Introduction
The Yokogawa AMM42 is an analog multiplexer input module designed for distributed control systems where multiple analog signals must be collected, conditioned, and forwarded to a central controller. It is frequently used in process automation environments that rely on numerous 2-wire transmitters, such as flow, temperature, level, or pressure instruments.
Its compact form factor and stable signal-handling performance make it suitable for dense I/O installations where panel space and wiring efficiency are critical.
