Siemens 6GK5208-0BA00-2AC2 SCALANCE XC208 8-Port Managed Layer 2 Industrial Ethernet Switch

The Siemens 6GK5208-0BA00-2AC2 SCALANCE XC208 is a managed Layer 2 Industrial Ethernet switch with 8x 10/100 Mbit/s RJ45 ports, a console port, and redundant 24 V DC power inputs, rated IP20 for -40 to +70 °C operation. It supports PROFINET IO device conformity class B, RSTP/MRP ring redundancy, and IEC 62443-4-2 cybersecurity certification, with mounting on DIN rail, S7-300/S7-1500 rail, or wall.

Selection Notes

The fixed 8-port RJ45 configuration and dual power inputs make the XC208 a fit for machine-level segments that need up to 8 Ethernet drops with power redundancy, not for larger cell-level backbones. PROFINET conformity class B plus MRP and HRP ring-redundancy support let it sit in a ring topology with sub-300 ms reconfiguration, and the -40 to +70 °C rating and IEC 62443-4-2 certification suit unheated cabinets in security-conscious plants. Where more than 8 ports or fiber uplinks are needed, a larger-port-count or SC-port SCALANCE variant is the better fit.

Applications

PROFINET machine networks needing redundant ring topology (MRP/HRP), unheated or outdoor cabinets down to -40 °C, and DIN-rail or S7-1500 rail integration alongside SIMATIC controllers.
