IC693MDR390LT 可檢測(cè)到如下故障：

復(fù)位

校準(zhǔn)存儲(chǔ)器錯(cuò)誤

SPI CRC錯(cuò)誤

ADC錯(cuò)誤

電源錯(cuò)誤

溫度錯(cuò)誤

開(kāi)路/短路錯(cuò)誤

這些功能允許用戶遠(yuǎn)程排除系統(tǒng)中發(fā)生的任何故障。在現(xiàn)有許多系統(tǒng)中，傳感器和執(zhí)行器可能位于遠(yuǎn)離控制室的潛在危險(xiǎn)區(qū)域。此外，擁擠的布線也可能導(dǎo)致難以確定哪些電纜連接到哪個(gè)傳感器或執(zhí)行器，使得這些系統(tǒng)的重新接線成本高昂且耗時(shí)。AD74413R模塊提供可配置能力和診斷功能，可確定哪個(gè)傳感器或執(zhí)行器連接到哪個(gè)特定通道。

隔離電源和數(shù)據(jù)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(gè)元件，如圖4所示。使用單獨(dú)的隔離器來(lái)提供電源和數(shù)據(jù)隔離。元件數(shù)量增加帶來(lái)了電路板面積較大的問(wèn)題。
