TCSESM043F2CU0

Spare Part Number

PNTCSESM043F2CU0

Product Information:

The TCSESM043F2CU0 is a Schneider Electric ConneXium series industrial Ethernet managed switch. As core network hardware conforming to Schneider's "Transparent Ready" philosophy, it is primarily deployed in control cabinets in factory workshops. This module supports highly deterministic and secure industrial-grade TCP/IP network interconnection and data exchange between PLC processors, HMI touchscreens, and various distributed I/O devices.

In terms of hardware configuration and network logic, the TCSESM043F2CU0 is equipped with two 10/100Base-TX shielded RJ45 copper Ethernet ports and two 100Base-FX multimode duplex SC fiber optic interfaces (MM), meeting the needs of long-distance, interference-resistant hybrid cabling.

The TCSESM043F2CU0 integrates rich Layer 2 management functions, supports network configuration via a built-in web server, and can build a redundant single-ring network of up to 50 switches via RSTP (Rapid Spanning Tree Protocol). It also features VLAN segmentation, IGMP Snooping multicast filtering, FDR (Faulty Device Replacement), and MAC address-based port hardening security protection technologies.

Information

Overview Manuals Network & Performance Logic Modern Upgrade Path

Features:

  • MEthernet TCP/IP managed switch - ConneXium -2TX/2FX - multimode
  • Features two (2) 10/100 Base-TX copper RJ45 ports alongside two (2) 100Base-FX multimode fiber optic ports terminating in duplex SC connections
  • The multimode fiber architecture allows reliable, noise-insulated data propagation reaching standard functional limits of 4km to 5km
The Schneider Electric TCSESM043F2CU0 network TCP/IP switch is designed to enhance connectivity in network environments. This device supports four Ethernet ports, two supporting 100BASE-FX fiber connections and the other two supporting 10/100BASE-TX copper connections. The switch features a Transparent Ready (TRA) design, allowing for easy integration into existing infrastructure. It supports unlimited cascading, providing high flexibility for network design. Each port is equipped with network security features, particularly port hardening, effectively preventing unauthorized access and threats.

Regarding connection types, the switch supports full-duplex SC fiber and shielded RJ45 copper, and is compatible with CAT5E copper and multimode fiber. The maximum distance for copper connections is 100 meters. For fiber performance, the switch can handle transmission distances of up to 4 kilometers (62.5/125 microns) and 5 kilometers (50/125 microns).

The TCSESM043F2CU0 Schneider Electric ConneXium Managed Switch may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
