DS2211 HIL I/O Board

Central I/O board for hardware-in-the-loop simulation

The DS2211 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. It combines a variety of typical HIL I/O and contains signal conditioning for 12 V, 24 V, and 48 V automotive systems and supports 2-voltage systems.

Key Benefits

The DS2211 HIL I/O Board is the central I/O board for hardware-in-the-loop simulation, especially in the field of automotive electronics. The DS2211 HIL I/O Board is tailored to the simulation and measurement of automotive signals, particularly for engine and vehicle dynamics applications, and combines a variety of typical HIL I/O signals on one board. The board contains signal conditioning for typical signal levels of 12 V, 24 V, and 48 V automotive systems and supports 2‑voltage systems.

Building a HIL Simulator

Together with a processor board (the DS1005, DS1006 or DS1007), the DS2211 HIL I/O Board constitutes the hardware core of dSPACE Simulator. The processor board performs the calculation of the real-time model, for example, of an engine, while the DS2211 measures and stimulates all the required I/O signals. The simulator can be expanded from 8 cylinders to up to 96 cylinders by using two or more DS2211 HIL I/O Boards.

Angular Processing Unit

The DS2211 HIL I/O Board features a unique angular processing unit that supports high-speed generation and measurement of crank angle-related signals to simulate engines up to 29,000 rpm.

Angle-Synchronous Cascading

For tougher I/O requirements, several boards, for example, several DS2211s, can be cascaded. The boards operate angle-synchronously if their time base connectors are connected. One DS2211 board acts as the time base (angle master), and the other boards read out its time base, which allows signals to be generated and measured angle-synchronously on several boards. The same applies to the DS4002 Timing and Digital I/O Board, the DS5001 Digital Waveform Capture Board, and the DS5203 FPGA Board, which can all be connected to the time base as well.
