Industrial Ethernet Communication Characteristics

The TCSESU053FN0 operates as an unmanaged Layer 2 Ethernet switch with five 10BASE-T/100BASE-TX copper interfaces. Each port uses shielded RJ45 connectivity and supports CAT 5E twisted shielded pair cable. Auto MDI/MDX removes the requirement to select straight-through or crossover cabling manually.

The switch performs automatic 10/100 Mbps negotiation and duplex-mode negotiation. Received Ethernet frames are stored and re-routed through the appropriate port. Automatic polarity correction supports the physical-layer connection without manual polarity adjustment.

Frequently Asked Questions

Q: What supply voltage does the TCSESU053FN0 require?
A: The rated supply range is 12-24 VDC, with allowable supply limits of 9.6-32 VDC SELV. Power consumption is specified as 2.2 W.

Q: What Ethernet cable and distance are supported?
A: The switch uses CAT 5E twisted shielded pair copper cable through shielded RJ45 connections. The specified maximum distance between devices is 100 m.

Q: Can the TCSESU053FN0 be installed on a DIN rail?
A: Yes. The unit is designed for mounting on a 35 mm symmetrical DIN rail. Its enclosure is rated IP30.

Field Installation Guidelines

• Mount the switch on a 35 mm symmetrical DIN rail with adequate mechanical clearance around the enclosure.
• Connect the 24 VDC-class supply through the supplied 3-way removable power connector while observing DC polarity and the specified voltage limits.
• Use shielded CAT 5E twisted-pair copper cable for the Ethernet connections.
• Keep Ethernet cabling separated from high-voltage power conductors and high-current switching circuits where practical to reduce electromagnetic coupling.
• Terminate cable shields according to the cabinet grounding and EMC design of the installation.
• Verify the power LED before commissioning Ethernet links.
• Check the per-port link-status and data-rate LEDs after cable connection to confirm physical-layer activity.
• Maintain the specified 0-60 deg C operating environment and 0-95% non-condensing relative humidity range.
• The product is IP30; installation should therefore provide protection against dust, water ingress, and mechanical exposure beyond the enclosure rating.
• TCSESU053FN0 was discontinued on March 15, 2022. The supplied Schneider Electric documentation identifies MCSESU053FN0 as the replacement model.
