SR429/4M
FEATURES
  • The ARINC 429 MULTI-BIT CONVERTER from Applied Avionics can convert up to four different bits from a single ARINC 429 data label to discrete outputs
  • Polarity of the four outputs is selectable by bit
  • ARINC 429 MULTI-BIT CONVERTER is an 8-pin device, expandable to a 12-pin
  • The ARINC converter circuitry inside the ARINC 429 MULTI-BIT CONVERTER includes an internal Health Monitor that can provide a “fail” indication if power to the decoder is lost or upon loss of valid ARINC data input
  • The Health Monitor has a range of watchdog timings requiring a valid ARINC label to be received within a specified time interval
  • Health Monitor signal can be selected as one of the discrete outputs
  • This device is part of our NEXSYS Component Technology and is configurable inside of a VIVISUN switch/annunciator or a NEXSYS Module
  • When used in a VIVISUN switch/annunciator, the compact size of the converter allows for the inclusion of additional NEXSYS components or electro-mechanical switch poles
  • The ARINC 429 MULTI-BIT CONVERTER is designed, tested and qualified to applicable military standards
  • Meets the environmental requirements of DO-160
  • ARINC 429 MULTI-BIT CONVERTER is an 8-pin device that converts up to four ARINC 429 data bits to discrete outputs
  • The polarity of each output (Open when Bit = 1 or Ground when Bit = 1) can be selected by bit
  • Internal Health Monitor can also be a selected output, with polarity option (Normal = Ground, Fail = Open or Normal = Open, Fail = Ground)
  • By increasing to a 12-pin package, the standard and inverted polarities of the four selected bits can be available
  • Also in an expanded 12-pin package, the four discrete bits can be supplemented with a 2 X 4 decode of the two SSM bits (Bits 30 and 31) with polarity options
  • Additionally, the internal Health Monitor can be used in place of the SSM decode “00

In relation to NE (New) parts, many OEMs change their prices and availability without any notice to dealers or the industry. Therefore, through the REQUEST or RFQ indication, we ask that customers contact us for the most accurate price and availability.

In relation to SV & OH parts, the used parts aftermarket in the aviation industry is not an infinite supply. It is a dynamic, constantly changing market that is significantly affected by and susceptible to highs and lows in supply and demand. Therefore, although we attempt to, at times, we are unable to predict the exact moment when an item may be available. Once again, through the REQUEST or RFQ indication on our website, we ask that customers contact us for the most current and accurate price and availability.
