The AI3351 module is used to convert on-site analog signals into digital signals for processing and monitoring by the control system. It is part of the TRICONEX series of products and is commonly used in industrial automation control systems that require high safety and reliability, such as the petrochemical, power, metallurgical, and other industries.
Description
Technical Parameter
Input signal type: Supports multiple analog input signals, such as 4-20mA current signal, 0-10V voltage signal, etc.
Number of input channels: Generally, there are multiple input channels that can simultaneously collect multiple analog signals. Common configurations include 8 channels or 16 channels, depending on the module model.
Resolution: With a high resolution, such as 16 bits or higher, it can accurately convert analog signals into digital quantities to ensure measurement accuracy.
Accuracy: The measurement accuracy of the module is relatively high, usually at a level of ± 0.1% or higher, ensuring the reliability of the collected data.
Sampling rate: With a fast sampling rate, it can quickly sample and convert input signals to meet the requirements of real-time control systems.
Isolation characteristics: Optical or other isolation techniques are used between the input channel and the system to effectively prevent external interference signals from entering the control system, improving the stability and anti-interference ability of the system.
Functional Features
Diagnostic function: It has powerful self diagnostic function and can monitor the working status of the module in real time. If a fault is detected, an alarm signal can be issued in a timely manner, and relevant fault information can be uploaded to the control system for maintenance personnel to troubleshoot and repair.
Redundancy function: In some critical applications, redundant configuration is supported, which enables redundant data collection and processing by using two or more AI3351 modules to work simultaneously. When one module fails, another module can continue to work, ensuring uninterrupted operation of the system and improving its reliability and availability.
Configuration flexibility: Flexible configuration can be achieved through programming software. Users can set the input signal type, range, filtering parameters, etc. according to actual application needs to adapt to different on-site signals and control requirements.
