Product Description
The AAI141-H50/K4A00 is a high-density analog input module designed for the Yokogawa CENTUM VP and CS 3000 control systems. It interfaces with up to 16 field transmitters, converting 4–20 mA signals into data for the process controller. The module’s non-isolated (common ground) architecture maximizes space efficiency, making it ideal for high-channel-count installations where compact form factor and professional cabinet integration are critical.
This unit features HART digital communication, enabling the DCS to access secondary process variables and advanced diagnostics from smart field instruments. The supplied ATK4A-00 (K4A00) interface adapter allows the module to connect via a KS Cable, simplifying wiring and enhancing cabinet organization.

Application
The AAI141-H50/K4A00 is suitable for centralized monitoring and data aggregation in:
-
Refineries and petrochemical plants
-
Water and wastewater treatment facilities
-
Power generation stations
Its 16-channel density reduces the number of individual modules required, while HART support provides enhanced diagnostic visibility for predictive maintenance.
Frequently Asked Questions
What does “non-isolated” mean for this module?
All 16 channels share a common negative return. This saves space but requires careful attention to ground potential differences in field loops during installation.
Is the KS Cable Adapter (ATK4A-00) removable?
Yes. The K4A00 adapter mounts to the module front and provides standardized KS cable connectivity, replacing individual screw-terminal wiring for cleaner, high-density cabinet integration.
