Product Description
The AAI143 (P/N: AAI143-H00 S2) is a high-density, fully isolated analog input module for the Yokogawa CENTUM VP distributed control system. It provides 16 independent current input channels (4–20 mA), ensuring complete galvanic isolation between channels and the system logic to prevent ground loop interference in complex process environments.
As an H-suffix module, it features HART digital communication, allowing remote asset management and diagnostics from smart field transmitters. The S2 hardware revision improves component longevity and stability over earlier generations. Manufactured in Japan, this module is built for mission-critical sensing in industrial applications requiring both high precision and robust electrical isolation.

FAQ
What is the significance of the "S2" style code?
The S2 revision represents an updated hardware design, including improved thermal management and long-term reliability, while maintaining the same functional capabilities as the S1.
Does this module require a separate HART multiplexer?
No. Each channel has an onboard HART modem, allowing direct communication between the DCS and smart field devices without additional hardware.
