Schneider Electric MCSESU083FN0 Modicon 8-Port Unmanaged Switch DIN Rail Industrial Ethernet Switch

The Schneider Electric MCSESU083FN0 is a Modicon Networking unmanaged Ethernet switch with 8 copper 10/100BASE-TX ports for plug-and-play connectivity. It needs no configuration, draws 1.5 W from a 12...24 V DC supply, and mounts on a DIN rail at 38 x 102 x 79 mm and 0.15 kg for small, isolated network segments.

Applications

Schneider Electric lists the MCSESU083FN0's shielded connectors as suited to small, isolated networks with light traffic and low complexity — a single machine cell or local I/O group rather than a plant backbone. Its 8 copper ports suit a panel with more field devices than the 5-port variant covers, linking drives, I/O blocks and an HMI to a controller without the cost or configuration overhead of a managed switch.

Selection Notes

The MCSESU083FN0 is the highest copper-port-count, no-fiber unmanaged switch in the Modicon line — pick it over the 5-port MCSESU053FN0 when more field devices need to connect locally, and over the fiber-equipped 6-port variants when every device sits within standard 100 m copper reach so no fiber uplink is needed. At 38 mm wide it is slightly larger than the 5-port unit to fit the extra 3 ports, while staying a plug-and-play device with no configuration or management overhead.
