LORDWORLD

LORDWORLD 4-Ch RS485 to RJ45 Ethernet Serial Server

SKU CH-Y5K4-AA555

Four independent RS485 channels connect to Ethernet for serial server, Modbus gateway, MQTT gateway and JSON conversion with screw-terminal power and wall or rail mounting

  • Four RS485 channels operate independently for simultaneous data transmission
  • Combines serial server Modbus gateway MQTT gateway and JSON conversion in one unit
  • Screw terminal power input provides stable industrial connections
  • Wall-mount and rail-mount enclosure enables quick deployment in cabinets
  • Industrial isolated design protects equipment from electrical interference

Four-Channel RS485 Ethernet Gateway

This LORDWORLD device converts four independent RS485 channels to a single RJ45 Ethernet link. Each channel operates without interfering with the others, making it suited for industrial automation and IoT edge deployments. The module functions as a serial server, Modbus gateway, MQTT gateway and RS485-to-JSON translator in one unit.

Combined Protocol Support

Bundled firmware merges serial server, Modbus gateway, MQTT gateway and JSON conversion roles, so separate converters are not required. This reduces cabinet space and configuration effort when linking legacy RS485 sensors or actuators to modern Ethernet networks. The multi-protocol stack handles bi-directional data flow across all four channels simultaneously.

Wall And Rail Mount Enclosure

A screw-terminal power input secures wiring against vibration in harsh environments. The case supports both wall-mount and DIN-rail mounting for quick deployment and future expansion. Build quality targets industrial settings where reliable, long-term operation matters more than compact dimensions.

Questions about this item

What maintenance or replacement will the four RS485 channels need later?

The unit has no user-replaceable parts listed; keep screw terminals tight and protect the RJ45 port from dust.

What limit appears first when all four channels run continuously?

Each RS485 channel operates independently, so throughput per channel is the first bottleneck.

How much noise and heat does the module produce in an enclosure all day?

Passive metal case runs silent; warmth stays low because power draw is minimal.
