LORDWORLD RS485-HUB-4P 4-Channel Isolated RS485 Hub Development Board

SKU CH-A2DZ-3BWGJ

Expands one RS485 master port into four isolated sub ports with optoelectronic protection, 300460800bps adaptive baud rate, and 35mm rail mounting for industrial networks

  • Expands one RS485 master port to four isolated sub ports for reliable network extension
  • Optoelectronic isolation protects against electrostatic discharge lightning and voltage surges in harsh environments
  • Self-adaptive baud rate from 300 to 460800 bps supports high-speed and low-speed devices
  • Mounts on standard 35 mm guide rails for quick installation in control cabinets
  • Suits data acquisition sensor networks automation IoT gateways and instrument monitoring applications

Industrial RS485 expansion hub

The LORDWORLD RS485-HUB-4P expands a single RS485 master port into four isolated sub ports for industrial communication networks and IoT devices. It is built for engineers and system integrators deploying sensor networks, data acquisition systems, or automation modules in harsh environments.

Baud rate and isolation limits

The hub supports self-adaptive communication at 300460800bps, covering both high-speed and low-speed RS485 devices. Optoelectronic isolation separates master and sub devices, protecting against electrostatic discharge, lightning, and voltage surges, but the interface remains bound to RS485 electrical characteristics and cabling constraints.

Rail-mount installation notes

A 35mm standard guide rail buckle allows quick mounting in control cabinets, IoT gateways, and industrial panels. Wiring mistakes such as reversed polarity or missing termination resistors on long bus runs are the most common cause of communication errors during commissioning.

この商品に関する質問

How do I choose between the 4-channel RS485 hub and other versions?

The RS485-HUB-4P provides exactly four isolated sub ports from a single master port, so select it when you need to split one RS485 line into four protected branches for sensors or controllers.

What does the 300460800 bps figure mean once the board is installed?

It means the hub auto-negotiates any standard RS485 speed from 300 bps up to 460800 bps, letting you mix slow legacy sensors and fast modern devices on the same four channels without manual configuration.

What interface standard does the hub use and what does it cap in practice?

The board uses RS485 with optoelectronic isolation on each of the four sub ports, capping each channel at the 460800 bps upper limit while protecting the master side from surges and ground loops.
