IC693MDR390LT 可檢測到如下故障:
復位
校準存儲器錯誤
SPI CRC錯誤
ADC錯誤
電源錯誤
溫度錯誤
開路/短路錯誤
這些功能允許用戶遠程排除係統中發生的任何故障。在現有許多係統中,傳感器和執行器可能位於遠離控制室的潛在危險區域。此外,擁擠的布線也可能導致難以確定哪些電纜連接到哪個傳感器或執行器,使得這些係統的重新接線成本高昂且耗時。AD74413R模塊提供可配置能力和診斷功能,可確定哪個傳感器或執行器連接到哪個特定通道。
隔離電源和數據解決方案
分立式方案
AD74413R的分立式隔離電源解決方案需要多個元件,如圖4所示。使用單獨的隔離器來提供電源和數據隔離。元件數量增加帶來了電路板面積較大的問題。
