I/O模块的主要作用如下：

输入模块：AS-BDAU-204  用于接收和采集输入信号，这些信号可以来自各种开关、传感器等设备。输入信号有两类，一类是开关量输入信号，如按钮开关、行程开关等；另一类是模拟量输入信号，如电位器、热电偶等。输入模块还需要将这些不同的电平信号转换成数字信号，以便PLC的CPU能够接收和处理。

输出模块：AS-BDAU-204   用于接收PLC中央处理器处理过的数字信号，并将其转换成现场执行部件能接收的信号，以控制各种设备，如接触器、电磁阀、调速装置等。此外，输出模块还可以控制指示灯、数字显示器和报警装置等。

I/O模块通常具有光电隔离装置，以提高设备的抗干扰能力。在模拟量I/O模块中，通常采用隔离放大器；而在数字量I/O模块中，一般使用由光电三极管和发光二极管组成的光电耦合器。

此外，AS-BDAU-204   I/O模块还具有可靠性高、可扩展性强、易于维护、灵活性高等特点。它们支持多种通信协议和编程语言，可以方便地与其他控制系统配合使用。

The main functions of the I/O module are as follows:

Input module: AS-BDAU-204 is used to receive and collect input signals, which can come from various switches, sensors and other devices. There are two types of input signals, one is the switching input signal, such as button switch, travel switch, etc.; The other type is analog input signals, such as potentiometers, thermocouples, etc. The input module also needs to convert these different level signals into digital signals so that the PLC's CPU can receive and process them.

Output module: AS-BDAU-204 is used to receive the digital signal processed by the PLC central processor and convert it into a signal that can be received by the field executive parts to control various devices, such AS contactors, solenoid valves, speed regulating devices, etc. In addition, the output module can also control the indicator light, digital display and alarm device.

I/O modules usually have photoelectric isolation devices to improve the anti-interference ability of the device. In analog I/O modules, isolation amplifiers are usually used. In the digital I/O module, the photoelectric coupler composed of phototriode and light-emitting diode is generally used.

In addition, AS-BDAU-204 I/O module also has the characteristics of high reliability, strong scalability, easy maintenance and high flexibility. They support a variety of communication protocols and programming languages and can be easily used with other control systems.
