It often happens that vehicle devices or parts of bodybuilder fittings interact (power, signals, data) with the vehicle's electronic system. The interaction happens through one or more connectors. The typology of interaction depends of the number of equipments managed, their task, the quality and the quantity of information exchanged.
For the simplest applications it is sufficient to adopt a series of connectors from which it is possible to get basic information (Engine on / off; engine in running condition or stopped; handbrake engaged or disengaged; …).
For more complex fittings (Power Take-Offs, firefighting or ambulance equipments) multiple connectors and programmable control units are implemented. These advanced interface systems not only activate or disactivate one or more devices, but also protect them from bad operating conditions.
The main purpose of this article is to inform about the complete offer of connections and explain all the potential applications on IVECO Daily vehicles, minimizing the bodybuilder effort.
