Schneider Electric TCSESU053FN0 Ethernet Switch

Schneider Electric’s ConneXium TCSESU053FN0 is an unmanaged Ethernet switch with five copper RJ-45 ports that delivers 10/100 Mbps Ethernet for straightforward device-to-network expansion in industrial control environments. Powered from a 24 V DC supply (9.6–32 V DC SELV), it occupies a compact 25 x 114 x 79 mm enclosure and weighs 0.113 kg, using a removable 3‑way power connector and drawing about 2.2 W. Each port features LED indicators for activity and speed (one LED per channel), alongside a power LED; the switch automatically negotiates 10/100 Mbps and supports auto MDI/MDX and polarity correction, making it easy to drop into existing ConneXium/Modicon networking topologies. Schneider Electric lists TCSESU053FN0 as discontinued as of March 15, 2022, with the recommended replacement MCSESU053FN0.
