(English) IT-SC4485I-PSW

(English)

IT-SC4485I-PSW (12/48VDC) is RS-485 HUB is designed for RS-485 system in complicated electromagnetic environment. It supports a transmission rate up to 115.2KBPS, and adopts two-way transparent transmission, which allows one RS-485 bus or one RS-232 bus to be divided into 4 RS-485 buses, or any divided RS-485 signal to be transparently transmitted to host computer RS-485 or RS-232 hub. Each RS-485 port of slave computer is provided with reverse connection alarm and protection function, with which the reliability of existing RS-485 network is greatly improved, effectively reducing the network maintenance time. To ensure the security and reliability of data communication, the RS-485 ports are provided with 2KVAC isolation protection, level-4 electrostatic protection and level-2 radiated susceptibility, effectively preventing surge current, common ground and radiated interference, making the hub safe and reliable and suitable for outdoor application. IT-SC4485I-PSW (12/48VDC) also comes with RS-485 bus star connection. Users can easily improve RS-485 bus structure and divide the network segment. Proper utilization of IT-SC4485I-PSW (12/48VDC) can help design a unique and reliable RS-485 system. IT-SC4485I-PSW (12/48VDC) adopts EMC protection and supports DIN-rail installation, allowing it to be used reliably in severe environment at a temperature of -40℃~75℃.
