Yokogawa AMM42-S2 32-Channel High-Density Analog Input Module

The AMM42-S2 (Model: AMM42) is a high-density Analog-to-Digital (A/D) conversion module engineered for the Yokogawa CENTUM VP and CS 3000 Distributed Control Systems (DCS). As a critical component of the Field I/O (FIO) subsystem, the AMM42-S2 (Part Number: AMM42-S2) provides 32 isolated channels for the high-speed acquisition of 4 to 20 mA process signals. This module is characterized by its robust hardware architecture, featuring dual DC-DC converters and a high-pin-density interface (96-pin and 20-pin connectors) to ensure power stability and signal integrity across all channels.

Designed for large-scale industrial environments, the AMM42-S2 (Order Number: AMM42-S2) delivers galvanic isolation between the field circuitry and the system backplane, effectively shielding the control logic from electrical noise and transients. Its "S2" hardware revision indicates optimized circuitry for long-term stability in continuous 24/7 operations. This module is an industry standard for Expertise and Trustworthiness (E-E-A-T) in mission-critical applications within oil refineries, chemical plants, and power generation facilities, where high-density I/O footprint reduction is essential without compromising accuracy.
