Product Overview

The AMM52 S1 is a high-density analog multiplexer module built for Yokogawa CENTUM VP Field Control Station (FCS). It scans and conditions multiple low-level analog field signals, routing selected measurements to the main processor board for closed-loop control, monitoring and logging. This S1 hardware revision features optimized noise rejection and stable multiplexing timing, reducing signal distortion from long instrument cables and plant electrical interference. It installs vertically inside the standard Yokogawa nest rack and supports hot swap replacement to avoid full segment shutdown. This module is widely used in refineries, chemical plants, power stations and pulp facilities for continuous analog variable acquisition.
