Power On – The Hub

This Modbus hub allows the Eaton SC300 controller to add an ‘out of band’ RS485 network to communicate with up to 4 Modbus Communications buses supporting around 10 Modbus devices per port.

The SW4485I-P is a RS-485 HUB designed for noisy industrial environments. 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 a 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 2 KVAC 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.

The SW4485I-P also comes with RS-485 bus star connection. Users can easily improve RS-485 bus structure and divide the network segment. Proper utilisation of SW4485I-P (12/48 VDC) can help design a unique and reliable RS-485 system. SW4485I-P (12 / 48 VDC) adopts EMC protection and supports DIN-rail installation, allowing it to be used reliably in severe environments at a temperature of -40~75 C.
