Product Introduction
The Yokogawa AMM11 Voltage Input Multiplexer Module is a precision analog input module designed for high-performance process control and monitoring applications. As part of Yokogawa’s distributed control system (DCS) architecture, particularly the CENTUM and STARDOM series, the AMM11 serves as a critical interface between field devices and the system’s control processors. It enables the acquisition of multiple voltage input signals from sensors, transmitters, or other instrumentation sources, converting them into digital data for accurate control and analysis.
The AMM11 is built to handle multiple analog voltage inputs simultaneously, featuring high-resolution analog-to-digital conversion and excellent linearity. This allows the module to maintain measurement accuracy even under varying load or environmental conditions. It supports a wide range of voltage signal levels, offering flexibility for diverse industrial measurement needs.
Engineered with Yokogawa’s renowned reliability and diagnostic intelligence, the AMM11 ensures stable operation, self-diagnostics, and easy integration into existing system configurations. It is particularly suited for complex, safety-critical, or data-intensive process automation systems.
