Description
Industrial Isolated 8-Channel RS485 Hub
Extends 8 RS485 channels via 1 master RS485 port, with isolation and relay. DIN rail mount, wide baud rate range.
Isolated 8-Channel RS485 Hub
Extends 8 slave RS485 ports via 1 master RS485 port — with isolation and relay
Features Overview
The RS485-HUB-8P is an industrial isolated RS485 hub that extends 8 slave RS485 ports via 1 master RS485 port. The device implements RS485 network relay, expansion, and isolation functions. Power is connected via screw terminals. The DIN rail mount enclosure ensures convenient installation and affordability. Suitable for data acquisition, IoT gateways, security systems, and intelligent instrument monitoring.
Technical Specifications
| Interface Standard | Compliant with RS485 standard |
|---|---|
| Physical Interface | RS485 screw terminals |
| Baud Rate | 300–460,800 bps (adaptive) |
| Supported Nodes | Up to 32 nodes per RS485 port |
| Communication Distance | 1200 m (at 9600 bps); distance decreases with increasing speed |
| Operating Mode | RS485 two-wire (A, B), half-duplex transparent transmission |
| Power Supply | DC 9–24 V |
| Operating Temperature | -45 … +85 °C |
| Environmental Humidity | < 95% RH |
| Transmission Medium | Ordinary parallel cables / twisted pair |
Main Function
Supports RS485 network relay, expansion, and isolation functions.
Connection Diagram
The isolated master RS485 port connects to the RS485 host device, and the 8 expanded isolated RS485 ports connect to various RS485 slave devices, such as RS485 sensors.
Normally, RS485 requires serial (daisy-chain) connection. If a star topology (master station in the center) is needed, this RS485 hub effectively isolates mutual interference between multiple RS485 devices.
Industrial Protection & Isolation
Built-in photoelectric isolation circuit effectively separates master and slave RS485 devices, preventing damage due to ground potential differences. Provides protection against electrostatic discharge, lightning, and overvoltage — suitable for industrial environments with increased demands for reliability and safety.
Wide Baud Rate Range
Supports a wide range of baud rates: 300–460,800 bps (adaptive mode).
DIN Rail Mount
Supports standard 35 mm DIN rail. Equipped with a clip for rail mounting — easy to install.
