Yokogawa AAV141-S50 | CENTUM CS 3000 16-Channel Module

Product Overview

The AAV141-S50 (Model: AAV141) is a high-density voltage input module designed for Yokogawa’s CENTUM VP and CENTUM CS 3000 Distributed Control Systems (DCS). Operating within the FIO (Field Interface I/O) architecture, it serves as a cost-effective solution for acquiring signals from field instruments where channel-to-channel isolation is not a technical requirement. The AAV141-S50 (Part Number: AAV141-S50) provides 16 channels of high-speed data conversion, translating analog voltage inputs into deterministic digital values for process control logic.

By utilizing a non-isolated architecture, the AAV141-S50 (Model: AAV141) maximizes cabinet density and reduces per-point costs, making it ideal for large-scale monitoring of non-critical secondary loops. Despite its compact footprint, the module maintains the high accuracy and fast update cycles required for demanding industrial applications in chemical processing, power generation, and water treatment facilities.
