Yokogawa AAI143-S00 16-Channel Isolated Analog Input Module CENTUM VP

The AAI143-S00 (Model: AAI143) is a high-density analog input module designed for Yokogawa’s CENTUM VP and CS 3000 Distributed Control Systems (DCS). As a core component of the Field I/O (FIO) subsystem, the AAI143-S00 (Order Number: AAI143-S00) provides 16 isolated channels for acquiring 4 to 20 mA DC signals from field transmitters. This module is engineered to handle critical process variables—such as pressure, flow, and temperature—with high precision and deterministic data updates, ensuring stable operation in mission-critical environments.

The AAI143-S00 (Part Number: AAI143-S00) distinguishes itself with an exceptionally fast 10 ms data update period and robust galvanic isolation (1500 V AC), protecting the system backplane from field-side electrical surges. It offers versatile field connectivity, allowing each channel to be independently configured for 2-wire or 4-wire transmitters via physical setting pins. Built for long-term reliability, the module features advanced diagnostics and current limiting, making it an industry standard for oil & gas, petrochemical, and power generation automation.
