DS2202 HIL I/O Board1)

I/O hardware with signal conditioning

The DS2202 HIL I/O Board has been designed for hardware-in-the-loop simulation in automotive applications, and is tailored to the simulation and measurement of automotive signals. The board contains signal conditioning for typical signal levels of 12 V, 24 V, and 48 V automotive systems and supports 2-voltage systems.

The end of life for this product has been set. Please see the footnote for more detailed information.

  • Ideally suited to body electronics, transmission, and component tests
  • Lower-cost alternative to DS2211 HIL I/O Board, without signal processor and angular processing unit
  • High number of analog and digital channels

Key Benefits

The DS2202 HIL I/O Board has been designed for hardware-in-the-loop simulation in automotive applications, and is tailored to the simulation and measurement of automotive signals. The board contains signal conditioning for typical signal levels of 12 V, 24 V, and 48 V automotive systems and supports 2‑voltage systems. Typical use cases are body electronics, transmission, and component tests performed by automotive suppliers, or as an additional HIL I/O board in large powertrain and vehicle dynamics HIL applications.

Building a HIL Simulator

Together with a processor board (DS1006 or DS1007), the DS2202 HIL I/O Board constitutes the hardware core of dSPACE Simulator. While the DS2202 measures and generates the signals required, the processor board performs the calculation of the real-time model. Communication between the processor board and the I/O board runs via the peripheral high-speed bus (PHS++ bus). The DS2202 can be used in dSPACE Simulator Mid-Size and Full-Size.

1) Speed and timing specifications describe the capabilities of the hardware components and circuits of dSPACE products. Depending on the software complexity, the attainable overall performance can deviate significantly from the hardware specification.
2) Output swing referenced to ground, when DACx is connected to another potential than GND.

1)The end of life of the dSPACE PHS (peripheral high-speed) hardware for modular systems is planned for December 31, 2024. You can still buy the related products up to and including December 31, 2021. New Releases of dSPACE software will still support the dSPACE PHS hardware for modular systems until at least the end of 2023. After the end of life, no services of any kind will be available for these products. We advise against using the PHS hardware products in new projects. For new projects we recommend that you use SCALEXIO, the latest dSPACE technology for modular real-time systems.
