Siemens 6GK5108-0BA00-2AA3 Profibus DP Interface Module

Siemens 6GK5108-0BA00-2AA3 is a SCALANCE X108 unmanaged IE switch designed for industrial Ethernet networks, providing eight 10/100 Mbps RJ45 ports to interconnect PLCs, operator interfaces, sensors, and other automation devices in harsh factory environments. This non‑PoE variant (0BA00-2AA3) combines eight RJ45 network ports with a signaling‑contact terminal block and dedicated primary and redundant power inputs, delivering a compact, rugged solution for simple network expansion and reliable operation in control cabinets. As an unmanaged switch, it requires no configuration to forward frames between network segments, making it ideal for straightforward daisy‑chain or star topologies in industrial plants where automatic traffic handling and robust physical design matter more than advanced features. The device’s eight 10/100 Mbps ports use RJ45 connectors with securing collars for vibration resistance, and it is part of Siemens’ SCALANCE X108 family, a line of rugged, entry‑level Ethernet switches intended to integrate with other industrial networking equipment.
