The D521 is a WTB to MVB Gateway compliant to IEC 61375 and UIC Leaflet 556. The gateway is built with two WTB medium attachment units. Line A and B interfaces are galvanically isolated, enabling cable redundancy, and use standard 9-pole SUB-D type connectors. To overcome contact oxidation, the WTB gateway has an optional built-in fritting mechanism. The integrated WTB controller, realized on FPGA with duagon IP, can be configured to act as a strong or weak master or as a slave.
The gateway is delivered with a build-in UIC 556 conform mapping server application, handling message data communication and process data marshalling between the WTB and the MVB consist network. Safe data transmission can optionally be ordered. A complete configuration and integration toolchain is provided, including a configuration tool, to easily configure the application and allowing the gateway to be seamlessly integrated into any network architecture.
duagon's own MVB controller is implemented on FPGA and supports the full 4096 process data ports. The train consist network interface complies with the TCN standard IEC 61375 up to class 4.
The D521 offers 8 digital inputs and 8 combined input/output channels. The I/O channels are used by the application to implement battery voltage monitoring, redundancy switch over and a "wake-up" signal.
The WTB gateway is connected directly to the train battery and supports all voltage types from 24 to 110 Vdc. Moreover, it has a built-in power save mode. The service interfaces accessible via Ethernet offers quick access to diagnostic information and all recorded data.
The D521 is designed for harsh rolling stock environments and is fully compliant with EN 50155.
