The Advantech EKI-7712E-4FI-BE is a managed industrial Ethernet switch for traffic controllers, roadside cabinets and other outdoor enclosures. It has 8 copper 10/100 ports and 4 Gigabit SFP slots, runs from -40 to +75 °C, and is rated to NEMA TS2 for traffic control and EN 50121-4 for railway trackside use.
In a traffic controller, the SFP ports carry fibre between junctions, and the copper ports connect the controller itself, CCTV cameras and the sensors at that junction. X-Ring Pro restores a broken fibre ring in under 20 ms, with STP, RSTP and MSTP as standard alternatives. Dual 12–48 V DC inputs give power redundancy, and the relay output can signal a fault to the cabinet. Security is certified to IEC 62443-4-2 SL2, with 802.1X and RADIUS.
SFP modules are chosen separately to suit the fibre type and distance. Where the cabinet also needs a cellular link, it pairs with the Advantech ICR-2834 or SmartStart routers.
