Yokogawa AAM10 Current/Voltage Input Module

Module Purpose and Functionality:

This input module is engineered to interface with both 2-wire transmitters that deliver 4-20 mA current signals and 1-5 V voltage signals. It offers flexibility by processing a broad spectrum of input signals, extending its capability to handle signals that fall outside of the standard range.

Integration with Transmitters:

The module is also compatible with transmitters that feature BRAIN Communication functionality. This integration allows seamless communication between the Information and Command Station (ICS) and the connected transmitter, enabling effective data exchange and control.
