Siemens 6GK1105-2AA10 Industrial Ethernet Module

Siemens 6GK1105-2AA10 is a SIMATIC NET Industrial Ethernet OSM ITP62 optical switch module that provides two fiber-optic ports (FO) at 100 Mbit/s plus six 10/100 Mbit/s ITP ports and eight digital inputs for field-level signaling. The unit is powered from a redundant 24 V DC supply and includes a signal contact, while an integrated redundancy manager with network management supports high-availability operation and streamlined topology control within a SIMATIC NET environment. Rated for industrial use, it supports ambient temperatures up to +55°C, making it suitable for demanding plant installations. The 6GK1105-2AA10 is documented as a discontinued model with lifecycle end date August 1, 2023, according to Siemens and distributor listings. This optical switch module is designed to extend fiber-optic backbones and manage Ethernet topology in environments where reliability and redundancy are critical, aligning with the OSM/ESM family of devices in the SIMATIC NET portfolio.
