Product Description

High-Precision Signal Multiplexing Overview

The AMM22-S3 (Model: AMM22) is a high-performance analog input multiplexer unit engineered for the Yokogawa CENTUM VP and CS 3000 Distributed Control Systems (DCS). As a pivotal component of the Field I/O (FIO) subsystem, the AMM22-S3 (Style Code: S3) provides 16 isolated channels optimized for the high-resolution acquisition of process variables. The Style S3 revision represents a significant hardware enhancement, offering superior noise immunity and thermal stability compared to earlier iterations. By utilizing a high-speed multiplexing architecture, this module delivers deterministic A/D conversion across all 16 channels, ensuring that critical data from pressure, flow, and level transmitters is digitized with minimal latency and maximum accuracy.
