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.

Always a pleasure to do business with EI. Products ship rapidly. I have been using your products for 20+ years.
The OPT-1 is more readable than the factory Cessna oil pressure/temp gauges.

Installing [EI’s FP-5L] in my RV 6. . . owned an FP-5L 6 years ago in a Cessna 206 on floats in a commercial operation in Alaska. Getting every ounce of payload, and coming home across Cook Inlet with the Cessna gas gauges near or on empty, I spent a lot of time explaining the benefits of the Fuel flow gauge… and reassured my passengers there were 12 gallons of fuel on board. I’m a believer…
Great Service.
