Yokogawa AAI143-H00-S1 Analog Input Module
The Yokogawa AAI143-H00-S1 is a high-performance, high-density 16-channel isolated analog input module engineered for Yokogawa’s CENTUM VP and CENTUM CS 3000 Distributed Control Systems (DCS). This module acts as the critical interface between field instruments and your control network, converting standard 4 to 20 mA analog current signals into precise internal digital data. Equipped with dedicated HART communication support (indicated by the “-H” suffix code), the AAI143-H00-S1 enables simultaneous transmission of process variables and digital diagnostic data from up to 16 HART-compliant field devices. Built for high-availability environments, it features robust channel-to-channel isolation to protect system integrity against ground loops or electrical surges, and fully supports dual-redundant configurations to eliminate single points of failure in mission-critical process loops.
