Product Description  


  1. Product overviews

    8 channel rs485hub is an internal a pair of microprocessor, continuous work designed to solve complex as a bio-energy field environment rs -485 a system for the design of the rs -485 bus split the hub. the product support for the transmission rate highest 115. 2kbps data communications, to ensure the safe, isolation -485 interface by photovoltaic technology to prevent the waves into converters and equipment, the built-in photoelectric separator and 1500w the waves, the protection circuit, Can provide 2500v isolation voltage, can effectively restrain electrostatic discharge of lightning and the same time, they can effectively prevent and a total of course, the supply of a switch power supply of safe and reliable, and very suitable for an application in engineering.

    Built-in intelligence data flows, the microprocessor distinction circuit can automatically perception data flow direction, and automatically switches to control circuit, easy to solve the rs -485 complex issue. when latency rs -485 interface than 3000 meters at a distance, performance and stability. for the charge system, road supervisory system and electricity collection system is a performance excellence safe and reliable data interface the product.

    8 channel rs -485 hub with a star rs -485 bus connects. ports are having a short circuit protection and display and   isolation 2500v, users can improve the structure, rs -485 separate segments to improve communications reliability. when   or equipment failure as a result, the segment will be taken to ensure the normal work of other segments. the performance of the existing network rs -485, effectively closed the network maintenance. Reasonable use 8 channel rs -485 hub can help you to design own reliability, rs -485 system.
