib Kis
Lub loj dua cable taub, qhov deb dua qhov kev ncua deb. Txawm li cas los xij, nws tseem yog ib qho tseem ceeb kom them sai sai rau cov kev tiv thaiv cov nyhuv ntawm cov cable. Cov txiaj ntsig zoo yuav ua tau zoo txo ​​qhov cuam tshuam sab nraud sab nraud thiab yog li txhim kho kev sib nrug.
Electromagnetic cuam tshuam
Nyob rau hauv ib puag ncig nrog hluav taws xob muaj zog hluav taws xob, xws li {{1} {cleshents, lossis xaiv cov cuab yeej sib xyaw ua ke.
tus nqi
Yog tias cov peev nyiaj tau txwv, koj tuaj yeem xaiv Rs 485-2 cable nrog tus nqi qis. Txawm li cas los xij, nyob rau hauv cov xwm txheej uas muaj kev pab cuam siab thiab kev sib tw ntev, yuav tsum muab rau COABLE hom nrog kev ua tau zoo dua.
Daim Ntawv Thov Kev Pab Cuam
Xaiv cov hom kev tsim nyog sib xyaw raws li cov ntawv thov sib txawv. Piv txwv li, nyob rau sab nraum zoov lossis harsh chaw, armored twisted khub khub yuav tsum tau xaiv; Hauv cov xwm txheej uas yooj yim xaim yog qhov yuav tsum tau, Rs {{0} {cables tuaj yeem xaiv.
Cov Khoom Siv Tau Ntau
Thaum xaiv cables, nws tseem tsim nyog los xav txog qhov sib xws ntawm cov khoom siv. Piv txwv li, yog tias cov cuab yeej txhawb nqa cov xov tooj rau lub teb chaws, tom qab ntawd RVVSP2 Cable lub taub yuav tsum tau xaiv; Yog tias cov cuab yeej txhawb nqa peb cov qauv txheem, tom qab ntawd Stp -120 Ohuab yuav tsum tau xaiv.
