The new 3U CompactPCI Serial board G403 with 16 bidirectional digital I/O channels has been designed specifically for modern railway applications. The new board is suited for many different control functions, such as door-locking control and interior lighting.

The new G403 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 an 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.

The G403 is equipped with all safety measures necessary for mobile environments, like voltage and temperature supervision as well as readback of outputs and conformal coating against dust and humidity. This makes the G403 a reliable, robust solution for all controlling means in the rail market.
