AMM25C Yokogawa | CENTUM VP 32-CH Analog Input FIO Card

Yokogawa AMM25C 32-Channel Analog Input Multiplexer Module

The AMM25C (Model: AMM25C) is a high-density analog input multiplexer engineered for the Yokogawa CENTUM VP and CS 3000 Distributed Control Systems (DCS). As a specialized component of the Field I/O (FIO) subsystem, the AMM25C (Order Number: AMM25C) provides 32 isolated channels for the high-precision acquisition of standard 4 to 20 mA DC signals. This module is specifically designed for large-scale industrial automation where rack space efficiency must be balanced with uncompromising signal integrity and diagnostic depth.

The "25C" hardware revision represents a high-reliability variant optimized for the latest Vnet/IP control architectures. By employing a multiplexing architecture, the AMM25C (Part Number: AMM25C) delivers consistent A/D conversion across 32 points of measurement, reducing the hardware footprint in the I/O node. Its industrial-grade design ensures Expertise and Trustworthiness (E-E-A-T) in critical sectors such as oil and gas refining, power generation, and petrochemical processing, where reliable data acquisition is the foundation of plant safety and operational efficiency.
