The IO module has the following main functions

Input Function

The IO module can receive input signals sent by external devices and convert them into digital or analogue signals for use by the computer system or control system. These input signals can come from a variety of sensors, such as temperature sensors, pressure sensors, photosensitive sensors and so on. By receiving and parsing these input signals, the system can monitor and control the external environment in real time.

Output Functions

The IO module is capable of converting the output signals generated by a computer system or control system into the form required by an external device. These output signals are typically used to control actuators such as motors, valves, lights, etc. By sending appropriate output signals to external devices, the system enables control and operation of the external environment.

Data Acquisition and Processing

The IO module is capable of acquiring data from external devices and transferring it to a computer system or control system for further processing. This enables the system to acquire environmental data, status information and user inputs in real time and make appropriate decisions or perform specific tasks based on these data.

Communication Interfaces

IO modules are usually equipped with different types of communication interfaces, such as serial interfaces (RS232, RS485), Ethernet interfaces, CAN bus interfaces, and so on. These interfaces enable IO modules to exchange data and communicate efficiently with computer systems or other external devices.
