Product Description
The AAI543-H50/K4A00 is a high-performance 16-channel analog output module for the Yokogawa CENTUM VP and CS 3000 control systems. This model supports HART digital communication, enabling bidirectional data exchange with intelligent field devices while maintaining precise analog control.
Designed for high-reliability and redundant system architectures, the module ensures fast and stable output switching during redundancy changeover, preventing process disturbances. It provides full galvanic isolation between output channels and system logic, protecting the DCS core from field-side electrical noise and faults.
This variant includes the factory-installed K4A00 adapter (ATK4A-00), featuring a KS Cable Interface for direct connection to AEA4D terminal boards, significantly simplifying field wiring and reducing installation complexity.

Application
The AAI543-H50/K4A00 is widely used for driving control valves, actuators, and variable frequency drives (VFDs) in demanding industries such as petrochemical processing, pharmaceutical manufacturing, and water treatment facilities.
Its HART pass-through capability makes it particularly suitable for systems implementing predictive maintenance, remote diagnostics, and online device calibration.
Frequently Asked Questions
Q: Can the AAI543-H50/K4A00 be used in hazardous (Ex) areas?
A: No. This variant (code 5) is intended for non-explosion-protected environments. For hazardous area applications, a model with appropriate intrinsic safety or explosion-proof codes must be selected.
Q: Is the K4A00 adapter supplied separately or pre-installed?
A: The /K4A00 suffix indicates that the KS Cable Interface Adapter is factory-installed, ready for direct connection to AEA4D terminal boards.
