Product Description
High-Availability Isolated Analog Acquisition
The Yokogawa AAI143-H50 S1 is a high-performance, 16-channel isolated analog input module designed for the FIO (Field I/O) subsystem of CENTUM VP and CS 3000 Distributed Control Systems. This "S1" bundle is factory-equipped with the ATK4A-00 (or K4A00) KS Cable Interface Adapter, providing a robust, plug-and-play solution for high-density cabinet wiring. The module is engineered to acquire 4–20 mA signals from both 2-wire and 4-wire transmitters, featuring complete channel-to-channel galvanic isolation to eliminate ground loop interference and ensure signal integrity in electrically noisy environments.
HART Digital Communication
The AAI143-H50 designation signifies integrated HART digital communication capability. This allows the module to pass-through complex device variables and diagnostic data from "smart" field instruments directly to the DCS maintenance station. By supporting the HART protocol, the AAI143-H50 S1 enables advanced asset management, remote configuration, and predictive diagnostics without the need for additional handheld communicators or external multiplexers.
