Schneider Electric TCSESM243F2CU0 Managed Switch

The Schneider Electric Telemecanique TCSESM243F2CU0 is a 22-port managed industrial Ethernet switch from the ConneXium family, built to deliver secure and reliable networking for PLC panels, manufacturing facilities, process automation, utility infrastructure, and other industrial networks. It combines 22 × 10/100BASE-TX copper ports with 2 × 100BASE-FX multimode SC fiber ports to support mixed copper and fiber deployments, and it supports Ethernet TCP/IP, SNMP, HTTP, HTTPS, SSH, LLDP, Telnet, SNTP, and MRP. Copper links reach up to 100 m per port (CAT5e), while fiber links extend up to 5 km with 50/125 μm multimode fiber. Power is 12–48 VDC and the unit is designed for DIN rail mounting with an IP20 protection rating. The switch is compatible with Modicon PLCs and broader Industrial Ethernet networks, making it suitable for factory automation, process control, power distribution, water treatment facilities, transportation systems, and machine automation where dependable industrial networking improves system availability, diagnostics, and communication reliability. It is offered as an OEM direct replacement, with Schneider Electric listing the Modicon Networking MCSESM243F4LG0 as the recommended contemporary substitute. This product is discontinued.
