MEN Micro Inc. (Blue Bell, PA) has released the F403, a 3U CompactPCI board with 16 bi-directional digital I/O channels. 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 F403 supports a total of 16 bidirectional digital I/O channels, organized 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. 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 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. 

Technical specifications:

  • 16 bidirectional binary I/Os.
  • Reduced wiring through spring cage terminal blocks.
  • I/O voltage range 14.4 VDC to 154 VDC, current output 1 A at 24 V.
  • Driver support for all common operating systems.
  • -40° to +85° C with qualified components.
  • Conformal coating against dust and humidity.
  • EN 50155 compliant.
