Siemens 6GK1105-2AE00 SIMATIC NET Optical Switch Module OSM TP22

The Siemens SIMATIC NET OSM TP22 (6GK1105-2AE00) is a robust industrial switch module designed to provide secure, high-availability connectivity within demanding Ethernet-based automation networks. By integrating advanced redundancy management, this module ensures reliable, deterministic data exchange, making it a critical component for backbone network infrastructure in environments prone to electromagnetic interference.

Features

• Redundancy Management: Built-in hardware-based Redundancy Manager (RM) for rapid, sub-millisecond ring reconfiguration during segment failures.
• Fiber Optic Backbone: Two 100 Mbit/s fiber optic ports providing complete galvanic isolation and immunity to EMI.
• Copper Connectivity: Two 10/100 Mbit/s RJ45 ports for efficient integration of local controllers, HMIs, and field devices.
• Diagnostic Capabilities: Includes four digital inputs for status monitoring and a dedicated signaling contact for hardware-level alarm triggering.
• Redundant Power: Dual 24 VDC power supply inputs with automatic failover to ensure continuous operation during power rail instability.

Applications

This module is widely utilized in sectors requiring high network uptime and structural resilience, including petrochemical processing, power distribution substations, and large-scale manufacturing facilities. It serves as a primary node for managing complex ring topologies where data loss cannot be tolerated.

Technical Specifications

Installation Guidelines

• Ensure the module is mounted in a location with adequate airflow to maintain operating temperatures within the 0 to 60 deg C range.
• Use redundant power sources connected to the dual terminal blocks to maximize uptime.
• Verify that fiber optic connections are clean and properly seated to prevent signal attenuation.
• Ensure the module chassis is properly grounded in accordance with local industrial electrical standards to mitigate noise.
• Always disconnect power before installing or removing the module from the DIN-rail or rack system.

FAQ

Does this module support dual power supplies? Yes, the 6GK1105-2AE00 features a redundant 24 VDC power input design that automatically switches to the secondary supply if the primary fails.

What type of redundancy does this switch provide? It functions as a Redundancy Manager, allowing it to control and monitor ring topologies to prevent network downtime in the event of a cable break or node failure.
