DXIO0808M – MVB DIGITAL REMOTE I/O MODULE

The DXIO0808M is a remote I/O with 8 digital inputs and 8 combined input/outputs that is controlled via an MVB interface. The combined inputs and outputs are software configured and may be used as I/O read-back. All I/O channels can be configured as PWM (output) or frequency or event counter (input). They are galvanically isolated from the internal logic and the MVB interface. Additionally, the I/O module offers 6 CODE inputs, used to generate an index, which enables geographical addressing by the application. The DXIO0808M provides one line redundant galvanically isolated interface with lines A and B. EMD or ESD+ can be chosen as physical layers. duagon's MVB controller is implemented in an FPGA and supports all 4096 process data ports. An additional 32-bit soft processor handles the complete message data stack with an easy-to-use interface. The optional bus administrator manages the complete MVB network and can be configured using duagon's proprietary network tool. The application running on the DXIO0808M is generally developed by the customer. duagon provides a build environment including the development library required to implement any customer-specific application. The development library is accompanied by a simple demo application. On request duagon offers the application development as an engineering service. Please contact duagon for more information about the possibilities. The DXIO0808M can be powered directly from battery, supporting voltage ranges of 24 Vdc to 110 Vdc. It is designed for harsh rolling stock environment and complies with the EN 50155 standard by:

• -40 to +70°C operating temperature
• coating against humidity
• enhanced EMI and vibration robustness
