Belden RS2-4TX 1FX Ethernet Switch

Belden Hirschmann RS2-4TX/1FX EEC Rail Switch is an unmanaged industrial Ethernet rail switch that combines four 10/100BASE-TX RJ-45 ports with a single 100BASE-FX fiber port (SC connector) on a DIN-rail module. It delivers store-and-forward switching at up to 100 Mbps per copper port and supports auto-negotiation, auto-crossing (MDI/MDIX), and auto-polarity on copper links. The 100BASE-FX uplink commonly uses multimode fiber with an SC connector in the standard EEC configuration, enabling robust extensions of Ethernet segments over fiber in harsh industrial environments. Designed for rugged use in automation, the RS2-4TX/1FX EEC includes link-loss and power-loss alarms and four fault-relay outputs to signal faults remotely, with an operating temperature range from -40°C to +70°C and DIN-rail mounting for compact cabinet integration. This combination of copper and fiber connectivity makes it suitable for bridging Ethernet networks in manufacturing, process control, and packaging lines where a quick, unmanaged upgrade is needed.
