RS-485 bus-division hub designed for RS-485 system used in complicated electromagnetic environments; It supports data communication rate up to 115.2KBPS; Photoelectric isolation technique is introduced to the RS-485 interface to prevent converter and device from lightning and surge voltage for ensuring the safe and reliable data communication; The built-in photoelectric isolator (an isolation voltage

as high as 2.5KVrms) and 600W surge suppressor can effectively suppress lightning and ESD and the grounding interference with each

RS-485 line; It uses external switching power supply for safety and reliability and is ideal for outdoor engineering applications; The

built-in discrimination circuit can automatically sense the direction of data flow and switch the enable control circuit to ensure the

automatic switch of transmit and receive in RS-485 mode; RS-485 is widely used in thruway toll system, road supervision system and electric power acquisition system as a high-performance and economical data interface converter; Short-circuit and open-circuit protection are provided for each port; Users can improve the RS-485 bus structure and divide bus segments conveniently for improved communication reliability; If lightning or faults occur then the failed segment will be isolated and make sure other segments can operate normally;

This feature significantly improves the reliability of existing RS-485 network and reduces maintanence interval; Reasonable use of RS-485 HUB can help to design a unique, highly reliable RS-485 system.
