DS2680 I/O Unit

MultiCompact I/O unit for powertrain and vehicle dynamics scenarios

The DS2680 I/O Unit is a MultiCompact I/O unit for the SCALEXIO system that provides all the I/O channels required for the hardware-in-the-loop simulation of transmission or vehicle dynamics ECUs. 

 

  • 140 channels for extensive I/O functions
  • Compact half 19" unit
  • Provides all basic functionalities for HIL tests

Application Areas

The DS2680 I/O Unit is a MultiCompact I/O unit for the SCALEXIO system that provides all the I/O channels required for the hardware-in-the-loop simulation, e.g., of transmission or vehicle dynamics ECUs. Most of the I/O channels have a fixed function, i.e., they are dedicated analog or digital channels.

Key Benefits

Despite the compact design, the DS2680 offers a high number of predefined channels that include FIU functionalities. The described features in combination with the unit’s attractive price, makes the DS2680 the ideal tool for specific application scenarios.  

Component Variants

The DS2680 is available with and without an integrated bus board. The integrated bus board provides two channels for each of the bus protocols LIN, CAN and FlexRay. If you need more or different bus channels, for example, four CAN channels, you can use a HighFlex bus board in addition or as an alternative.

I/O Functionality

The DS2680 provides 38 I/O functions that are supported by different I/O channels. The channels are defined and configured graphically with dSPACE ConfigurationDesk.

Testing Electrical Faults

The DS2680 includes a Failure Insertion Unit (FIU) for testing ECU behavior in the event of a fault. It can be used as a central FIU for the SCALEXIO system. Each channel has a failure routing unit (FRU) for switching the connection to the FIU via the failrails. 

Real Loads

Substitute loads can be plugged onto the DS2680 internally if required. An exchangeable load board is available for you to mount different plug-on loads. Real loads or large substitute loads can be connected externally via the load connector provided for them.
