We are proud to announce the release of our newest product, the RS485 TO ETH (B) Industrial Rail-mounted Serial to Ethernet Server. This device is designed for industrial environments and combines multiple functions into one compact module, including serial server, Modbus gateway, MQTT gateway, RS485 to JSON, and more.

Featuring an RS485 port and Ethernet port (POE function optional), the RS485 TO ETH (B) uses screw terminals for power input and is designed with a rail-mount case, making it easy to install in tight spaces. It is ideal for applications such as data acquisition, IoT gateway, safety and security IoT, and intelligent instrument monitoring.


Features at a Glance

  • Serial server, Modbus Gateway, MQTT Gateway
  • Bi-directional transparent data transmission between RS485 and Ethernet
  • RS485 port x 1, Ethernet port x 1
  • 9 ~ 24V DC screw terminal power input
  • Rail-mount case design, small in size, easy to install
  • Isolation Protection: N/C for product RS485 TO ETH (B); Power isolation, Signal isolation for product RS485 TO POE ETH (B)
