Siemens 6GK1105-3AB10 Industrial Ethernet Switch

Siemens 6GK1105-3AB10 is an ESM TP80 Electrical Switch Module in the SIMATIC NET family, delivering eight RJ45 ports for 10/100 Mbps Ethernet plus eight digital inputs in a single, compact module. Designed for industrial control cabinets and small-to-midsize networks, it combines switching with input sensing capabilities to streamline wiring and monitoring at the edge. The unit is powered by a redundant 24 V DC supply and includes an integrated redundancy manager to sustain network connectivity during power faults, supporting high-availability operation in harsh environments. With built-in network management, it can be integrated into industrial Ethernet topologies and coordinated with other SIMATIC NET devices, aiding diagnostics and centralized configuration. Typical applications include interconnecting sensors, actuators, PLCs, and I/O blocks within a cabinet or across a lean automation network, where reliable port density, straightforward wiring, and redundancy are prioritized for continuous production uptime.
