Industrial-grade isolated 4-channel RS485 hub repeater, DIN-rail mount, with wide baud rate range. One RS485 master port can be expanded to 4 RS485 slave ports. With isolation and relay capabilities.


Isolated 4-Ch RS485 Hub

Expands 4-ch RS485 ports via 1-ch RS485 master port, with isolation and relay

Features

RS485-HUB-4P is an industrial grade isolated RS485 hub that can expand 4-ch RS485 sub ports through 1-ch RS485 master port. It can realize signal 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...

Product Parameters

Basic functions

Can realize RS485 network relay, expansion and isolation functions


Connection Diagram

The isolated RS485 interface at the RS485 master port can be connected to the RS485 master control device. The interface can be connected to various RS485 slave devices, such as RS485 sensors, etc.


Note: Generally, RS485 wiring requires hand-in-hand connection. If a star connection with the master station as the center is unavoidable, this product can also be used to effectively isolate the interference between multiple RS485 connections.



Industrial isolation protection

Built-in optoelectronic isolation protection circuitry isolates RS485 master and slave devices, effectively protecting them from static electricity, lightning strikes, and surges between devices. Suitable for industrial environments requiring high reliability and safety.



Wide baud rate range

Supports 300bps ~ 460800bps wide baud rate communication range (adaptive)


Support rail installation

Supports 35mm standard rail, with rail clips for easy installation
