Mitsubishi Electric FX2N-4AD Analog Input Module

The Mitsubishi Electric FX2N-4AD is a four-channel analog input module for the MELSEC FX2N PLC family, described as a special function analog block. It provides four input channels designed to acquire analog signals in a 24VDC environment and convert them into digital values for the PLC to process. This module is used to read signals from sensors and transducers in automation and process-control applications, enabling monitoring of variables such as temperature, pressure, level, or flow when connected to appropriate transducers. As part of the FX2N series, the FX2N-4AD pairs with a compatible FX2N CPU and other MELSEC I/O blocks to extend the PLC's analog sensing capability in a compact, modular I/O chassis. The presence of four channels supports multi-point sensing without multiple separate modules, which can simplify wiring and reduce panel footprint. This description reflects the device's primary function and its construction as a 24VDC analog input block, suitable for integration into standard MELSEC automation configurations.
