RS485 Tswj Cable Taw Qhia

RS485 yog tus qauv kev sib txuas lus uas feem ntau siv rau kev tswj hwm kev lag luam thiab kev siv automation. RS485 tswj cables yog siv los txuas cov khoom siv hauv RS485 network. Qee cov ntsiab lus tseem ceeb txog RS485 tswj cables:

• RS485 siv cov kev taw qhia sib txawv ntawm ob lub xov hlau - cov ntaub ntawv + xaim thiab cov ntaub ntawv- xaim. Qhov no muab cov suab nrov tiv thaiv thiab muaj peev xwm khiav cov kab ntev ntev.

• RS485 cables feem ntau muaj tsawg kawg yog ob tug twisted khub xov hlau rau cov ntaub ntawv + thiab cov ntaub ntawv- , thiab tej zaum ib tug xaiv av xaim. Lub twisting pab txo cov kev cuam tshuam electromagnetic (EMI).

• RS485 siv ntau lub tsheb npav topology, txhais tau tias ntau yam khoom siv tuaj yeem txuas rau tib lub cable. Txhua lub cuab yeej muaj qhov chaw nyob tshwj xeeb.

• RS485 tuaj yeem khiav ntawm cov ntaub ntawv tus nqi ntawm 1200 bps mus txog 10 Mbps lossis siab dua, nyob ntawm qhov ntev cable thiab lub peev xwm ntawm cov cuab yeej.

• RS485 tso cai rau cable ntev txog 1200 meters (4000 ko taw) ntawm cov ntaub ntawv qis dua, ua rau nws tsim nyog rau kev lag luam thiab kev siv lub tsev automation.

• RS485 siv qhov hluav taws xob tsawg tsawg ntawm ± 7V rau '1' thiab '0' teeb liab. Qhov no ua rau kev siv hluav taws xob tsawg.

• Kev kos tam sim no hauv RS485 network yog nyob rau hauv milliamp ntau (20-40 mA siab tshaj). Qhov no tso cai rau ntau yam khoom siv los qhia tib lub cable.

• RS485 cables yog tsim los tiv thaiv ib puag ncig tej yam kev mob nyob rau hauv industrial chaw, nrog shielded, ruggedized cables muaj.

Yog li hauv cov ntsiab lus, RS485 tswj cov kab hluav taws xob ua kom muaj zog, sib txawv ntawm kev sib txuas lus ntawm ntau yam khoom siv ntev ntev ntawm cov ntaub ntawv qis. Qhov no ua rau RS485 haum rau kev tswj hwm kev lag luam thiab kev siv automation uas tsis muaj suab nrov tiv thaiv, cable ntev thiab ntau-tej topology yog qhov tseem ceeb.
