Product Introduction：

Overview

The Yokogawa AAI141-H53 is a high-performance 16-channel analog input module developed for use in Yokogawa’s CENTUM CS 3000 and CENTUM VP distributed control systems. It converts analog current signals (4–20 mA DC) from field instruments into digital data for process control and monitoring. The module provides isolated channels, precise signal processing, and built-in self-diagnostics, ensuring reliable operation in continuous process industries such as oil refining, petrochemical, and power generation.
