PLC 控制系统的设计中，虽然接线工作占的比重较小，大部分工作还是PLC 的编程设计工作，但它是编程设计的基础，只要接线正确后，才能顺利地进行编程设计工作。而保证接线工作的正确性，就必须对PLC 内部的输入输出电路有一个比较清楚的了解。

我们知道，PLC 数字输入模块为了防止外界线路产生的干扰（如尖峰电压，干扰噪声等）引起PLC 的非正常工作甚至是元器件的损坏，一般在PLC 的输入侧都采用光耦，来切断PLC 内部线路和外部线路电气上的联系，保证PLC 的正常工作。并且在输入线路中都设有RC 滤波电路，以防止由于输入点抖动或外部干扰脉冲引起的错误信号。

PLC 的输入电路，按外接电源的类型分，可以分为直流输入电路和交流输入电路；按PLC 输入模块公共端（COM 端）电流的流向分，可分为源输入电路和漏输入电路；按光耦发光二极管公共端的连接方式可分为共阳极和共阴极输入电路。

PLC control system in the design, although the proportion of the work of wiring smaller, most of the work of the PLC programming or design work, but it is the basis of Programming, as long as the wiring correctly, can be programmed to smooth the design work. Wiring work and guarantee the correctness, it is necessary to the PLC within the input and output circuits have a clear understanding.

We know that, PLC digital input module in order to prevent interference from outside lines (such as voltage spikes, noise interference, etc.) from the PLC work even non-normal components of the damage is, in general the input side PLC Optocoupler used to cut off the PLC Internal and external lines of electrical lines on the links, and ensure the normal operation of PLC. And the input line are provided in the RC filter circuit to prevent the importation of points Pulsed jitter or external interference caused by the wrong signal.

PLC input circuit, according to the type of
