The YOKOGAWA AAI141-H is the HART-enabled variant of the AAI141 analog input module for the CENTUM VP / CS 3000 distributed control system. The "-H" suffix specifically indicates support for HART digital communication, allowing configuration and diagnostics of smart field transmitters over the 4–20 mA loop.

The YOKOGAWA AAR145 is a 16-channel isolated RTD/POT input module for the CENTUM series distributed control system, designed for temperature measurement using RTD sensors and position feedback via potentiometers.
