DXIO0808C - CAN Digital IO Module

The DXIO0808C is a remote I/O with 8 digital inputs and 8 combined input/outputs that is controlled via a CAN 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 CAN interface.

Additionally, the I/O module offers 6 CODE inputs, used to generate an index, which enables geographical addressing by the application.

The DXIO0808C supports various protocols including CANpie, CANopen and J1939.

The application running on the DXIO0808C 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 DXIO0808C 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
