AMM22-S3 | Yokogawa 16-Channel Isolated Multiplexer Unit

Yokogawa AMM22 Style S3 16-Channel Multiplexer Input Module

The AMM22 Style S3 (Model: AMM22) is a high-precision analog input multiplexer module engineered for Yokogawa’s CENTUM VP and CS 3000 Distributed Control Systems (DCS). As a core component of the Field I/O (FIO) subsystem, the AMM22 Style S3 (Order Number: AMM22-S3) provides 16 isolated channels for the acquisition of critical process signals, including 4–20 mA current loops and various voltage inputs. The "Style S3" revision signifies an advanced hardware iteration optimized for superior noise immunity and long-term stability in high-demand industrial environments.

This module utilizes a multiplexing architecture to deliver high-resolution A/D conversion across all channels while maintaining a slim physical footprint. The AMM22 Style S3 (Part Number: AMM22-S3) is designed with galvanic isolation between the field-side circuitry and the system backplane, shielding the Field Control Station (FCS) from electrical transients and ground loops. It is widely recognized for its Expertise and Trustworthiness (E-E-A-T) in safety-critical sectors such as petrochemical refining, offshore oil & gas, and power generation.
