Yokogawa AAI143-h00 Analog Input Modules
Manufacturer: Yokogawa
Product Number: AAI143-H00
Category: Analog Input Module
Number of Channels: 16
Input Signal: 4-20 mA
Resolution: 16-bit
System Compatibility: CENTUM VP DCS
Application: Collecting current signals from pressure, temperature, and flow transmitters
Product Description
The Yokogawa AAI143-H00 is a 16-channel analog input module specifically developed for the CENTUM VP distributed control system. It is designed to collect 4–20 mA current signals from field devices such as pressure, temperature, and flow transmitters. This module ensures accurate signal acquisition and high noise immunity, making it ideal for critical process control in industries such as petrochemicals, power, water treatment, and pharmaceuticals.
With features such as hot-swapping, channel-to-channel isolation, high-resolution A/D conversion, and support for redundant configurations, the AAI143-H00 delivers reliability and performance even in demanding industrial environments. It also supports integration in safety instrumented systems (SIL2/SIL3).
Key Features
