The RDAC VD is the Engine monitor module used with E2, Ultra, Enigma, Odyssey and Voyager instruments. This device is intended for applications that require up to four channels of thermocouple temperature monitoring (The E2 package includes the RDAC VD).

The RDAC VT is very similar to the VD but provides a modified RPM input intended for turbine engines (primary RPM or N1).

The RDAC VD and VT provides up to 4 channels for thermocouple sensors (EGT,CHT), channels dedicated to NTC temperature probes, oil and fuel pressure, fuel levels, fuel flow and RPM.
