SR429/1M
FEATURES
  • The SR429/1M is a single bit ARINC converter, with additional inputs for up to two independent discrete analog signals
  • The typical application for the SR429/1M is for failure indications, although the device can be used for a wide range of ARINC digital to analog conversion situations
  • What makes the SR429/1M device unique is its ability to be packaged inside a traditional switch, indicator or NEXSYS Module
  • Output will be normally Ground and become Open (high impedance) upon 1) a “fail” signal from the internal health monitor or 2) an indication from either of the optional external inputs
  • The internal fail sense circuitry simultaneously monitors the operation of the internal ARINC decoder and 2 optional external inputs and drives a single discrete output
  •  Applications include discrete single-bit warning, including ADS-B Out failures
  • Simple device, not subject DO-178 or DO-254 requirements
  • Can be specified for any single-bit on any single label
  • Other options include ARINC transmission speeds, parity checking, and discrete output type (Active Low or Active Open)
  • Device qualifies as simple and has no software or firmware
  • Internal watchdog timer to monitor validity of incoming ARINC data stream
  • Accommodates two additional external signal inputs with discrete output on “fail”
  • Reduces circuit complexity, size, weight, and installation labor

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.
