ARINC 429 TO ANALOG CONVERTER

ARINC429 to 0-10VDC ARINC 429 to Analog Output Data Translator Protocol Converter is also 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 0-10VDC output.

The Octal Label, the SDI, SSM and state of the parity (ODD/EVEN/NONE) 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 unit is powered from an external 28 VDC (18-36V) nominal supply with an internal current and 
thermal (102 Deg C) fuse. 
The power inputs are reverse polarity protected.

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

• LED indicating no received data
• LED indicating Low Speed data
• LED indicating High Speed data

The converter uses a 12-Bit D/A resolution converter that takes its input from an ARINC 429 word - bits 29..18. Different output voltage options and resolutions are available upon request. 
There is also a DIP switch option on the board which can be configured to allow data to be extracted from bits 26..15 of the ARINC 429 word.
