I-EIA RS485 Ikhebula Yase-China Yokuxhumana Intambo Yokwakha Ikhebula 120ohm Ikhebula Lemboni Yokuxhumana Yokudluliswa kukagesi kanye nedatha
Isicelo
1. Ikhebula lenzelwe i-RS-485 Cable data communication namasistimu ezishintshayo, i-microprocessor ukuya kudivayisi, njll. Izintambo ezinamapheya amaningi ziyatholakala, zingase zisetshenziselwe kabanzi ukulawula inqubo yokukhiqiza, amasistimu wokuzenzakalela kwekhompiyutha, isilawuli senqubo esizenzakalelayo kanye nohlelo lokusebenza lwesilawuli. . I-RS485 ivumela amaconsi amaningi kanye nobude bekhebula elide, isivinini esikhulu, ngakho-ke ibuye isetshenziswe njalo ezimbonini nasezindaweni ezishintshayo. I-RS-485 isetshenziswa nasezindaweni zeshashalazi ezinezikhala ezinkulu, imboni yezimoto, lapho kunokungaqiniseki ngokuthi yimuphi umsindo ozohlangatshezwana nawo ekupheleni kwesicelo. Ingakwazi ukubona ikhebula lebanga elide futhi iphinde isekele amadivaysi amaningi ebhasini elifanayo, ingafinyelela izinhlelo zokusebenza eziningi ezidinga isixhumi esibonakalayo esihlakaniphile.Kuwuhlobo lokucaciswa kwezimboni. I-Rs-485 evame ukubizwa ngokuthi i-TIA-485 noma i-EIA-485.
2 .Ukusebenza kahle kugesi kanye nokudluliswa kwedatha.
3. Okusikiwe okukodwa noma okuhlanganisiwe kwethusi okuhlanganisiwe kungenza isignali kanye nokuphazamiseka kwedethi kukhululeke.
4. I-galvanized steel wire inomsebenzi omuhle wokumelana nokuqina. Isetshenziswa kabanzi ekudluliselweni kwebanga elide.
5. I-insulation ye-S-FPE yenza idethi nesiginali yokuxhumana ngocingo kusheshe futhi kuzinze.
6. I-PE sheath ingafaneleka ukusetshenziswa ngaphandle.
