ماژول مبدل پروتکل صنعتی RS485 به TTL UART دارای برد بالا تا کیلومتر، تداخل پایین، مناسب جهت راه اندازی پروژه های صنعتی ، میکروکنترلر و مینی کامیپوترها می باشد.
*3.3V with 5.0V power supply perfectly compatible.
*3.3V with 5.0V signal perfectly compatible.
*Operating temperature : -40 ℃ ~ + 85 ℃.
*Size:42.8mm * 15.22mm * 0.8mm .
Features:
*With RXD, TXD signal lights.
*Transmission distance up to kilometers.
*Absolute adopts imported chip, industrial design, strong anti-interference ability, at the same time more effective lightning protection design, 485 can be used in industrial field and field under the harsh environment. （Using 850 meters with 2 * 1.5 cable to do the test, it is recommended to be used within the 800 meters, more than 800 m, please add extra repeaters).
*Use half hole process design, thickness of 0.8 mm, can be used easily as a child motherboard, also can be used welding terminals.
*With a standard 2.54 spacing design, convenient your secondary development.
*With 120 European match resistance, can make short sub R0 can match resistance, proposed the short answer the long distance transport.
*Support multiple machine communications, allowed to take in up to 128 devices on the bus.
*This module can be hot plug, there will be no other 485 chip hot plug phenomenon of signal switch to death.
*Large area laying copper, preventing signal interference.
