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

Interface standards	Compliant with RS485 standards
Physical interface	RS485 terminal blocks
Communication rate	300bps ~ 460800bps baud rate (auto-adaptive)
Support points	Each RS485 port supports up to 32 nodes
Communication distance	1200m (9600bps), the higher the communication rate, the shorter the distance
How it works	RS485 two-wire (A, B), half-duplex transparent transmission
Supply voltage	DC 7V ~ 36V
Operating temperature	-45℃ ~ +85℃
Ambient humidity	< 95%RH
transmission medium	Ordinary parallel wire / twisted pair wire

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
