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.

Good to go! Excellent instructions and easy install. Outstanding instrument!
After a full IFR install on my Cessna 175, my two favorite instruments without question is the CGR-30 Combo set. Simple and customizable, the data is invaluable!

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.

[I chose EI because of its] Reputation and value.
Always very friendly and knowledgeable staff. Over time, I have purchased six different EI instruments for the two planes I own. The instruments are easy to install, very accurate, and dependable. EI has very stable and easy-to-operate instruments.
Your customer service is excellent and your products are top quality!
My interactions with EI were all very positive. When I ordered the Dual CGR 30 instruments I was told there would be about a 6 week delivery time. It took a little less than 4 weeks. I am extremely happy with the service and product.
Works Great!
