Ethernet Physical Layer and Switching Characteristics

The TCSESU083FN0 provides eight copper Ethernet ports supporting 10BASE-T and 100BASE-TX communication. Each port uses a shielded RJ45 connection and is specified for shielded CAT 5E twisted-pair cabling.

The unit is an unmanaged Ethernet TCP/IP switch, so the supplied data path is based on transparent Ethernet switching rather than configurable network management functions. The specified maximum copper segment length is 100 m between connected devices.

Local LEDs provide separate indications for the power supply and each Ethernet channel. Each channel has a yellow LED for ETH LINK/data rate indication and a green LED for connection status.

The switch accepts 9.6-32 VDC SELV within its specified supply limits and has a rated power consumption of 4.1 W. Its 35 mm DIN-rail mounting format is suitable for control cabinet installation.

A: The nominal operating voltage is 12-24 V, with a specified supply range of 9.6-32 VDC SELV and a power consumption of 4.1 W.

Field Installation Guidelines

Mount the TCSESU083FN0 on a 35 mm symmetrical DIN rail and provide wiring clearance around the 35 mm wide enclosure. Connect the removable three-pin power connector using a DC supply within the specified 9.6-32 VDC SELV range.

Use shielded CAT 5E twisted-pair Ethernet cable with the integrated shielded RJ45 interfaces. Keep individual copper Ethernet segments within the specified 100 m maximum. Route Ethernet cabling separately from high-voltage or high-current conductors where practical to reduce electromagnetic coupling.

Terminate and bond cable shields according to the cabinet grounding design and applicable installation standards. Verify supply polarity, connector seating, and link status LEDs before commissioning. The IP30 enclosure is intended for protected control-cabinet installation rather than direct exposure to water or dust.

The TCSESU083FN0 was discontinued on 21 January 2022. The supplied Schneider Electric data identifies MCSESU083FN0 as the recommended replacement.
