Yokogawa AAI143-S00/A4S00: 16-Channel Analog Input Module for DCS Systems

Overview

The Yokogawa AAI143-S00/A4S00 is a 16-channel analog input module designed for use in Yokogawa’s CENTUM VP and CENTUM CS Distributed Control Systems (DCS). It accepts 4 to 20 mA DC signals from field transmitters, converting them into accurate digital signals for processing by the DCS controller. This module is ideal for industries that require stable, continuous data acquisition from remote field devices.

The AAI143-S00/A4S00 comes with a non-isolated design, which means that the input and output circuits share a common ground. This setup makes it perfect for applications where field transmitters are powered by the same power supply as the DCS controller. It’s easy to integrate and cost-effective for such configurations.
