    The proven choice for classed, low-cost mechanical engines.

    The DCU 305 R3 LT is a class-approved engine panel for non-CANbus engines, and is the direct successor for the DCU 305 R2 in all variants.

    In addition, it combines the Classification Society requirements for separate monitoring and safety functions in one unit.

    There is another version of this panel, the DCU 305 R3, that includes a J1939 CANbus interface for engines equipped with an ECM.

    The panel can be configured to run in one of four main operating modes. These are:

    • Propulsion
    • Auxiliary
    • Emergency
    • Combined Auxiliary/Emergency

    The included wire terminal module RK-66 has multiple I/O channels, where some have fixed functionality and others are configurable to any available function or event.

    Expansion of physical I/O is available if necessary. The AK-6 unit adds six 4-20 mA channels and the MK-14 unit add 14 relay channels.

    Finally, configuring the panel is a breeze with the extremely user-friendly Windows software Rudolf R3. Configuration files from the DCU 305 R3 are fully compatible.
