现场控制或检测元件输入给PLC各种控制信号，如限位开关、操作按钮、选择开关以及其他一些传感器输出的开关量或模拟量等，通过输入接口电路将这些信号转换成CPU能够接收和处理的信号。输出接口电路将CPU送出的弱电控制信号转换成现场需要的强电信号输出，以驱动电磁阀、接触器等被控设备的执行元件。输入接口用于接收和采集两种类型的输入信号，一类是由按钮、转换开关、行程开关、继电器触头等开关量输入信号；另一类是由电位器、测速发电机和各种变换器提供的连续变化的模拟量输入信号。直流输入接口电路为例，R1是限流与分压电阻，R2与C构成滤波电路，滤波后的输入信号经光耦合器T与内部电路耦合。当输入端的按钮SB接通时，光耦合器T导通，直流输入信号被转换成PLC能处理的5V标准信号电平(简称TTL)，同时LED输入指示灯亮，表示信号接通。微电脑输入接口电路一般由寄存器、选通电路和中断请求逻辑电路组成，这些电路集成在一个芯片上。交流输入与交直流输入接口电路与直流输入接口电路类似。
