New switch for seamless network redundancy in critical applications
With the FL Switch 4300-4GSFP-RED, Phoenix Contact is expanding its portfolio for high-availability industrial networks. As a high-performance Layer 2 managed switch, it enables latency-free 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, allowing for flexible integration into industrial networks. Thanks to its various power supply options, the device can be flexibly adapted to different industrial environments.
Additional benefits include support for IEEE 1588v2 One-Step Transparent Clock for precise time synchronisation, redundant power supplies for higher network availability, and Single-RedBox redundancy.
With an operating temperature range of -40 degC to +85 degC and a rugged IP20-rated enclosure, the switch is suitable for demanding industrial applications.
