适用于动力传动系统及车辆动力学场景的 MultiCompact I/O 单元

DS2680 I/O 单元是SCALEXIO 系统的 MultiCompact I/O单元,可以提供变速箱或车辆动力学 ECU 的硬件在环仿真所需的所有 I/O 通道。

应用领域

DS2680 I/O Unit是SCALEXIO 系统的 MultiCompact 单元,可以提供变速箱或车辆动力学 ECU 的硬件在环仿真所需的所有 I/O 通道。大多数 I/O 通道都有一个固定功能,即都有专用的模拟通道或数字通道。

主要优点

尽管设计紧凑,DS2680提供了大量的预定义通道,这些通道包含了FIU功能。DS2680具有如此卓越的功能,并且性价比高,因此成为了具体应用场景的理想工具。

组件变体

DS2680 可以带有集成总线板。集成总线板卡为LIN、CAN 及 FlexRay 总线协议分别提供了两个通道。如果您需要更多的或不同的总线通道,比如需要四个 CAN 通道,您可以选择 HighFlex 总线板卡作为替代组件或附加扩展。

I/O 功能

DS2680提供38个I/O功能,这些功能由不同的I/O通道支持。所有通道都在dSPACE ConfigurationDesk软件中以图形化的方式进行定义和配置。
