Description
The Siemens 6GK5208-0BA10-2AA3 SCALANCE X208 is a managed layer 2 industrial Ethernet switch designed for configuring linear, star, and ring network topologies. It provides reliable data communication across plant floors and control networks in industrial automation environments.
Main Features
This switch includes 8 RJ45 ports operating at 10/100 Mbit/s with auto-negotiation and auto-crossover functionality. It incorporates an integrated redundancy manager to support high-speed ring redundancy, preventing network downtime. Configuration and network monitoring are available through Web-Based Management (WBM), SNMP, and integrated PROFINET diagnostics.
Benefits
Redundant 24V DC power supply connections alongside signaling contact outputs enhance operational reliability by alerting operators to power or link failures. The rugged IP30 metal housing and DIN-rail or wall-mounting options allow installation in tough control cabinet environments.
Applications
The SCALANCE X208 is used across factory automation, process plants, infrastructure projects, and machine building. It connects controllers, human-machine interfaces (HMIs), distributed I/O racks, and IP cameras within secure industrial networks.
