Product Description

The AAI143 (P/N: AAI143-H53/A4S00) is a high-performance analog input module for the Yokogawa CENTUM VP distributed control system. It provides 16 fully isolated current input channels (4–20 mA) for reliable monitoring of process variables.

The H-suffix enables HART digital communication, allowing the DCS to access multivariable data and diagnostics from smart transmitters without additional hardware. The A4S00 option equips the module with a high-reliability Pressure Clamp Terminal Block, allowing direct field wiring termination for secure connections even in high-vibration environments.
With its 53-suffix standard industrial configuration, the module combines high-density signal processing with robust electrical isolation, ensuring process integrity in demanding automation environments.

Technical Specifications

Application Use Cases

The AAI143-H53/A4S00 is ideal for oil & gas, pharmaceutical, and power generation applications.
Its 16-channel density makes it perfect for monitoring large transmitter banks, while the pressure clamp terminals allow direct wiring, easy maintenance, and flexible cable lengths in control cabinets.

FAQ

What is the advantage of the A4S00 terminal over the K4A00 adapter?
The A4S00 provides direct wire termination via a pressure clamp block. The K4A00 uses a cable adapter for pre-fabricated KS cables. A4S00 is preferred for custom wiring lengths or when bypassing intermediate terminal boards.

Can this module communicate with non-HART transmitters?
Yes. It functions as a standard 4–20 mA input module for conventional transmitters, while automatically supporting HART digital signals when connected to smart devices.
