Product Description
The Yokogawa AAI141-S00 S2 is a high-density 16-channel analog input module designed for the CENTUM VP Distributed Control System (DCS). It provides reliable acquisition of 4–20 mA current signals from field transmitters, converting them into precise digital data for real-time monitoring and control.
Built for mission-critical industrial environments, the AAI141-S00 S2 combines robust isolation, compact design, and enhanced long-term stability, making it a core component in high-availability control architectures.

Technical FAQ
Q: Can the AAI141-S00 S2 be used with 2-wire transmitters?
A: Yes. The module accepts 4–20 mA signals; however, loop power for 2-wire transmitters must be supplied externally or via a compatible power distributor, as this module uses a sink-type input.
Q: What does the S2 suffix indicate?
A: S2 denotes an updated hardware revision with improved reliability and environmental compliance, while remaining fully compatible with S1 versions.
