ARINC 429 to 0 to +/-10V DC

This converter can decode a 2's compliment 13-bit word from an ARINC 429 Label and translate it into a 0 to +/-10V DC output.

The Octal Label, the SDI, SSM are all selected via setting DIP switches on the PCB. The converter adapts automatically to high or low speed (12.5/100kHz) ARINC 429 data and the inputs are opto-coupled for electrical isolation purposes. The ARINC 429 to +/-10V DC converter is powered from an external 28 VDC (18-72V) nominal supply with an internal current and thermal (102 ºC) fuse. The power inputs are reverse polarity protected.



FPGA ONLY architechure - No microprocessor - RTCA DO-178B not required.
All units are designed to meet the European, US EMC regulations and RTCA DO-160G.

ARINC 429 to 0 to +/-10V DC Detail

Three LED indicators are provided and these indicate the following status:
 

  • LED indicating received data
  • LED indicating Low Speed data
  • LED indicating High Speed data


The converter employs a 12-Bit D/A resolution IC that takes its input from an ARINC 429 word - bits 29..18.

Different output voltage options and resolutions are available upon request. 

 

The connections for the YED/429/R1/DAT1 Adapter are via two D15 D-type connectors:
