Description
1 in 4 8 out Industrial Photoelectric Isolation Repeater 4/8 Way RS485 Data Isolator 485 Hub RS485 Splitter
Product Description
RS-485 bus splitter hub (HUB) designed for industrial automation communication, solving RS-485 bus star structure networking and solving RS-485 large system requirements in complex electromagnetic field environment. Support The transmission rate is up to 115.2Kbps, the RS-485 interface uses opto-isolation technology, 600W lightning surge protection circuit, providing 1000V isolation voltage can effectively suppress
The lightning protection and ESD protection RS-485 working mode adopts the discriminating circuit to automatically sense the data flow direction, and automatically switch the enabling control circuit to easily solve the RS-485 transceiving conversion delay problem. The RS-485 interface transmission distance is greater than 3000 meters. Stable performance. Widely used in highway toll collection systems, road monitoring systems and power collection systems, it is a data interface conversion product with excellent performance and excellent price.
Features
Built-in photoelectric isolator and 600W surge protection.It can provide 2500V isolation voltage, which can effectively suppress lightning and ESD, and can effectively prevent lightning strikes and common ground interference. Built-in CPU processor automatically senses channel data flow direction.Automatically determine the channel status, automatically switch the enable control circuit, and easily solve the RS-485 transceiving conversion delay problem Using external power supply to provide wide voltage input.Powered by an external power supply switching power supply, safe and reliable, suitable for outdoor use, providing DC9-40V wide voltage input
