Product Description
The AAI141-H00/K4A00 is a high-performance 16-channel analog input module designed for Yokogawa CENTUM CS 3000 and CENTUM VP distributed control systems (DCS). It provides 4–20 mA current inputs, serving as the primary interface for field transmitters measuring pressure, flow, and level.
Engineered for high-speed signal processing and robust noise rejection, the module ensures accurate and timely data delivery to the Human Interface Station (HIS). The /K4A00 option specifies a dedicated KS-cable interface, enabling simplified wiring, improved maintenance access, and compatibility with redundant terminal boards.
This module is widely used in high-availability industrial systems, maintaining signal integrity and supporting secure, reliable process control.

Application Scenarios
The AAI141-H00/K4A00 is extensively used in continuous process industries, including:
-
Chemical refining
-
Water treatment
-
Pulp and paper manufacturing
It is ideal for high-density analog loops, concentrating multiple 4–20 mA signals into a single I/O node in CENTUM CS 3000 or VP systems, while supporting high-availability and redundant configurations.
Frequently Asked Questions
What is the difference between AAI141 and AAI143?
-
AAI141: Standard 16-channel module for 4–20 mA current inputs
-
AAI143: Typically for voltage inputs or alternative signal ranges
Does the /K4A00 option support redundancy?
Yes. The module can be installed in a dual-redundant configuration, connecting to redundant terminal boards to maintain all 16 measurement loops even if one module fails.
