JPX-6021 is an RS-485 bus split hub (HUB) designed for industrial automation communication to solve the RS-485 bus star structure networking and solve the large RS-485 system requirements in the complex electromagnetic field environment. Transmission rate up to 115.2Kbps, RS-485 interface using optical isolation technology, 600W lightning surge protection circuit, providing 1000V isolation voltage can effectively suppress lightning and ESD protection. The identification circuit used in the RS-485 operation mode can automatically sense the direction of data flow, and automatically switch the enable control circuit to easily solve the problem of RS-485 transceiver and conversion delay. The RS-485 interface has a transmission distance of more than 3000 meters and stable performance. Widely used in high-speed, 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 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
*The built-in conversion processor automatically senses the channel data flow direction to automatically determine the channel status, automatically switches the enable control circuit, easily solves the problem of RS-485 transceiver conversion delay, and does not require jumper settings to achieve full-asynchronous half-duplex (RS-485) ) Mode conversion, plug and play.
* It adopts external power supply, provides wide voltage input and adopts external power supply switching power supply, which is safe and reliable. It is suitable for outdoor use and provides DC9-40V wide voltage input.
