Magneti Marelli DDU310 Colour TFT Dash Logger

Overview

The DDU 310-DL32/64 is equipped with a complete range of analogue and digital inputs and ten-page liquid crystal display with configurable windows for an easily configured and personalised screen layout. A graphical bar indicator is typically used for representing engine revs.

A fast Ethernet bus is used for graphical layout load, channels’ configuration and data download. As part of the Magneti Marelli data acquisition and telemetry system, the DDU 310-DL32/64 (with internal data logger) can communicate over a CAN network with a range of additional data loggers receiving and displaying data from the logger as well functioning as an additional input module.
