B&R X20AI8321 16-Channel Analog Input Module - ±0.05% High-Accuracy PLC Interface for Process Control | Modbus RTU, TÜV-Certified

Product Identification and Basics

The X20AI8321, recognized by its material number, is an analog input module crafted by B&R. It serves as a fundamental component in industrial control systems. With 8 analog inputs, it offers substantial capacity for data acquisition. The module is designed to interface with various sensors that output current signals. Its 12 - bit digital converter resolution ensures a certain level of accuracy in converting analog signals to digital values, making it suitable for applications where precise data collection is required.

Technical Features

One of the notable features of the X20AI8321 is its input flexibility. It allows users to select between two current ranges: 0 to 20 mA and 4 to 20 mA. This adaptability makes it compatible with a wide range of sensors used in industrial settings, such as pressure sensors, flow sensors, and temperature sensors. The 12 - bit digital converter resolution, although not the highest in the market, still provides a reasonable level of precision. It can accurately capture and convert the incoming analog signals, enabling reliable data processing in industrial control systems.

Application - Oriented Advantages

In industrial applications, the X20AI8321 plays a crucial role. It can be widely applied in manufacturing processes, for example, in monitoring the pressure of pipelines or the flow rate of liquids. The ability to choose between the two current ranges allows for seamless integration with different types of sensors already installed in the system. The 8 - input configuration enables the simultaneous monitoring of multiple parameters, enhancing the overall efficiency of industrial control and data acquisition. Its accurate conversion capabilities contribute to better - informed decision - making in industrial operations.
