Product Description
The Yokogawa AMM12C Voltage Input Multiplexer Module is a high-performance analog signal interface used in CENTUM VP and CENTUM CS distributed control systems. Designed for precision and reliability, it enables the acquisition of up to 16 independent DC voltage signals from field devices and transmits them to the control processor for real-time analysis.
Its dual-redundant architecture ensures system reliability, while channel isolation and high common-mode rejection minimize signal interference in harsh industrial environments. Moreover, the AMM12C features self-diagnostic capabilities and hot-swap functionality, making maintenance straightforward without interrupting plant operations.
This module is widely used in industries such as chemical processing, oil refining, power generation, and water treatment, where accurate analog signal measurement and stability are essential for efficient automation.
