模拟输入(AI) 模块由三个独立的输入通道组成。每个输入通道接收来自每个点的可变电压信号,将其转换为数字值,并将值传输到三个主处理器按需模块。在TMR模式下，然后使用中值选择算法来选择一个值， 以确保每次扫描的数据正确。每个输入点都经过感应,以防止..在一个通道 上执行单个故障的方式会影响另一个通道。每个模拟输入模块都保持完整，每个通道都经过连续诊断。任何诊断故障通道都会激活故障指示器模块,进而激活机箱报警信号。模块故障指示灯仅报告一个通道故障 ，不报告模块故障。模块故障表示两个故障通道可以正常运行多少个。模拟量输入模块支持热备份，可在线更换故障模块。模拟量输入模块需要一个单独的外部终端面板 (ETP) 通过电览连接到Tricon的底板。每个模块都有机械钥匙,用于正确安装Tricon机箱。 The Analog Input (AI) module consists of three independent input channels. Each input channel receives variable voltage signals from each point, converts them into digital values, and transmits the values to the three main processor on-demand modules. In TMR mode, then use the median selection algorithm to select a value to ensure the correct data for each scan. Each input point is sensed to prevent The way a single fault is executed on one channel can affect another channel. Each analog input module remains intact, and each channel undergoes continuous diagnosis. Any diagnostic fault channel will activate the fault indicator module, which in turn activates the chassis alarm signal. The module fault indicator only reports one channel fault and does not report module faults. Module failure indicates how many faulty channels can operate normally. The analog input module supports hot backup and can replace faulty modules online. The analog input module requires a separate external terminal panel (ETP) to be connected to the Tricon's backplane through an electrical circuit. Each module has a mechanical key for the correct installation of the Tricon chassis.
