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.



Electric connection: 3 / 14-bit wiring terminal for both DC and RS-485 interface;



Transmission media: twisted-pair cable or shielded cable;



Operation mode: asynchronous half-duplex;



Power supply: DC 9~36V / 350mA;



Signal indication: 7 signal indicators - power (PWR), transmission (TD), receive (RD), 4-CH receiving indicator lights (485-1~485-4);



Isolation voltage: continuous 2.5KVrms / DC 500V isolation DC/DC module; 



Data rate: 115.2K~300BPS;



Protection class: +/-15KV ESD protection for RS-232 interface;



600W lightning strike and surge protection for each RS-485 line;



Communication distance: 0~5km (115.2K~300bps);



Working environment: -40~85'C / humidity: 5%~95%.
