plc数字量和模拟量输入模块的区别是什么？一般来说我们把模拟量模块分为三种的:一是模拟量输入模块、二是模拟量输出模块、三是模拟量输入/输出模块。那数字量输入模块跟模拟量输入模块有什么区别呢？

一：PLC模拟量输入模块(模拟量输入模块)又称A/D模块，将现场由传感器检测而产生的连续的模拟量信号转换成PLC的CPU可以接收的数字量，一般多为12位二进制数，数字量位数越多的模块，分辨率就越高。

二：PLC模拟量输出模块。模拟量输出模块又称为D/A模块，把PLC的CPU送往模拟量输出模块的数字量转换成外部设备可以接收的模拟量（电压或电流）。模拟量输出模块所接收的数字信号一般多为12位二进制数，数字量位数越多的模块，分辨率就越高。而数字量模块就是检测外部开关量输入的状态

What is the difference between plc digital quantity and analog quantity input module? Generally speaking, we divide analog modules into three types: one is analog input module, the other is analog output module, and the third is analog input/output module. What's the difference between digital input module and analog input module?One: PLC analog input module (analog input module), also known as A/D module, converts the continuous analog signals generated by sensor detection on site into digital quantities that can be received by the CPU of PLC, which are generally 12-bit binary numbers. The more digital digits, the higher the resolution.Two: PLC analog output module. Analog output module, also known as D/A module, converts the digital quantity sent by the CPU of PLC into analog quantity (voltage or current) that can be received by external equipment. Generally, the digital signals received by analog output modules are mostly 12-bit binary numbers, and the modules with more digital digits have higher resolution. And the digital module is to detect the state of external switch input.
