Product Introduction：

Overview

The Yokogawa AAI141-S00/A4S00 is a 16-channel analog input module designed for use in Yokogawa’s CENTUM CS 3000 and CENTUM VP distributed control systems. It converts analog 4–20 mA current signals from field transmitters into high-accuracy digital data for process monitoring and control. The “/A4S00” option indicates a specific configuration or calibration version tailored for extended signal handling performance and improved long-term stability. This module is widely used in industries such as petrochemical, oil and gas, and power generation where reliability and precision are essential.
