Yokogawa AAI143-S00 16-Channel Isolated Analog Input Module

The AAI143-S00 (Model: AAI143) is a high-performance analog input module designed for Yokogawa’s CENTUM VP, CENTUM CS 3000, and ProSafe-RS control systems. Engineered as a standard type acquisition unit, the AAI143-S00 (Order Number: AAI143-S00) provides 16 isolated channels for processing 4 to 20 mA DC signals from field transmitters. This module is essential for precise monitoring of critical process variables such as pressure, temperature, and flow in high-availability industrial environments.

What distinguishes the AAI143-S00 (Part Number: AAI143-S00) is its robust galvanic isolation and high-speed data update period of 10 ms, which ensures that the DCS (Distributed Control System) receives real-time, interference-free data. The module supports both 2-wire and 4-wire transmitter configurations, adjustable via on-board pins for each individual channel. With an accuracy of ±16 µA and a withstanding voltage of 1500 V AC, it represents Yokogawa’s commitment to Expertise and Reliability (E-E-A-T) in process automation and safety instrumented systems (SIS).
