对于继电器的“常开、常闭”触点，可以这样来区分：继电器线圈未通电时处于断开状态的静触点，称为“常开触点”；处于接通状态的静触点称为“常闭触点”。
可编程逻辑控制器简称PLC（英文全称：Programmable Logic Controller）。随着科学技术的发展，为适应多品种，小批量生产的需求而产生发展起来的一种新型的工业控制装置。
1．现场输入接口电路由光耦合电路和微机的输入接口电路，作用是PLC与现场控制的接口界面的输入通道。
2．现场输出接口电路由输出数据寄存器、选通电路和中断请求电路集成，作用PLC通过现场输出接口电路向现场的执行部件输出相应的控制信号。
常用的I/O分类如下：yuiopgkhg23
开关量：按电压水平分，有220VAC、110VAC、24VDC，按隔离方式分，有继电器隔离和晶体管隔离。
模拟量：按信号类型分，有电流型（4-20mA,0-20mA）、电压型（0-10V,0-5V,-10-10V）等，按精度分，有12bit,14bit,16bit等。除了上述通用IO外，还有特殊IO模块，如热电阻、热电偶、脉冲等模块。
按I/O点数确定模块规格及数量，I/O模块可多可少，但其最大数受CPU所能管理的基本配置的能力，即受最大的底板或机架槽数限制。
1987年国际电工委员会（IEC）颁布的PLC标准草案中对PLC做了如下定义：
“PLC是一种数字运算操作的电子的电子系统，专门在工业环境下应用而设计。它采用可以编制程序的存储器，用来在执行存储逻辑运算和顺序控制、定时、计数和算术运算等操作的指令，并通过数字或模拟的输入(I)和输出(O)接口，控制各种类型的机械设备或生产过程。”
