EDS-405 Redundant Ring Ethernet Switches

Moxa EDS-405 Redundant Ring Industrial Ethernet Switches

EtherDevice™ Switch EDS-405 Series

- Cost-effective, Plug-n-Play Ethernet Media Redundancy Solution

The MOXA EDS-405 Series—the newest generation of EtherDevice™ Switch—includes 2 models: EDS-405 and EDS-405-MM. The EDS-405 Series consists of 5-port Ethernet switches specially designed for industrial automation and control systems, and also comes with plug-n-play MOXA Turbo Ring, which is used to establish an Ethernet redundant ring topology. Turbo Ring can automatically transmit over a redundant path segment in less than 300 ms, increasing the reliability of your system.

The built-in relay output function helps you monitor each port's link status, each power input's status, and the health of the Turbo Ring topology, allowing your maintenance engineers to react promptly to emergency situations.

The redundant dual DC power inputs help insure non-stop operation, and flexible installation options by DIN-Rail or wall mounting make it easy for you to fit EDS-405 into any workspace.


  • Plug-n-Play, Ring Redundancy solution (recovery time < 300 ms)
  • Power failure and port break by relay output alarm
  • 10/100M, Full/Half-Duplex, MDI/MDI-X auto-sensing
  • Redundant dual DC power inputs
  • DIN-Rail or panel mounting ability

The Moxa Turbo Ring Technology
"MOXA Turbo Ring" is the state of the art feature that is developed by Moxa exclusively for MOXA industrial Ethernet switches. It is used to establish an Ethernet redundant ring topology.

If one segment is broken, Turbo Ring will automatically transmit over a redundant path segment in less than 300 ms, allowing your industrial automation and control applications to run non-stop.
