Yokogawa AMM32T 32-Channel RTD/TC Input Multiplexer Module | CENTUM VP DCS

Product Overview

The AMM32T (Model: AMM32T) is a high-density temperature input multiplexer engineered for Yokogawa’s CENTUM VP and CS 3000 Distributed Control Systems (DCS). Operating as a core component of the Field I/O (FIO) subsystem, the AMM32T (Order Number: AMM32T) provides 32 isolated channels for the high-precision acquisition of RTD (Resistance Temperature Detector) and Thermocouple (TC) signals. This module is designed to centralize large-scale temperature monitoring into a single FIO slot, offering an efficient alternative to multiple lower-density units and significantly reducing the system’s hardware footprint.

Each channel on the AMM32T (Part Number: AMM32T) features galvanic isolation between the field and the system, shielding sensitive millivolt inputs from electromagnetic interference, ground loops, and backplane noise. The "T" designation highlights its optimization for thermal signal processing, which includes integrated linearization and cold junction compensation for a wide variety of industrial sensors. This reliability makes it the standard choice for petrochemical refining, power generation, and utility sectors where the accuracy of temperature data is critical for reactor safety and turbine health.
