Opto-isolated lightning protectionStable and reliable quality of this level1-way RS-232/RS-485 to 4-way RS-485 hubproduct description:QZ-6040 is a RS-485 bus split hub (HUB) designed for industrial automation communication and solving RS-485 bus star structure networking to solve the RS-485 large system requirements in 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 a 2500V 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 greater than 3000 meters, stable performance # widely used in highway toll systems, road monitoring systems and power acquisition systems, is a high performance, excellent price data interface conversion products.Features: Built-in optical isolator and 600W surge protection circuit can provide 2500V isolation voltage, can effectively suppress lightning and ESD, and can effectively prevent lightning and common ground interference Built-in CPU processor automatically senses the channel data flow direction to automatically determine the channel status, automatically switch the enable control circuit, and easily solve the RS-48S send and receive conversion delay problemUsing external power supply, providing wide voltage input using external power supply switching power supply, safe and reliable, suitable for outdoor, providing DC9-40V wide voltage input * Supports 1 RS-232/485 to 4 RS-485* Adopt high-performance transient voltage suppression tube* Built-in DC-DC power isolation module* Communication using high-speed optocoupler isolation protection* Baud rate adaptation* Asynchronous half duplex, two-way communication*9-40VDC wide voltage input* Rail installation is quick and easyTerminal location definition:V-power negative
