LORDWORLD

LORDWORLD USB to 4CH RS485 Converter Module

SKU CH-MSK5-E1ZBP

Adds four independent RS485 channels via USB with 1200 to 460800 bps speed and 1.2 km range

  • Four independent RS485 channels from one USB port
  • Surge protection with onboard TVS and resettable fuse
  • Configurable 120R termination via DIP switch per channel
  • Reliable data rates from 1200 to 460800 bps
  • Communication distance up to 1.2 km over twisted pair

Four-channel RS485 expansion

The LORDWORLD module adds four independent RS485 ports to a single USB connection, letting industrial equipment, sensors or automation nodes communicate concurrently without sharing a bus. Each channel operates separately so data from one device never blocks another.

Replaces single-port USB-RS485 adapters

When a project needs more than one RS485 link, this unit removes the need for multiple dongles or a powered hub, saving desk space and USB ports. The upgrade makes sense once the device count exceeds one or when cable runs must stay isolated per channel.

Sustained industrial operation

Onboard TVS diodes, a resettable fuse and protection diodes clamp surges and over-current events that appear during long cable runs or lightning exposure. The 120R termination resistors are DIP-switch selectable per channel, keeping signal integrity stable over distances up to 1.2 km at speeds from 1200 to 460800 bps. The aluminium CNC case dissipates heat without fans, so the converter maintains throughput during continuous polling cycles.

Questions about this item

What physical mounting does the aluminium alloy case provide?

The CNC-machined aluminium alloy case with oxidation dull-polish surface is solid and durable for panel or DIN-rail mounting in industrial cabinets.

How are the four RS485 channels installed and which step is often missed?

Connect each channel to the onboard terminal blocks, then set the DIP switch to enable or disable the 120R termination resistors per channel — forgetting the DIP switch is the common error.

What maintenance will the onboard protection components need over time?

The resettable fuse and protection diodes self-recover after over-current or over-voltage events; the TVS suppressor handles surge spikes without replacement under normal 1.2km line operation.
