5-Port Ring-Redundant Ethernet Switch, Industrial Aluminum Case, DIN-Rail-Mountable

Our ESW 405M ring-redundant Ethernet switch supports various ring topologies. The switch reads the header frame of each Ethernet packet, so it knows how and where to forward each packet. This capability provides redundancy and increases available bandwidth.

The rugged switch wall-mounts or DIN-mounts. It comes with a heavy-duty aluminum case (or choose the ESW 405P, which is functionally identical, but comes with an industrial plastic case). The ESW 405M includes five RJ-45 Ethernet ports, as well as an RS-232/485 port on a single RJ-45 connector, so you can communicate with both serial and Ethernet devices, or peripheral switches like our ESW 205P and ESW 208P. Power and output replays are connected via screw terminals. The switch has two independent DC power supplies for enhanced reliability.
