New Switch for Seamless Network Redundancy in Critical Applications
New high-performance layer 2 managed switch enables zero-latency redundancy via HSR (High-availability Seamless Redundancy) and PRP (Parallel Redundancy Protocol).
With the FL Switch 4300-4GSFP-RED, Phoenix Contact is extending its portfolio for high-availability industrial networks. As a high-performance layer 2 managed switch, it enables zero-latency redundancy via HSR (High-availability Seamless Redundancy) and PRP (Parallel Redundancy Protocol). This ensures uninterrupted network communication in applications where continuous operation is critical.
The switch combines powerful redundancy features with a comprehensive set of layer 2 functions, enabling flexible integration into industrial networks. With its various power supply options, the device can be adapted flexibly to different industrial environments.
Other benefits include support for IEEE 1588v2 One-Step Transparent Clock for precise time synchronization, redundant power supplies for higher network availability, and single RedBox redundancy. With an operating temperature range of -40°C to +85°C and a robust housing with an IP20 degree of protection, the switch is suitable for demanding industrial applications.
