How many engines can a single EMU-1 support?

← Back

The EMU-1 now supports multiple engine instances and two engines can be monitored using a single EMU-1 provided the following conditions are met:

  1. There are sufficient inputs i.e. using an EMU-1 for two engines implies that 3 gauge and 2 alarm inputs per engine are sufficient
  2. The EMU-1 is powered from the same supply which powers the gauges; and the gauges for both engines share this same power supply or
  3. If no gauges are used then the engines need to share a common ground

Otherwise a separate EMU-1 for each engine should be used.
