The new 3U CompactPCI board F403 with 16 bidirectional digital I/O channels has been designed specifically for modern railway applications. It is suited for many different control functions, such as door-locking control and interior lighting. The board supports a total of 16 bidirectional digital I/O channels, organised into four optically isolated groups for reliable data transmission with four channels in each group.

In addition to accommodating configuration as either an input or output, each channel features an individual edge-triggered interrupt.

A voltage range of 14.4 VDC to 154 VDC with a current output of 1 A at 24 V complies with EN 50155, making the board ready for immediate use in train applications, as well as able to handle digital I/O signals with different voltage levels and ground references.

The four front connectors use spring cage terminal blocks facilitating low wiring outlay and enabling fast installation, while ensuring a secure connection.

Operating temperature is -40 to +85°C for qualified components. The board withstands a maximum of 95% relative humidity during operation and shock up to 50 m/s2. Functional vibration is 1 m/s2 and lifetime vibration is 7.9 m/s2, both from 5 Hz to 150 Hz.

The F403 is equipped with all safety measures necessary for mobile environments, including voltage and temperature supervision as well as readback of outputs to provide a reliable, robust solution for all controlling means in the rail market.
