EDC-33 Overview

EDC-33 Engine Data Converter Overview Diagram

The EDC-33 (Engine Data Converter) is sometimes referred to as a Data Acquisition Unit (DAU) and has a broad range of applications. Its main purpose is to monitor the probes, transducers and sensors mounted on the engine and airframe. It then processes this data and outputs it on a serial bus. This allows a Display Unit or MFD to display the data without having to perform the intense processing required in a set timeframe.Also, annunciators and status switches can be monitored.

The EDC-33 Engine Data Converter can be used on piston, turboprop or jet aircraft as well as helicopters. If an EEC or FADC system needs to be monitored, check out our BC-5 (Bus Converter).

Smart Conversions

Processed and Calibrated Data Out

  • Analog and pulse signals are received and processed using an array of algorithms that massage the data into readable engineering units.
  • The EDC can provide simple linear conversions or mapped linearization for non-linear inputs or complex calculations.
  • Processed data is output via a number of serial protocols.
  • A receiving display unit only has to display the processed data as it is received.

Optimal Solution for Custom Monitoring Applications

  • Bluetooth capable for wireless in-field calibration.
  • The formatted data provides an easy integration to any display head without further processing.
