Isolated typeRS485ERepeater is a kind of high power industrial grade RS485 signal amplifier. Products can automatically sense data flow direction and communication baud rate, does not require any control or handshaking signals and to ensure the transparent data transmission. Equipment power supply and communication signal is completely isolated, at the same time with surge protection, electrostatic protection and other measures. Has the characteristics of long distance transmission, high speed, stable and reliable performance. Widely used in attendance machine, IC card charging system, automation control, access control system, parking lot, dining service system, highway toll system.
1.industrial design, communication is completely isolated, stable and reliable performance,Transmission ratemostUp to 500Kbps; 2.built-in high-quality DC/DC power module, realize the electrical isolation between ports; 3.Support multi machine communicationThat can connect up to 128 nodes, far transmission distance of 1200 meters; 4.data flow automatic control technology, automatic control and data transmission; 5.multiple protective measures:ESD 15KV positive and negative protectionTVS, 600W dual 2.5KV communication isolation protection; 6.the power supply of wide range of 9-36VDC, and has anti polarity protection;
RS485E equipment suitable for the recommended value in the long-term stable operation; equipment in the limit value of work will not damage, but may result in performance degradation; any time do not exceed the limit value, otherwise it may damage the equipment!
