8-Port RS485 HUB 8-Channel Splitter Sharer Industrial Grade Optically Isolated Repeater Guide Rail Collector Distributor Divide
8-way hub is an RS-485 line split hub (HUB) designed specifically for industrial automation communications, which addresses RS-485 bus star structure networking, and requirements of RS485 large systems in complex electromagnetic fields. Supports transmission rates up to 115.2KBPS, and RS-485 interface uses isolation technology. A 600W surge protection circuit provides 1000V isolation voltage to effectively suppress and ESD protection.
discrimination circuit used in RS-485 operating mode can automatically sense direction of data flow, and automatically switch enabling circuit, easily solving RS-485 transceiver conversion delay problem. RS-485 interface has a transmission distance greater than 3000 meters and stable performance. Widely used in highway toll collection systems, road monitoring systems, and power acquisition systems, it is a data interface conversion product with excellent performance and excellent .
