Siemens 6GK1105-2AA00 Programmable Logic Controller Module

Siemens 6GK1105-2AA00 is an optical switch module for SIMATIC NET OSM/ESM networks. It provides two fiber-optic ports (FO) at 100 Mbit/s and six electrical ITP ports at 10/100 Mbit/s, enabling mixed-media connectivity in industrial Ethernet architectures. The unit is powered from a 24 V DC supply with a redundant input and includes a signaling contact plus an integrated redundancy manager to support high-availability configurations. As part of the OSM/ESM family, it supports network management via Siemens Web-Based Management, accessible via standard browser interfaces for status monitoring and configuration. The 6GK1105-2AA00 order number identifies this OSM ITP62 Optical Switch Module variant with these port counts and performance characteristics, making it suitable for segmenting network paths and providing resilient connectivity in automation environments.
