RS485 armored communication cable

RS485 armored communication cableRS485 armored communication cableRS485Communication cables can use the method of adding relays to amplify signals during transmission. Eight relays can be added, which means theoreticallyRS485The transmission distance can reach9.6Kilometers.Interface signal level ratioRS-232-CIf it is lowered, it is less likely to damage the chip of the interface circuit, And this level is related toTTLLevel compatibility, convenient for compatibility withTTLCircuit connection.

3. RS485Communication cable usage environmentIn low-speed, short distance, and interference free situations, ordinary twisted pair cables can be used. In high-speed and long-distance transmission, impedance matching (usually120ΩofRS485Special cables should also use armored twisted pair shielded cables in harsh interference environments. in useRS485When interfacing, for specific transmission linesRS485The cable length allowed for data signal transmission from the interface to the load is inversely proportional to the baud rate of the signal transmission. This length of data is mainly affected by signal distortion and noise. In theory, the communication rate is100KbpsAt and below,RS485The transmission distance can reach1200However, the transmission distance in practical applications also varies due to the transmission characteristics of chips and cables.RS485Communication cables can use the method of adding relays to amplify signals during transmission. Eight relays can be added, which means theoreticallyRS485The transmission distance can reach9.6Kilometers. If long-distance transmission is really needed, optical fiber can be used as the propagation medium, and a photoelectric converter can be added at each transmitting and receiving end. The transmission distance of multimode optical fiber is5~10Kilometers, while using single-mode fiber can reach50The propagation distance of kilometers.RS485Cable typeOrdinary twisted pair shielded cableSTP-120Ωfor RS485 & CAN）one pair 18 AWGCable outer diameter8.2mmabout.
