    Abstract: A multiplexed input/output (I/O) system detects leakage currents on a selected input channel. The system includes a leakage detection multiplexer connected to provide an output selected from one of a plurality of input channels. In addition, the leakage detection multiplexer provides as part of the output measured leakage currents associated with the selected input channel. Based on the detected leakage currents, a determination can made regarding whether the detected leakage currents have compromised the integrity of the multiplexer output. In addition, the detected leakage current can be used to compensate the output provided by the multiplexer to account for the presence of leakage currents on the selected channel.

    Abstract translation: 多路复用输入/输出（I / O）系统检测选定输入通道上的泄漏电流。 该系统包括被连接以提供从多个输入通道之一中选择的输出的泄漏检测多路复用器。 此外，泄漏检测多路复用器提供了与所选输入通道相关的输出测量泄漏电流的一部分。 基于检测到的泄漏电流，可以确定检测到的泄漏电流是否损害了多路复用器输出的完整性。 此外，检测到的泄漏电流可用于补偿多路复用器提供的输出，以解决所选通道上存在泄漏电流的情况。
