Types of IO modules

Digital Input/Output Modules

Digital IO modules are used to handle the input and output of binary signals. They can receive and send digital signals and are commonly used to control logic switches, triggers and other digital devices.

Analogue Input/Output Modules

Analogue IO modules are used to process the input and output of continuous type signals. They can receive and send analogue signals and are typically used to measure and control continuity parameters such as temperature, pressure, voltage, etc.

Configuration Input/Output Modules

Configuration IO modules combine digital and analogue functionality to handle different types of input and output signals simultaneously. They typically offer greater flexibility and configurability for applications that require multiple signal types.

Special Function I/O Modules

Special function IO modules are designed and optimised for specific application areas. For example, high-speed data acquisition modules are used for high-speed data transmission and real-time data processing, industrial control IO modules are suitable for factory automation control systems, and security monitoring IO modules are suitable for security systems.

Working Principle of IO Modules

The working principle of IO modules is based on signal conversion and communication technology. They usually consist of input circuit, output circuit, signal conversion circuit and communication interface.

Input Circuit

Input circuits are used to receive signals sent from external devices and convert them into signals that can be read by a computer system or control system. These input circuits usually include filters, amplifiers and analogue-to-digital converters to ensure stable signal transmission and accurate data acquisition.

Output Circuits

Output circuits are used to convert signals generated by a computer system or control system into a form required by an external device. These output circuits usually include digital to analogue converters, current amplifiers and driver circuits etc. to ensure correct signal transmission and accurate execution of operations.

Signal Conversion Circuits

Signal conversion circuits are used to convert input signals to output signals accordingly. They can convert analogue signals to digital signals or vice versa. These conversion circuits typically include analogue-to-digital converters (ADCs), digital-to-analogue converters (DACs), comparators, etc.

Communication Interfaces

IO modules typically have various communication interfaces for exchanging data and communicating with computer systems or other external devices. These interfaces can be serial interfaces (RS232, RS485), Ethernet interfaces, USB interfaces, or CAN bus interfaces, among others.
