DC Fuel Flow to Frequency Converter

The DC Fuel Flow to Frequency Converter (630502) is designed to receive the analog Fuel Flow (FF) signal in the form of a DC voltage and produce a digital output signal with a frequency proportional to the FF signal. The digital output represents the engine fuel flow and is available for use by a standard fuel management system.

Part 630502 includes an install kit.
