DS2002/DS2003 Multi-Channel A/D Boards1)

Hochauflösende A/D-Boards

Die DS2002 und DS2003 Multi-Channel A/D Boards bieten verschiedene Auflösungen, Kanalanzahlen und Geschwindigkeiten für die A/D-Umwandlung. Die Boards werden zur Konvertierung analoger Spannungen oder Ströme von Sensoren (Druck, Temperatur etc.) oder von elektronischen Steuergeräten eingesetzt.

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

Anwendungsbereiche

Die A/D-Umwandlung ist Bestandteil der meisten Anwendungen in den Bereichen Rapid Control Prototyping und Hardware-in-the-Loop (HIL)-Simulation. Beim Rapid Control Prototyping stellen Sensoren für Druck, Temperatur oder andere Signale analoge Spannungen und Ströme bereit. Bei der HIL-Simulation liefert das elektronische Steuergerät analoge Spannungen oder Ströme, die den simulierten Aktor steuern.

Vorteile

Die A/D-Boards bieten eine unterschiedliche Anzahl von Kanälen, Auflösungen und Geschwindigkeiten. Die nachfolgende Tabelle gibt Ihnen einen ersten Überblick. Die Boards werden mit Real-Time Interface mit Simulink® konfiguriert. Sie können den Spannungsbereich und die Auflösung separat für jeden Kanal oder A/D-Wandler auswählen.

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.
