Mitsubishi A230P Digital I/O Unit Module for MELSEC-F FX Series

The Mitsubishi A230P is a combined digital input and output module designed for Mitsubishi Electric MELSEC-F (FX) series programmable logic controllers. Offering a total of 20 input and output points, the unit integrates 12 digital inputs operating at 24 V DC and 8 digital outputs operating at 24 V DC, functioning equivalently to the FX1S-20MT base configuration. This compact I/O module facilitates reliable signal acquisition and switching control in automated machinery, material handling setups, packaging systems, and manufacturing assembly lines. Engineered to interface directly with FX series automation architectures, the A230P ensures consistent DC signal transmission between field sensors, pushbuttons, actuators, and the central control processor. Built to industrial automation standards, this discontinued unit serves as a critical direct-replacement spare part to maintain legacy factory installations, minimize operational downtime, and ensure seamless continuity without requiring system re-engineering.
