RS485通信電纜ASTP-120現(xiàn)場(chǎng)總線規(guī)格

【資料簡介】

RS485通信電纜ASTP-120現(xiàn)場(chǎng)總線規(guī)格          

485 數(shù)據(jù)電纜可以在2.5MB/s的速度下傳送1200 米,用于復(fù)雜的樓宇自控、工業(yè)控制網(wǎng)絡(luò)、電力自動(dòng)化等通訊網(wǎng)絡(luò)。
RS-485 data cable is used for multi point communication. Many devices can be connected by a signal cable. Just as the previous Ethernet connected to a coaxial line. RS-485 data cable can be transmitted at the speed of 2.5MB/s 1200 meters, for complex building automation, industrial control network, power automation and other communication networks.
