滤波电路用以消除输入触头的抖动，光电耦合电路可防止现场的强电干扰进入pLC。由于输入电信号与pLC内部电路之间采用光信号耦合，所以两者在电气上完全隔离，使输入接口具有抗干扰能力。现场的输入信号通过光电耦合后转换为5V的TTL送入输入数据寄存器，再经数据总线传送给CpU。
出现输出故障时，首先应察看输出设备是否响应LED状态指示器。
若输出触点通电，模块指示器变亮，输出设备不响应。那么，首先
应检查保险丝或替换模块。若保险丝完好，替换的模块未能解决问
题，则应检查现场接线。若根据编程设备监视器显示一个输出器被命令接通，但指示器关闭，则应替换模块。
可编程序控制器(programmable Controller)原本应简称pC，为了与个人计算机专称pC相区别，所以可编程序控制器简称定为pLC(programmable Logic Controller)，但并非说pLC只能控制逻辑信号。pLC是专门针对工业环境应用设计的，自带直观、简单并易于掌握编程语言环境的工业现场控制装置。
在诊断输入／输出故障时，方法是区分究竟是模块自身的
问题，还是现场连接上的问题。如果有电源指示器和逻辑指示器，模块
故障易于发现。通常，先是更换模块，或测量输入或输出端子板两端电压
测量值正确，模块不响应，则应更换模块。若更换后仍无效，则可能是现
场连接出问题了。输出设备截止，输出端间电压达到某一预定值，就表明现
场连线有误。若输出器受激励，且LED指示器不亮，则应替换模块。如果
不能从I／O模块中查出问题，则应检查模块接插件是否接触不良或未
对准。最后，检查接插件端子??NCE COM/CTL MODULE REV.H 51401635150
