Product Overview

The AMM25C (Model: AMM25C) is a high-density analog input multiplexer engineered for Yokogawa’s CENTUM VP and CS 3000 Distributed Control Systems (DCS). Operating as a specialized component within 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 maximizing rack space efficiency is critical without compromising signal integrity or diagnostic depth.

The "25C" hardware revision represents a high-reliability variant optimized for modern Vnet/IP control architectures. By employing a sophisticated multiplexing architecture, the AMM25C (Part Number: AMM25C) delivers consistent A/D conversion across 32 measurement points, effectively halving the hardware footprint compared to standard 16-channel cards. Its industrial-grade design ensures peak performance 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.
