TCSESM043F2CS0 Managed Switch | Schneider 2-Port Fiber

What Is the TCSESM043F2CS0?

The TCSESM043F2CS0 is a Schneider Electric ConneXium managed Ethernet switch. Specifically, it is a Layer 2 device with two RJ45 copper ports and two single-mode fiber ports. Therefore, it suits deterministic industrial networks that require both local copper connections and long-distance fiber links. In addition, the switch supports the Transparent Ready concept for transparent data exchange.

TCSESM043F2CS0 Key Features and Technical Specs

• Managed Layer 2 switch: Provides full control over network traffic and diagnostics.
• Port configuration: 2 x RJ45 10/100BASE-TX copper plus 2 x 100BASE-FX single-mode fiber (SC duplex).
• Supply voltage: 24V DC nominal, with a 9.6–32V DC range for flexible power sources.
• Switching capacity: 5.6 Gbps ensures non-blocking throughput.
• MAC table size: 8K entries support medium to large networks.
• Jumbo frame support: 9216 bytes for efficient large-packet transmission.
• Redundancy: HiPER ring and RSTP, with up to 50 ring nodes.
• Protocol support: Ethernet TCP/IP, SSH, HTTP, HTTPS, SNMP, RS232, LLDP, Telnet, SNTP, and MRP.
• Cybersecurity: Port hardening restricts unauthorized access.
• Mounting: 35 mm symmetrical DIN rail for control cabinet installation.
• Protection rating: IP20 for use in clean, protected environments.
• Dimensions (H×W×D): 47 × 131 × 111 mm.

Notably, the combination of single-mode fiber and managed redundancy makes this switch ideal for ring topologies that span long distances. Furthermore, the 5.6 Gbps switching capacity and 8K MAC table provide headroom for future expansion. Operating temperature is not available in the provided data; refer to the official datasheet for that specification.

Applications and Use Cases for the TCSESM043F2CS0

Industrial networks often require a mix of copper and fiber connectivity. Consequently, the TCSESM043F2CS0 fits applications such as factory automation, process control, and infrastructure monitoring. For example, in a manufacturing plant, the copper ports can connect local PLCs and HMIs, while the fiber ports link distant control rooms. Additionally, the HiPER ring redundancy ensures network recovery if a cable breaks, which minimizes downtime. Because the switch supports MRP, it integrates into redundant ring architectures. Therefore, it is a precise choice for engineers who need verified reliability in harsh environments.

Integration and Compatibility

The TCSESM043F2CS0 integrates with Ethernet TCP/IP networks and supports SNMP for management. It also works with SCADA and DCS systems that use standard Ethernet protocols. When deploying fiber, use SC duplex connectors and single-mode cable. For ring topologies, configure HiPER ring or RSTP according to the manual. Because the switch is managed, you can monitor traffic and set up VLANs. However, note that the RS232 port is available for console access. Integration Note: wiring into managed networks may require an external gateway or connection module; confirm cables and gateways with the supplier.
