Product Description

The MD23 series FLEX Custom Function Display (“CFD”) is a panel-mounted instrument capable of displaying various inputs in a configurable graphical presentation. FLEX is an off-the-shelf solution that is FAA and EASA TSO-approved with Level A design assurance software certification. FLEX has the ability to receive and send multiple types of inputs and outputs, allow user interface, and display custom designed graphics.

The unique Multi-I/O (MIO) feature allows twelve of the unit’s electrical inputs to be configured per the CID file to either accept or output various types of signals and information. MIO pins can be defined to be an analog input, a discrete on/off input, an analog output, or a discrete output.
