DS4002 Timing and Digital I/O Board1)

Generating and capturing digital signals

With the DS4002 Timing and Digital I/O Board, you can capture and generate a wide spectrum of digital signals for tasks during hardware-in-the-loop simulation and rapid control prototyping.

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

  • Captures digital signals for parameter measurement
  • Generates flexible pulse patterns
  • Comprehensive set of standard applications included

Key Benefits

The DS4002 Timing and Digital I/O Board combines a variety of digital I/O tasks on one board. It provides the functionality you expect from an ordinary digital I/O board plus additional features that help you perform specific control tasks easily. Eight channels can be programmed for either capturing digital signals or generating flexible pulse patterns. 32 additional I/O lines can be used for further digital I/O tasks, for example, to control single input lines (switches, sensors) or output lines (relays, displays).

Application Areas

The DS4002 Timing and Digital I/O Board is ideally suited to all kinds of hardware-in-the-loop simulations and rapid control prototyping. It captures digital signals for the measurement of parameters such as frequency or phase, and generates digital signals such as PWM pulses to control actuators or simulate sensors. It also performs many digital I/O tasks, for example, controlling switches or displays.

 
A brief overview of applications:
  • Frequency measurement (F/D)
  • PWM duty cycle measurement
  • Phase shift measurement
  • 1- and 3-phase PWM pulse pattern generation
  • Square-wave signal generation (D/F)
  • Monoflop signal generation

Further Features

The DS4002 Timing and Digital I/O Board can be used together with the DS2211 HIL I/O Board to capture engine signals angle-synchronously. The DS4002 can also be the time base (angle master) in such a setup. In many situations, the DS4002 board can be used as an alternative to the DS5001 Digital Waveform Capture and DS5101 Digital Waveform Output Boards.

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.
