RS232/485to 4 port RS485 HUB

Model:SW4485Introduction:SW4485 is a RS-485 bus segmentation HUB, specially designed for conforming to RS-485’s large-scale system requirements under the complex electromagnetic environment. Its supporting transmission rates reach up to 115.2Kbps. It adopts transparent transmission in both directions. It can convert 1 RS-485 or RS-232 to 4 RS-485, or transparently transmit any intersected RS-485 signal to RS-485 or RS-232 on PC. Each RS-485 port of its lower position controller has reverse fault alarm and protection function, through which,the network reliability of RS-485 has been improved, and the maintenance time of network has been shortened efficiently. In order to ensure the safety and reliability of data communication, the RS-485 interfaces of SW4485 are supplied with 2KVAC isolation protection, 3 levels of ESD protection and 2 levels of electrostatic radiation protection; they can prevent lighting, common ground and radiated interference, safe and reliable, are suitable for outdoor application.SW4485 also provide star-RS485 BUS connection. Users can easily improve the RS-485 BUS structure, split network segment. You can design a unique and reliable RS-485 system through making reasonable use of SW4485.SW4485 adopts EMC protection design, supports wall-mounting and panel-mounting installation, and can be used at the harsh environment from -40℃ to 85℃.
