Mitsubishi FX5-4AD 4-Channel Analog Input Module for MELSEC-F FX Series

The Mitsubishi FX5-4AD (FX5-4AD) is a four-channel analog input expansion module engineered for the MELSEC-F FX series programmable logic controller family, including FX5 systems. This module provides analog-to-digital conversion, allowing host controllers to accurately interface with sensors, transducers, and measurement devices across industrial automated processes. The unit features four independent analog inputs supporting both voltage and current signals. Supported voltage input ranges include 0 to 10 V DC, 0 to 5 V DC, 1 to 5 V DC, and -10 to +10 V DC. Supported current input ranges include 0 to 20 mA, 4 to 20 mA, and -20 to +20 mA. With a high conversion resolution of 1/16000, the module delivers precise signal processing for demanding monitoring and closed-loop control tasks. It serves as an equivalent replacement for part number FX54AD. Typical applications include process parameter monitoring, temperature and pressure regulation, level measurement, flow rate logging, and automated manufacturing equipment where precise analog data acquisition is critical.
