F305 - Quad Fast Ethernet & Real-Time Ethernet Interface Board
Fast Ethernet for Railway Applications
The F305 is a 3U CompactPCI 100-Mbit/s networking controller with a strong focus on railway applications. It comes in a compact 4 HP, one-slot width even with its rugged M12 connectors.
The card provides four Fast Ethernet channels, supporting full-duplex or half-duplex with 10BASE-T and 100BASE-TX physical layers for distances up to 100 m.
As an assembly option, the board is available with or without a real-time Ethernet controller and extended connectivity, making it scalable to system requirements.
Real-Time Ethernet for d-SC
The F305 has a special function as the real-time Ethernet component inside the controller of the duagon SAFE CONTROL System. d-SC is a platform to perform safe control functions, for example in rolling stock applications like Automated Train Operation (ATO) or Automated Train Protection (ATP). It usually consists of the MH50C d-SC controller system and safe remote I/O boxes.
Ring Topology
The distributed d-SC subsystems are connected via RT Ethernet in a ring, tolerating single failures.
For example, in case of a broken cable, the entire system is still fully operational, as all d-SC subsystems can still be reached from the other end of the ring.
The F305 offers the capability of short-connecting two front channels via software.
Access to System-Internal d-SC I/O Cards
In d-SC systems the F305 has a direct link to I/O cards on the same backplane, using the d-SC EBUS, power supply, and address lines. As the F305 itself has no special safety mechanisms and certification, the board must be considered as a black channel.
EN 50155 Rolling Stock and EN 50121-4 / EN 50125-3 Wayside Compliance
The F305 was fully designed to meet the requirements both for vehicle and wayside applications. Its operating temperature complies with the class TX specifications of -40 °C to +70 °C (10 minutes up to +85 °C). Standard boards include conformal coating.
Along with its railway standard compliance and long-term availability of a minimum 10 years, the F305 is a rail-ready component, saving time to market and costs.
