8-way RS-485 HUB hubOpto-isolated lightning protectionStable and reliable industrial quality1-way RS-485 to 8-channel RS-485 hubproduct description:QZ-6081 is a RS-485 bus split hub (HUB) designed for industrial automation communication and solving the RS-485 bus star structure networking to solve the RS-485 large system requirements in the complex electromagnetic field environment. Supports transmission rates of up to 115.2Kbps. The RS-485 interface uses opto-isolation technology. The 600W lightning surge protection circuit provides 1000V isolation voltage to effectively suppress lightning and ESD protection.
The discriminating circuit adopted in the RS-485 working mode can automatically sense the direction of data flow and automatically switch the enable control circuit to easily solve the problem of RS-485 transceiving and conversion delay. RS-485 interface transmission distance is more than 3000 meters, stable performance, widely used in highway toll system, road monitoring system and power acquisition system, it is a data interface conversion product with excellent performance and excellent price.Features:Built-in photoelectric isolator and 600W surge protection power supply can provide 2500V isolation voltage, can effectively suppress lightning and ESD, and can effectively prevent lightning and common ground interferenceThe built-in CPU processor automatically senses the channel data flow direction to automatically determine the channel status, automatically switches the enable control circuit, and easily solves the problem of RS-485 transceiving conversion delay.External power supply, wide voltage input, external power supply, safe and reliable, suitable for outdoor use, DC9-40V wide voltage input
