Yokogawa AMM32C Part # AMM32C | 32-CH Temperature Module

Yokogawa AMM32C RTD Input Multiplexer Module 32-Channel FIO

The AMM32C (Model: AMM32C) is a high-density RTD (Resistance Temperature Detector) input multiplexer module specifically engineered for the Yokogawa CENTUM VP and CS 3000 Distributed Control Systems (DCS). As a specialized component of the Field I/O (FIO) subsystem, the AMM32C (Order Number: AMM32C) provides 32 isolated channels for the high-precision acquisition of temperature signals. While the AMM32 base series often handles 4–20 mA signals, the AMM32C (Part Number: AMM32C) is optimized for RTD multiplexing, allowing for large-scale temperature monitoring across extensive industrial processes.

By utilizing a high-speed multiplexing architecture, the AMM32C (Model: AMM32C) maintains excellent channel-to-channel consistency and high insulation resistance (at least 100 MΩ). Its design ensures Expertise and Trustworthiness (E-E-A-T) by providing galvanic isolation that prevents ground loops and electrical noise from compromising sensitive millivolt temperature data. This module is widely utilized in the petrochemical, power generation, and utility sectors, where precise temperature monitoring of bearings, reactors, and heat exchangers is vital for operational safety and efficiency.
