Introduction
The Yokogawa AMM21T Thermocouple Input Multiplexer Module is a high‑performance signal acquisition unit engineered for industrial process control and monitoring systems. Designed to collect and condition multiple thermocouple signals, this module enables accurate temperature measurement across a wide range of field points within Yokogawa distributed control system (DCS) environments such as CENTUM VP or RIO architectures. Its multiplexing capability allows efficient utilization of I/O slots, reducing system complexity while maintaining reliable data throughput and precision.
This module is ideal for applications that require multiple temperature measurements with minimal wiring and robust signal integrity in harsh industrial conditions.
