RDAC 912IS, MGL RDAC FOR ROTAX 912 IS ENGINE

The RDAC CAN module connects to the EFIS CAN bus and the CAN bus of an engine ECU system. The first model release caters for the Rotax 912iS engine which has two ECU systems and uses the CAN Aerospace data format.

The RDAC CAN connects to both data lanes of the Rotax 912iS (ECU A and ECU B) and continues to provide engine data from lane B in case of a lane A data failure depending on user selection of the DIP switches.

The RDAC CAN can be configured as “lane exclusive” – in this mode it can be fixed to a particular lane of the Rotax 912iS. The RDAC CAN emulates RDAC 1 (Lane A) and RDAC 2 (lane B). For twin engined applications, RDACs 3 and 4 can be emulated in similar fashion.

The RDAC CAN further provides two fuel level sender inputs, one fuel pressure sender input and a current sensor input.
The fuel level sender inputs are compatible with resistive fuel senders but can also be used with any fuel level sender that can provide a DC output in the 0-3V range (internal pull-up resistors used for the resistive level senders can be switched off).
The current sensor input provides for a system that provides a zero current voltage of 2.5V with a range of 2.5V above/below this value. The fuel pressure sender input accepts a 0-5V or 0.5-4.5V sender input range such as the popular senders available from UMA
