DS2202 HIL I/O Board

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.

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 (DS1005, 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.
