EDC-33 Overview

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.

Just about to begin flying with the EI MVP-50P, so no in-flight feedback yet. But I did study the user manual, then sat in my plane going through the screens, menus, etc. It was very easy and intuitive to locate everything, so I’m confident that it will become second nature to do this in flight… Very happy with all interactions with EI.

Much better quality with the bezel and buttons and knobs [vs. competition]. Also much easier to navigate and add fuel.

EI representatives… have been very helpful, truthful, and knowledgeable… We had no idea, that a few weeks later [after our purchase], we would need to have a Top Overhaul. What great timing! Having your engine monitor installed in our plane will hopefully help us keep it out of the shop for further engine repairs.
