Ruggedized 24-port switch for real-time Ethernet communication
The fail-silent switch architecture addresses IEC 61508 SIL 2, while the unique deterministic Ethernet features provide guaranteed timing properties of critical network traffic. The switch is intended for use in industrial applications with high availability and safety requirements.
This 24-port switch is part of a family of rugged and certified switches that support the deterministic Ethernet technology TTEthernet. TTEthernet enables hard real-time operation in distributed systems based on Ethernet networks. The technology provides full scalability for real-time architectures. Certifiable partitioning allows for changes in one application without the need for recertification of other applications.
Combined with the fail-safe properties of IEC 61508 certification guidelines, TTEthernet switches allow building network architectures where critical traffic is transmitted simultaneously over multiple network routes, providing transparent, lossless and immediate fail-over in case of network or switch failures. Fault-tolerant network routes with zero fail-over time can be created to meet even the strictest requirements for real-time communication availability and zero data loss. The switches contain a dedicated certifiable deterministic switching engine, but also an additional non-certifiable processor for adding layer-3 or customer-specific functions.
The rugged 24-port TTEthernet switch model offers 18 ports with 100 Mbit/s and 6 ports with 1 Gbit/s with SFP slots for flexible choice of the transmission medium in standard 19-inch rack format and with passive cooling. A variant with RJ45 connectors for low-cost standard cabling is also available. Customization is possible.
