LORDWORLD USB to 2CH RS485 Isolated Converter Industrial Grade Adapter FT2232HL 1.2km Development Board

SKU CH-MWGM-FMKXW

Adds two isolated RS485 channels over USB using an FT2232HL chip with 1.2 km range and rail-mount ABS case

  • Dual independent RS485 channels enable concurrent industrial communication
  • FT2232HL chip delivers fast stable data transfer across Win 10 11 8.1 7 Mac Linux Android
  • 2 km transmission distance reaches remote field devices reliably
  • 120 Ω jumper selectable termination simplifies bus configuration per site
  • Isolated power and signal with TVS fuse diodes protect equipment from surges

Two-Channel RS485 Over USB

This LORDWORLD development board adds two independent RS485 channels to any host with a USB port. The onboard FT2232HL chip handles concurrent communication on both channels without extra drivers on Win10, Win11, MacOS, Linux or Android. Industrial-grade isolation and a rail-mount ABS case make it suitable for factory floors, building automation and long-distance sensor networks.

Replaces Non-Isolated Single-Port Adapters

Moving from a basic USB-to-RS485 dongle to this unit adds channel concurrency, 120R termination jumpers and full galvanic isolation on power and data lines. The jump is worth it when you must run two separate buses simultaneously or when lightning and ground-loop transients threaten equipment uptime. Built-in TVS diodes and a self-recovery fuse protect both the host and the field devices without external circuitry.

Sustained Industrial Operation

Under continuous load the isolated DC-DC supply maintains stable voltage to the RS485 transceivers while digital isolators keep signal integrity intact. The 1.2km rated distance holds because the 120R termination is jumper-selectable per channel, preventing reflections on long cable runs. Three status LEDs let operators verify power and traffic at a glance without software probes.

Questions about this item

What rail size does the ABS case mount on?

The industrial-grade ABS case is designed for standard DIN-rail mounting, letting you snap the board onto a control-cabinet rail without extra brackets.

Which jumper sets the 120R termination on each RS485 channel?

A 3-pin jumper per channel enables or disables the built-in 120R terminal resistor; move the shunt to the ON position before powering the bus to match line impedance.

When should the onboard self-recovery fuse be checked or replaced?

The fuse resets automatically after an over-current event; if the power LED stays off after the fault clears, the board needs service because the fuse has permanently opened.
