Product Description
The Yokogawa AAI143-H00 S1 is a high-performance analog input module designed for distributed control systems such as CENTUM VP, CENTUM CS 3000, and ProSafe-RS. It ensures accurate and stable signal acquisition from field instruments like temperature sensors, transmitters, and flow meters, supporting precise process monitoring and control.
This module accepts multiple input types including 4–20 mA, 0–20 mA, 1–5 V, 0–5 V, RTD, and thermocouples, making it adaptable to diverse industrial requirements. In addition, it provides channel-to-channel and channel-to-ground isolation, which enhances noise immunity and ensures safe, stable operation. Its Delta-Sigma A/D converter delivers superior resolution and minimal drift, even in environments with high electrical interference.
The AAI143-H00 S1 has been succeeded by AAI143-H50/K4A00, offering the same reliability with improved digital communication (HART support) and integration flexibility.

FAQ
Q1: What is the difference between AAI143-H00 S1 and AAI143-H50/K4A00?
A1: The AAI143-H50/K4A00 is an upgraded model that includes HART digital communication and improved compatibility with Yokogawa’s KS cable adapter.
Q2: Can this module be used in a redundant DCS setup?
A2: Yes. It supports redundant configurations in CENTUM VP and ProSafe-RS systems for improved reliability.
Q3: Does the AAI143-H00 S1 support thermocouple and RTD inputs directly?
A3: Yes. It supports both RTD and thermocouple sensors without requiring external converters.
Q4: What is the recommended replacement if AAI143-H00 S1 is discontinued?
A4: Yokogawa recommends AAI143-H50/K4A00 as the direct replacement.
Q5: How can I confirm compatibility with existing terminal boards?
A5: For connection with AEA4D terminal boards, use the /K4A00 option with the ATK4A-00 KS Cable Interface Adapter.
