I-EIA RS485 iCable yaseTshayina yoNxibelelwano ngocingo lweSakhiwo seCable 120ohm yoNxibelelwano lweCable yeShishini yoMbane kunye noThumelo lweDatha
Isicelo
1. Intambo yenzelwe i-RS-485 i-Cable data communication kunye ne-automation systems, i-microprocessor kwisixhobo, njl njl. Iintambo ze-Multi-pair ziyafumaneka, zingasetyenziselwa ngokubanzi ukulawula inkqubo yokuvelisa, iinkqubo zekhompyutha ezizenzekelayo, ulawulo lwenkqubo oluzenzekelayo kunye nesicelo somlawuli. . I-RS485 ivumela amathontsi amaninzi kunye nobude bentambo ende, isantya esiphezulu, ngoko ke isetyenziswa rhoqo kwiindawo zoshishino kunye ne-automation. I-RS-485 iphinda isetyenziswe kwiindawo ezinkulu zethiyetha, ishishini leemoto, apho kukho ukungaqiniseki malunga nokuba yeyiphi ingxolo eya kuhlangabezana nayo ekugqibeleni. Iyakwazi ukuqaphela ikhewubhuli yomgama omde kwaye ikwaxhasa izixhobo ezininzi kwibhasi enye, inokufikelela uninzi lwezicelo ezifuna i-serial interface ekrelekrele. I-Rs-485 ikwabizwa ngokuqhelekileyo njenge-TIA-485 okanye i-EIA-485.
2 .Ukusebenza kakuhle kwi-electric and data transmission.
3. Umntu ngamnye ovavanyiweyo okanye obotshelelwe ngenkonkxa iyonke enkonkxiweyo ekhuselweyo inokwenza umqondiso kunye nokuphazamiseka komhla simahla.
4. Iingcingo zentsimbi ekhandiweyo zinomsebenzi olungileyo wokuxhathisa. Isetyenziswa kakhulu kuthumelo lomgama omde.
5. I-insulation ye-S-FPE yenza umhla kunye nonxibelelwano lwesignali lukhawuleze kwaye luzinze.
6. I-PE sheath inokufaneleka ukusetyenziswa ngaphandle.
