Mitsubishi FX3-4DA Analog Input Module for MELSEC-F Series

The Mitsubishi FX3-4DA (FX3-4DA) is a special function block designed for analog signal input in Mitsubishi MELSEC-F series programmable logic controllers. Engineered to interface directly with the PLC main unit, this module enables advanced data acquisition and measurement in automated machinery. It converts four analog input signals, supporting voltage and current inputs, into corresponding digital values that are transferred to the primary PLC processor for program execution and data handling. Through this multi-channel conversion, the module allows control systems to accurately monitor diverse industrial variables including temperature, pressure, and level. These digitized values are utilized directly within the user PLC program for system control, feedback regulation, and data acquisition tasks. Widely applied across diverse manufacturing environments utilizing MELSEC-F series hardware, the unit provides reliable analog signal conditioning, continuous variable tracking, and stable communication with the central PLC controller.
