Yokogawa AAI141-S00 STYLE S2 Analog Input Module

The Yokogawa AAI141-S00 S2 is a 16-channel analog input module designed for Yokogawa CENTUM VP DCS cabinets, providing expanded capacity to capture analog signals from field instruments. It accepts 4–20 mA and 1–5 VDC inputs (model-dependent), converts them with analog-to-digital processing at roughly 100 samples per second, and delivers data for real-time monitoring and control in the CENTUM VP system. This rack-mounted I/O module is typically used to acquire and monitor process signals from sensors and transmitters, enabling reliable signal acquisition in industrial environments such as oil & gas, chemical plants, power generation, and manufacturing. With an accuracy of about ±0.1% typical and typically non-isolated channels (model dependent), the AAI141-S00 S2 integrates into Yokogawa's control architecture to support expansion, replacement of failed I/O, or routine maintenance of signal paths. Common replacements include Yokogawa AAI143, AAB141, and AAI841 analog I/O modules.
