Intengo ephansi kakhulu ye-Fiber Optic Cable - Rs485 esontekile 2 core 3 core 4 cores 20AWG 22AWG 18AWG - AIXTON

Imininingwane RS-485 iyindinganiso kagesi kuphela. Ngokungafani namazinga okusebenzelana okugcwele, achaza ukucaciswa kokusebenza, komshini, kanye nogesi, i-RS-485 ichaza kuphela izici zikagesi zabashayeli nabamukeli abangasetshenziswa ukuze kusetshenziswe ulayini wokudlulisela we-multidrop olinganiselayo. Leli zinga, nokho, kuhloswe ngalo ukuthi kubhekiselwe kumazinga aphezulu, njenge-DL/T645, isibonelo, echaza umthetho olandelwayo wokuxhumana. kumamitha wamandla kagesi e-China, ecacisa i-RS-485 njengezinga elijwayelekile lesendlalelo esibonakalayo. Izici 1.Ukumelana nokushisa, ukumelana nelangabi 2.ukusebenza kahle kokufakwa kwamakhemikhali, ukusebenza kwamakhemikhali okuzinzile 3.ukusebenza kahle kokudlulisa ngenxa yokusetshenziswa kwe-polyethylene yekhwalithi ephezulu yokuvikela ikhebula elilukiwe 4.Ukumelana ngempumelelo nokuphazanyiswa yizibuthe ngenxa yokusetshenziswa Kwenziwe uhlobo olusha lwe ucwecwe lwe-aluminium, ungqimba oluphindwe kabili olulukiwe lwe-mesh yethusi. Izicelo RS-485 amasignali asetshenziswa anhlobonhlobo computer kanye ezishintshayo izinhlelo. Ohlelweni lwekhompiyutha, i-SCSI-2 ne-SCSI-3 ingasebenzisa lokhu kucaciswa ukuze kuqalise isendlalelo esibonakalayo sokudlulisa idatha phakathi kwesilawuli nedrayivu yediski. I-RS-485 isetshenziselwa ukuxhumana kwedatha enesivinini esiphansi emabhasini ezimoto zendiza yezindiza. Idinga izintambo ezincane futhi ingabelana ngezintambo phakathi kwezihlalo eziningi, kwehlise isisindo. Amapharamitha Imodeli NO OD(MM) Ubude (m) Ubukhulu bokumelana kukakhondatha ku-20℃(Ω/KM) Isilinganiso esincane sokumelana komqhubi ku-70℃(Ω/KM) RS-485 2*0.5 5.5 100/200 39 0.012 RS-485 2* 0.75 6.0 100/200 26 0.010 RS-485 2*1.0 6.6 100/200 19.5 0.010 RS-485 2*1.5 7.5 100/200 13.3 RS 0.005 8 0.008 RS-485 3* 0.5 5.8 100/200 39 0.012 RS-485 3*0.75 6.3 100/200 26 0.010 Izithombe
