2. Product Description
The KUC755AE105 3BHB005243R0105 module is a high-performance industrial analog input (AI) module developed by ABB, specifically engineered for the AC800M Series DCS. Its primary function is to collect, convert, and transmit analog signals from field sensors (e.g., temperature, pressure, flow, level transducers) to the AC800M controller, providing precise process parameter data for real-time control and monitoring.
Featuring 8 independent isolated input channels, the module supports multiple analog signal types (4-20mA, 0-10V, thermocouple, RTD) with 16-bit resolution, ensuring high measurement accuracy and compatibility with a wide range of industrial sensors. It adopts rugged industrial-grade hardware design with enhanced electromagnetic interference (EMI) resistance and wide environmental adaptability, enabling stable operation in harsh industrial environments (e.g., petrochemical plants, power stations, metallurgical facilities) with temperature fluctuations, vibration, and electrical noise.
Seamlessly integrating with ABB AC800M system components and Control Builder M engineering software, the module supports easy configuration, signal scaling, and fault diagnosis. It is widely used in process industries such as petrochemical, power generation, chemical processing, and water treatment, serving as a critical link between field sensors and the control system to ensure reliable and precise process control.
