SCALANCE X204-2 managed Industrial Ethernet switch

X204-2 6GK5204-2BB10-2AA3

Spare Part Number

PNSCALANCE X204-2 managed Industrial Ethernet switch

Product Information:

The Siemens X204-2 6GK5204-2BB10-2AA3 is a managed SCALANCE Industrial Ethernet switch with four 10/100 Mbit/s RJ45 copper ports and two 100 Mbit/s multimode BFOC fiber-optic ports. It is designed for deterministic, diagnosable network structures in industrial automation systems.

The switch functions as a PROFINET IO device and includes network management, LED diagnostics, a signaling contact with set button, an integrated redundancy manager, redundant 24 V DC power inputs, and optional C-PLUG configuration memory. Siemens documents 100Base-FX fiber operation, 6.36 W power loss, and an operating range from -40 to 60 °C.

Siemens cancelled 6GK5204-2BB10-2AA3 in October 2024 and identifies SCALANCE XC206-2 or XC206-2SFP as successor options. Replacement requires checking fiber connector and media type, port count, ring-redundancy settings, PROFINET device configuration, IP address, VLAN and management parameters, mounting, and power terminals.
