AI895 3BSC690089R1
The AI895 3BSC690089R1 is a high-performance analog input module developed by ABB, specifically designed for accurate acquisition and processing of analog signals in industrial automation systems. It is widely applied in process industries such as chemical, oil and gas, power generation, and pulp and paper, serving as a critical link between field sensors and control systems.
In a chemical plant’s reactor control system, this module
can simultaneously collect analog signals from multiple sensors, including temperature (via thermocouples like K, J, or T type), pressure (4-20mA from pressure transmitters), and liquid level (0-10V from level transmitters). Equipped with advanced signal conditioning technology, it filters out electromagnetic interference from nearby pumps and valves, ensuring the signal-to-noise ratio is enhanced by over 50%. The processed data is transmitted to the DCS, enabling precise control of reactor parameters—for example, maintaining the reaction temperature within ±0.1℃, which is crucial for ensuring product quality consistency in batch production.In a power plant’s turbine control system, it excels in handling low-level signals from vibration sensors and pressure transducers. Its high-resolution ADC (Analog-to-Digital Converter) with 24-bit resolution allows it to detect minute signal changes as s
