DS2680 I/O Unit

MultiCompact unit for powertrain and vehicle dynamics scenarios

The DS2680 I/O Unit is a MultiCompact 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. It provides a high number of channels that can be easily configured by software.

Most of the I/O channels of the DS2680 have a fixed function, i.e., they are dedicated analog or digital channels. With its predefined channels, the DS2680 has an attractive price, and is ideal for specific application scenarios. Together with a SCALEXIO system, the DS2680 is galvanically isolated.

 

I/O Functionality

The DS2680 has numerous I/O channels, each with a mostly predefined function. You can choose between analog and digital inputs and outputs, resistance simulation channels, and special I/O channels. Signal measurement and generation can be time-triggered or angle-triggered.

 

Testing Electrical Failures

The DS2680 includes a Failure Insertion Unit (FIU) for testing ECU behavior in the event of a failure. 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 fail rails.

 

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.

 

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.
