DS210x D/A Boards

Schnelle D/A-Umwandlung

Bei vielen Regelanwendungen ist die D/A-Umwandlung für die Ansteuerung der Aktoren notwendig. Die DS210x D/A Boards bieten eine unterschiedliche Anzahl von Kanälen, Auflösungen und Geschwindigkeiten.

Anwendungsbereiche

Bei vielen Rapid-Control-Prototyping-Anwendungen ist die D/A-Umwandlung für die Ansteuerung der Aktoren notwendig. Bei Hardware-in-the-Loop-Anwendungen müssen Sensoren, die analoge Signale bereitstellen, simuliert werden.

Vorteile

Die D/A-Boards bieten eine unterschiedliche Anzahl von Kanälen, Auflösungen und Geschwindigkeiten. Die nachfolgende Tabelle gibt einen ersten Überblick. Alle drei Boards können mit Real-Time Interface in Simulink® konfiguriert werden. Der Spannungsbereich für jeden Kanal lässt sich separat festlegen.

Board Kanäle Auflösung Abtastzeit 1)
DS2101 D/A Board 5 out 12 bit 3.0 μs
DS2102 High-Resolution D/A Board 6 out 16 bit 1.6 μs
DS2103 Multi-Channel D/A Board 32 out 14 bit 10.0 μs

1) Angaben zu Zeit und Geschwindigkeit beschreiben die Möglichkeiten der Hardware-Komponenten und Schaltkreise von dSPACE Produkten. Abhängig von der Komplexität der Software kann die erreichbare Gesamtleistung deutlich von den Hardware-Spezifikationen abweichen.
