Product Introduction
The Yokogawa AMM11T Voltage Input Multiplexer Module is a high-performance analog input module designed for integration into Yokogawa’s CENTUM CS 3000 and other distributed control systems (DCS). Engineered to handle multiple analog voltage signals efficiently, the AMM11T consolidates readings from various voltage inputs and forwards them to a central processing unit for monitoring and control purposes. It is highly regarded for its precision, reliability, and ability to withstand harsh industrial environments, making it a vital component in process control systems across a wide range of industries.
With robust signal isolation, precise voltage detection, and hot-swappable design, the AMM11T enables engineers to monitor and control complex processes in power plants, petrochemical facilities, water treatment systems, and manufacturing industries. This module supports multiple channels, high-speed multiplexing, and integrates seamlessly with other Yokogawa modules and controllers.
