The DIO021E is a remote I/O with 8 digital inputs, 2 digital outputs and 4 analog inputs, that is controlled via an Ethernet interface. All digital inputs can be used as PWM or event counter. The two digital outputs are isolated and allow bidirectional current flow. The analog inputs can be used for voltage (±10 V), current (±20 mA) or resistive measure-ments (10?…5k?). All I/O channels, digital and analog, are galvanically isolated from the internal logic and the Ethernet interface.
Additionally, the I/O module offers a serial interface (RS232/422/485), a maintenance port to access the command-line interface, an extension port for I2C, SPI and 1-Wire communication and 7 CODE inputs. The CODE inputs can be used to generate an index, which enables geo-graphical addressing by the application.
The integrated Ethernet controller, designed by duagon, features hardware prioritization and very low jitter. The Ethernet interface supports various real-time commu-nication stacks, e.g. EtherNet/IP – CIP, IPTCom or TRDP. The real-time protocols are built upon duagon's proprietary UDP stack, enabling process data prioritization to decrease the message latency.
Furthermore, the Ethernet interface is compliant to IEEE 802.3 and supports autonegotiation, auto MDI-X as well as half and full duplex.
The DIO021E offers a secure web front-end (HTTPS), that can be used for diagnostic purposes and to upload and execute firmware updates.
The applications running on the DIO021E are generally developed by the customer. duagon provides a build environment including the development library, which is 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 DIO021E 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
