Aviation's Panel Mount Avionics Installation Leader

The EMS-D120 is a large screen Engine Monitoring System (EMS) that blends traditional analog gauges with newer digital technologies. TheEMS-D120 replaces up to 16 different types of gauges which are displayed on a stunning 7” diagonal color screen. The sunlight readable,color display and softkey menu system result in a user-friendly instrument that enhances overall safety and peace of mind.

Whatmakes the EMS-D120 so powerful is its ability to continuously monitor up to 27 available sensor inputs that cover the engine, fuel and othermiscellaneous systems and annunciate any abnormality immediately upon detection. This constant scan significantly reduces the pilotsworkload while providing a more thorough and consistent review.

A split-screen display environment provides pilots with anexcellent overview of the system coupled with additional pages of auxiliary information all available upon demand. Each of the color graphicpages are designed to promote easy visual scanning for interpretation of the current measurements relative to their normal/abnormaloperational limits.

Unlike many other similar systems, Dynon's EMS-D120 is easy to setup while simultaneously supporting a highdegree of configurability to accommodate a variety of different engines and pilot preferences. The default boot-up or start-up screenexample depicted above contains two separate pages on a split-screen format. During the initial setup, installers determine which gauges areindicated, their operational ranges, and whether an alarm is manifested along with its behavior. Info Items may be added to present thespecific needs of the particular engine, aircraft or pilots preferences.

This degree of engine specific and pilot preferentialcustomization when combined with a multi-page type of display and pilot configured checklists all add up to provide a unique presentationtailored to fit almost any need.

Dynon offers a variety of probes to accompany the EMS-D120 instrument with very attractivepackage pricing. The probes offered by Dynon are optimized to support a variety of engines including Lycoming, Continental, Rotax, andJabiru. Probes may also be purchased individually to monitor other engine types not specifically accommodated for by Dynon's probe packages.

Airplanes with existing engine sensors may already be compatible with the Dynon EMS-D120 system. The EMS-D120 was designed withthe intention of retrofitting some of the previously popular, non graphical systems like Grand Rapids EIS systems and Rocky Mountain Inc,Micro Monitors. While not 100% backward compatible, replacement costs are minimized to the extent possible.
