Siemens 6GK1105-2AA10 Simatic Interface Module

Siemens 6GK1105-2AA10 is a SIMATIC NET OSM ITP62 Optical Switch Module, pairing two fiber-optic (FOC) ports with six 10/100 Mbit/s electrical ports to route traffic between fiber and copper network segments. It includes eight digital inputs, a signaling contact, and a redundant 24 V DC power supply, plus an integrated Redundancy Manager with network management to sustain operation during link or power faults. The optical interfaces use BFOC multimode sockets for fiber links up to 3 km, while copper interfaces support 10/100 Mbit/s transfer rates. As part of the SIMATIC NET OSM/ESM family, the 6GK1105-2AA10 is designed for deployments requiring optical switching between network segments with integrated redundancy and network management.
