The DS2642 is used in SCALEXIO hardware-in-the-loop simulators. It provides a central Failure Insertion Unit and power switches for HIL tests of ECUs.
The DS2642 FIU & Power Switch Board combines two components:
The DS2642 offers 10 switchable software-configurable channels, that can be bundled for increasing the current possible.
The central FIU on the DS2642 is connected to the failure routing units of the I/O boards via the failrails. It switches the failures for the channels on the boards.
The following options are available:
The failures are prepared on the I/O boards by relays, and failure insertion is performed by semiconductor switches on the central FIU. The result is a fast switching frequency that enables loose contacts to be simulated.
The power switch provides 10 switchable channels, which supply current to the external devices such as ECUs and loads. The current can be measured simultaneously. The central FIU can also use the power switch channels to simulate short circuits to the supply to the ECU. The channels can be bundled to increase the current and are selected in ConfigurationDesk. Several DS2642s can be used in one SCALEXIO system.
The power consumption of the connected components can be measured precisely on each power switch channel.
