Product Overview

6GK5208-0BA00-2AA3 is a managed SCALANCE X208 Industrial Ethernet switch with eight RJ45 copper ports. It provides network management, diagnostics and redundant power connection for industrial Ethernet installations.

The switch can operate as a PROFINET IO device and in a redundant ring; an optional C-PLUG supports transfer of configuration data.

Ordering focus: Match the eight-port 10/100 Mbit/s X208 variant and check the network topology, power wiring and optional C-PLUG requirement.

Key Functions

Eight-port switching

Eight RJ45 jacks connect 10/100 Mbit/s twisted-pair network segments.

Fault monitoring

LED diagnostics and a signaling contact report switch and network conditions.

Redundant infrastructure

Two power inputs and support for redundant ring operation help integrate the switch into managed networks.
