What Happens When Your Control Network Needs More Ports?
Adding devices to a control cabinet often creates a cabling bottleneck. The TCSESU083FN0 from Schneider Electric solves this with eight shielded RJ45 ports in a compact DIN-rail package. This ConneXium unmanaged switch delivers plug-and-play Ethernet connectivity without configuration software. The TCSESU083FN0 is an active, in-production model in the ConneXium range, so you can specify it for new builds and replacements with confidence.

Key Specifications That Drive Performance
Eight Shielded Copper Ports
The switch provides 8 x shielded RJ45 10/100BASE-TX copper ports. Shielded connectors reduce electromagnetic interference in cabinets crowded with drives and contactors. You connect PLCs, HMIs, and remote I/O without extra media converters.
1.6 Gbps Switching Capacity
A 1.6 Gbps switching capacity handles simultaneous traffic across all ports. The 8K-entry MAC table stores addresses for stable forwarding. Jumbo frames up to 9216 bytes pass through, which suits large data transfers between controllers and servers.
Wide DC Supply Range
The unit accepts 9.6-32V DC (SELV) and consumes only 4.1 W. This range covers common 12 V and 24 V control supplies. Low power draw keeps cabinet heat minimal.
Compact DIN-Rail Housing
Dimensions of 35 x 138 x 121 mm and a weight of 0.246 kg save panel space. The 35 mm symmetrical DIN rail mounting matches standard enclosures. An IP20 rating suits protected cabinet environments.
Where This Switch Fits in Industrial Networks
Machine-Level Connectivity
Machine builders add the TCSESU083FN0 when a panel needs more Ethernet drops. The unmanaged design removes configuration time from the build schedule.
Control Cabinet Expansion
When a line adds a second HMI or vision camera, spare ports are scarce. This switch provides eight ports with transparent Ethernet TCP/IP forwarding. The Transparent Ready concept supports simple integration into existing architectures.
Replacement and Upgrade Projects
Legacy unmanaged switches often fail from aging power supplies. This active ConneXium model gives maintenance teams a like-for-like replacement path. Unlimited cascade capability means you can daisy-chain switches as the network grows.

Installation and Setup Guidance
Mount the switch on a 35 mm symmetrical DIN rail inside a protected enclosure. Connect the 9.6-32V DC (SELV) supply according to local electrical codes. Use shielded RJ45 cables to maintain signal integrity. Because the switch is unmanaged, no IP address or software setup is required. Verify link LEDs after power-up. Keep cable runs within Ethernet distance limits for reliable 10/100BASE-TX operation.
Maintenance and Long-Term Reliability
The TCSESU083FN0 has no fans or moving parts, so wear points are minimal. Inspect the unit periodically for loose connections and dust buildup. Confirm the cabinet stays within the IP20 protection environment. Check that supply voltage remains within the 9.6-32V DC (SELV) range. A stable supply protects the internal electronics and extends service life. SpareTechPLC stocks this model for quick replacement when unplanned downtime occurs.
Compatibility and Integration Notes
This switch supports Ethernet TCP/IP and works with PLCs, HMIs, drives, and I/O modules that use standard Ethernet. The Transparent Ready concept aligns with Schneider automation architectures. Unlimited cascade lets you expand port count by linking multiple switches. The 8K MAC table and 9216-byte jumbo frame support handle mixed traffic from control and supervisory systems.
What to Verify Before You Buy
Confirm your panel has a 35 mm symmetrical DIN rail and a 9.6-32V DC (SELV) source. Check that eight RJ45 ports match your device count. Verify the IP20 rating suits your enclosure. If you need managed features such as VLANs or SNMP, this unmanaged model will not provide them. Contact SpareTechPLC to confirm current availability and lead time before ordering.
