Data Acquisition Units

Today's advanced Aviation and Military fleets require complex signal interfacing. At PDS, our team of experienced engineers have been designing and building Data Acquisition Units for analog and digital avionics input signals for decades. These avionics I/O computers seamlessly interface with multi-function cockpit displays, flight data recorders, FADECs, air data computers, maintenance computers and much more. 
In addition, our highly configurable systems are lightweight, rugged and are designed to survive the extreme heat, sub-zero cold and harsh vibrations demanded by modern jets, turboprops, helicopters, UAV / UAS and military tactical vehicles.
