DS2690 Digital I/O Board

用于车身场景的 MultiCompact 板卡

DS2690 在 SCALEXIO 硬件在环仿真器中用于实现信号测量及信号生成。它提供了数字 I/O 通道,例如数字输入、PWM 输入或数字输出和PWM 输出。

应用领域

DS2690 Digital I/O Board 是专门为车身电子 ECU 硬件在环 (HIL) 仿真定制的 SCALEXIO 解决方案。车身应用(如电动车窗升降和挡风玻璃雨刷器等)要求具有大量大电流数字 I/O 通道以及故障仿真能力。DS2690 与 SCALEXIO 系统之间采用了电气隔离。

主要优点

DS2690 为信号生成与测量提供大量专用数字 I/O 通道。它们支持的 I/O 功能可以完全满足车身电子 ECU 的需求。实际负载可单独连接至每个通道。板载故障路由单元 (FRU) 可以确保在所有通道上进行故障仿真。

I/O 功能


DS2690 提供了预定义的数字输出通道,数字输入通道,以及可独立配置的数字通道。信号测量和生成通道可配置为:


  • 数字输入
  • PWM 输入或数字输出
  • PWM 输出

信号类型和通道并联通过 ConfigurationDesk 进行配置。


采用真实负载获取实际电流


测试 ECU 有时需要实际电流,因此可以在外部连接真实负载,也可以在内部使用替代负载。
