Phoenix Contact FL Switch 1108 REG Industrial Ethernet Switch, 8-Port 10/100 Mbps, DIN Rail, Redundant Power 1473643

In industrial automation, network downtime caused by a single power supply failure or an unmanaged switch that cannot handle harsh environments leads to costly production stops. The Phoenix Contact FL Switch 1108 REG addresses this by providing eight Fast Ethernet ports in a rugged DIN-rail mountable housing with redundant power inputs, ensuring reliable connectivity for machines and control systems.

Who is it for

This switch is built for control engineers, system integrators, and maintenance teams who need a simple, unmanaged Ethernet switch that can be installed directly on a DIN rail inside a control cabinet. It suits small to medium industrial networks where deterministic data exchange and high availability are required without complex configuration.

Main features

• Eight RJ45 ports supporting 10/100 Mbps Fast Ethernet for connecting PLCs, HMIs, IP cameras, and other industrial devices.
• Redundant power supply input (12 V DC to 48 V DC) allows connection to two independent power sources, so the switch continues operating if one fails.
• DIN rail mounting for quick installation in standard industrial enclosures.
• Unmanaged operation – no configuration needed, plug and play.
• Robust aluminum housing with IP20 protection, suitable for control cabinet use.
• LED indicators for power, link status, and data activity for easy diagnostics.
• Wide operating temperature range from -10 °C to 60 °C.

Tips

To maximize uptime, connect the two power inputs to separate power supplies or different phases. Ensure proper ventilation inside the cabinet, as the switch is designed for operation up to 60 °C. Use shielded Ethernet cables in noisy industrial environments to maintain signal integrity.
