Siemens 6GK1105-3AB10 Profibus Interface Module

Siemens 6GK1105-3AB10 ESM TP80 Electrical Switch Module is a compact eight-port industrial Ethernet switch designed for Siemens PROFIBUS/Industrial Ethernet networks. It supplies eight RJ45 ports supporting 10/100 Mbps Ethernet for straightforward device-to-device interconnection and small-star topologies on the factory floor. The unit is DIN-rail mountable and powered from a 24 V DC supply with a redundant voltage input to improve reliability in demanding environments. A signaling contact and an integrated redundancy manager support failover and network availability, while the signaling interface and power connections are implemented on a 6‑pole terminal block. The module architecture provides eight electrical connections for network components and terminal equipment, plus one signaling contact and one redundant power path, making it suitable for compact automation cabinets where space, reliability, and straightforward local networking matter.
