Overview

Introduction

RS485-HUB-8P is an industrial grade isolated RS485 hub that can expand 8-ch RS485 slave ports through 1-ch RS485 master port and can realize relay, extension, and isolation functions of RS485 network, with screw terminal for power input. Rail-mount case design, easy to install, and cost-effective. It is suitable for applications like data acquisition, IoT gateway, safety & security IoT, and intelligent instrument monitoring...

Extension

When the master RS485 device needs to connect 8x RS485 slaves in a star connection, connect the master to the RS485-HUB-8P master port and the slaves to the RS485-HUB-8P slave port. It can prevent interference between RS485 and isolate effectively.

Isolation

By connecting one end of the RS485 to the RS485 master port and the other end to any RS485 slave port, the RS485 cable is effectively isolated and protected from lightning strikes and interference. The other end of RS485 is effectively protected from damage by high voltage and strong current.

Relay

When the RS485 cable exceeds a long distance such as 1200 meters, the signal will be attenuated and interference will increase. By using RS485-HUB-8P, the communication distance can be extended.
