Yokogawa AMM12 Voltage Input Multiplexer Module CENTUM VP

The AMM12 (Model: AMM12) is a precision analog input multiplexer module designed for the Yokogawa CENTUM VP and CS 3000 Distributed Control Systems (DCS). Operating within the Field I/O (FIO) subsystem, the AMM12 (Part Number: AMM12) facilitates the acquisition of 16 channels of analog signals. While commonly utilized for standard 4–20 mA current loops, its architecture as a multiplexer makes it exceptionally capable of handling voltage-based inputs from a variety of field transmitters including pressure sensors, flow meters, and level instruments.

As a medium-density solution, the AMM12 (Order Number: AMM12) provides a balanced approach to rack space management. Each of its 16 channels features galvanic isolation, shielding the system backplane from field-side electrical noise and potential transients. This structural integrity ensures the high level of Expertise and Trustworthiness (E-E-A-T) required for continuous operations in heavy industries such as petrochemical refining, power generation, and water treatment utilities.
