Yokogawa AAI141-S00/K400 Analog Input Module New In Stock

Overview

The Yokogawa AAI141-S00/K400 is a 16-channel analog input module developed for integration with Yokogawa’s CENTUM CS 3000 and CENTUM VP distributed control systems. It receives 4–20 mA analog current signals from field transmitters and converts them into digital signals for process control and monitoring. The “/K400” option code denotes a special calibration or factory configuration version designed for improved input precision and compatibility with specific process standards. This model is highly regarded for its accuracy, long-term reliability, and robust noise immunity, making it suitable for demanding applications in oil refining, power generation, and chemical processing.
