EIA RS485 Cable Tuam Tshoj Kev Sib Txuas Lus Cable Tsev Hlau 120ohm Kev Sib Txuas Lus Muaj Cable rau Hluav Taws Xob Thiab Cov Ntaub Ntawv Xauv
Daim ntawv thov
1. Lub cable yog tsim los rau RS-485 Cable cov ntaub ntawv kev sib txuas lus thiab automation systems, microprocessor rau ntaus ntawv, thiab lwm yam. Multi-pair cables muaj, lawv yuav tau lug siv rau ntau lawm txheej txheem tswj, computer automation systems, tsis siv neeg txheej txheem tswj thiab xws li daim ntawv thov . RS485 tso cai rau ntau qhov tee thiab ntev cable ntev, kev kub ceev, yog li nws kuj nquag siv hauv kev lag luam thiab automation teb. RS-485 kuj tseem siv nyob rau hauv qhov chaw ua yeeb yam loj, kev lag luam tsheb, qhov twg tsis paub meej txog dab tsi lub suab nrov yuav ntsib nyob rau hauv daim ntawv thov kawg. Nws tuaj yeem paub cov cabling ntev thiab tseem txhawb nqa ntau yam khoom siv ntawm tib lub npav, tuaj yeem ua tiav cov ntawv thov feem ntau uas yuav tsum tau muaj kev sib txuas sib txuas ntse. Rs-485 kuj feem ntau hu ua TIA-485 lossis EIA-485.
2 .Kev ua tau zoo ntawm hluav taws xob thiab cov ntaub ntawv xa mus.
3. Kev tshuaj xyuas tus kheej lossis tag nrho cov tinned tooj liab braided shielded tuaj yeem ua rau lub teeb liab thiab hnub cuam tshuam tsis pub dawb.
4. Galvanized steel hlau muaj qhov zoo tensile tsis kam ua haujlwm. Dav siv nyob rau hauv kev sib kis mus ntev.
5. Cov rwb thaiv tsev S-FPE ua rau hnub tim thiab teeb liab kev sib txuas lus ceev thiab ruaj khov.
6. PE sheath yuav haum rau siv sab nraum zoov.
