Product Description
The AAI143 (P/N: AAI143-S50/ATA4S-00) is a high-density 16-channel analog input module for the Yokogawa CENTUM VP and CS 3000 DCS platforms. It is designed for precise acquisition of 4 to 20 mA signals from field transmitters measuring flow, pressure, temperature, and other process variables.
Each channel is galvanically isolated, providing protection against ground loops, electrical noise, and surges, ensuring high signal integrity in demanding industrial environments. The ATA4S-00 suffix incorporates an integrated Pressure Clamp Terminal Block, allowing direct field wiring without external terminal boards or KS cables. The S50 designation identifies this as a Standard Type module, optimized for reliable analog performance in non-explosion-proof environments.

FAQ
What is the difference between S50 and H50 modules?
-
S50: Standard 4–20 mA analog input
-
H50: Adds HART digital communication for remote diagnostics and smart instrument management
Does the module power 2-wire transmitters?
-
The module functions as a current sink. Loop power for 2-wire transmitters must be supplied externally via the system or terminal block configuration.
