Mitsubishi FX3-4AD Analog Input Module for MELSEC FX Series

The Mitsubishi FX3-4AD (FX3-4AD) is an analog input special function block designed for use with MELSEC-F and FX series programmable logic controllers. This expansion module enables the PLC to interface with external analog field devices by receiving and processing up to four independent analog input signals, converting them into precise digital values for control, data acquisition, and process monitoring. The unit features four input channels that accommodate both voltage and current signals, offering flexible configuration for industrial instrumentation. For voltage signals, the module operates across an input range of -10 V to +10 V DC, while current inputs support standard 4 mA to 20 mA DC loops. Integrated into automation architectures, the module delivers dependable analog data conversion for monitoring parameters such as pressure, temperature, flow rates, and position across manufacturing, processing, and assembly machinery. The Mitsubishi FX3-4AD provides seamless integration with compatible MELSEC-F controller racks, facilitating reliable signal processing and accurate feedback for complex industrial control systems.
