ABB NAIO - 03 Analog I/O Expansion Board​

Product Overview​

The ABB NAIO - 03 Analog I/O Expansion Board is an expansion module specifically designed for industrial automation control systems. Its purpose is to add more abundant analog input and output functions to the basic control system. This expansion board can be seamlessly integrated with a variety of programmable controllers and other automation equipment under ABB, significantly enhancing the system's ability to process analog signals. It is widely used in industrial scenarios that require precise analog control and monitoring, such as process control, manufacturing, and energy management fields.​

Functional Features​

Analog Input Function​

Support for Multiple Signal Types: The NAIO - 03 supports a variety of common analog input signal types, including 4 - 20mA current signals and 0 - 10V voltage signals. This wide compatibility allows it to easily connect to various sensors, such as pressure sensors, temperature sensors, and flow sensors, accurately converting on - site physical quantities into electrical signals and inputting them into the control system.​

High Resolution: This expansion board has a 16 - bit resolution, which can perform extremely fine quantization of input signals. This means that even small changes in signals can be accurately captured, providing high - precision data for the system. It ensures precise process monitoring and control in scenarios with high control accuracy requirements, such as chemical production and precision manufacturing.​

Number of Input Channels: It has multiple analog input channels, and the specific number varies depending on the model. Generally, it can provide 8 or 16 independent input channels. Each channel can work independently and collect data from different sensors at the same time, meeting the demand for multi - point analog monitoring in complex industrial environments.​

Analog Output Function​

Stable Output Signals: The NAIO - 03 can output stable 4 - 20mA current signals or 0 - 10V voltage signals, which are used to control various actuators, such as control valves and frequency converters. The stability and accuracy of its output signals ensure that the actuators can act precisely according to the instructions of the control system, realizing precise control of industrial processes.​

Output Accuracy: The output accuracy can reach ±0.1% FS (Full Scale), ensuring that the output signal highly matches the set value of the control system. In industrial production, this high - precision output plays a crucial role in maintaining the stability of the production process and ensuring product quality.​

Output Channel Configuration: Similar to the input channels, the number of output channels is also flexible, with common configurations of 4 or 8 output channels. Different output channels can be connected to different actuators respectively, realizing independent control of multiple devices and meeting diverse industrial control needs.​

Electrical Isolation and Anti - Interference Capability​

Electrical Isolation Design: To prevent on - site electrical interference from affecting the control system, the NAIO - 03 adopts electrical isolation technology in both input and output channels. Effective electrical isolation is achieved between input channels and output channels, and between channels and the system. The isolation voltage can generally reach 2500V AC, effectively avoiding data errors or equipment failures caused by electrical interference.​

Anti - Interference Measures: In addition to electrical isolation, the expansion board also adopts a series of anti - interference measures, such as shielding design and filter circuits. The shielding design can block the influence of external electromagnetic interference on the internal circuits of the board, and the filter circuits can filter the input and output signals to remove noise and clutter in the signals, ensuring the reliable operation of the system in complex electromagnetic environments.​

Easy Installation and Configuration​

Mechanical Installation: This expansion board adopts a standard DIN rail mounting method, which can be conveniently and quickly installed on the DIN rail of the industrial control cabinet. The installation process is simple and no special tools are required, greatly saving installation time and costs.​

Software Configuration: Through ABB's supporting programming software, users can easily configure the NAIO - 03. In the software, users can conveniently set parameters such as the type, range, and resolution of input and output channels, and also calibrate and diagnose the channels to ensure that the performance of the expansion board meets the actual application requirements. At the same time, the software provides an intuitive operation interface, so even non - professional personnel can quickly get started.​
