The AMM32T (incorporating part number AMM32T) is a high-density temperature acquisition component designed for the Yokogawa CENTUM VP and CENTUM CS distributed control systems (DCS). This multiplexer module provides 32 isolated measurement channels, allowing for the consolidation of a large volume of Resistance Temperature Detector (RTD) signals into a single I/O footprint. It is engineered for industrial process monitoring, specifically where high-precision thermal tracking of reactor beds, bearing temperatures, or motor windings is required.

| System Integration | Native support for Yokogawa CENTUM VP and CENTUM CS 3000 controllers |
| Expansion Capability | Designed to operate alongside the AMT16R 16-channel expansion units |
| Physical Dimensions | 12.7 cm x 10.2 cm x 22.9 cm |
| Net Weight | 0.8 kg |
The AMM32T utilizes advanced multiplexing circuitry to scan 32 field sensors rapidly without compromising accuracy. By centralizing the temperature inputs, it significantly reduces the cost per point for large-scale installations. Its robust design is built for 24/7 continuous operation in harsh industrial environments, featuring diagnostic capabilities that report sensor burnout or wiring faults directly to the DCS operator interface.
Q: Does the AMM32T support 4-wire RTD sensors for ultra-high precision?
A: The standard AMM32T configuration is optimized for 3-wire RTD inputs, which provides sufficient lead-wire compensation for most industrial distances. For 4-wire requirements, verify the terminal block configuration and DCS software scaling parameters.
