ARINC 429 to +/-10V DC
This ARINC 429 to +/-10Vdc Output converter is in use by many companies who have a requirement to extract a specific ARINC 429 parameter from a user selectable Label and translate it into a +/-10VDC output.
The Octal Label, the SDI, SSM are all selected via setting DIP switches on the PCB. The ARINC 429 to 0-10Vdc output 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 +/-10Vdc Output converter is powered from an external 28 VDC (18-72V) nominal supply with an internal current and thermal (150 ºC) fuse. The power inputs are reverse polarity protected.
FPGA ONLY architechture - No microprocessor - RTCA DO-278 not required.

All units are designed to meet UK, European, US EMC regulations and RTCA DO-160G.
ARINC 429 to +/-10V DC Detail
Three LED indicators (optional) are provided and these indicate the following status:
- LED indicating received data
- LED indicating Low Speed data
- LED indicating High Speed data
The ARINC 429 to +/-10Vdc Output converter uses a 12-Bit D/A resolution 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:
