Mitsubishi FXON-3A Analog I/O Module for MELSEC FX Series

The Mitsubishi FXON-3A (FXON-3A) is a compact mixed analog input and output module designed for Mitsubishi Electric MELSEC-F (FX) series programmable logic controllers. Engineered to expand the analog capabilities of compact automation systems, this expansion unit provides combined analog signal acquisition and signal generation within a single hardware block. The unit features a total of three analog channels, comprising two analog inputs and one analog output. Both the input and output circuits support configurable standard electrical signal ranges, including 0 to 10 V DC, 0 to 5 V DC, and 4 to 20 mA current loops. The module performs 8-bit resolution analog-to-digital and digital-to-analog conversion, enabling reliable interfacing with process instrumentation, measurement sensors, variable frequency drives, actuators, and control valves. By integrating both input and output functions, the module minimizes hardware footprint in small-scale automation setups. The unit integrates seamlessly with the FX series architecture to deliver cost-effective analog control for industrial processing, fluid handling, and automated machinery.
