Mitsubishi A65P Combined Digital I/O Module for MELSEC-F FX Series

The Mitsubishi A65P (A65P) is a legacy combined digital input and output expansion module developed for Mitsubishi Electric MELSEC-F (FX) series programmable logic controllers. Designed to expand system capacity in manufacturing environments, this mixed I/O unit provides a total of 48 input and output points to interface control systems with field instrumentation, switches, sensors, and actuators. The unit features 24 digital inputs rated for 24 V DC operation alongside 24 digital AC triac outputs, delivering reliable switching and signal isolation for AC loads. Functionally equivalent to the FX248MS module, the A65P integrates directly with compatible MELSEC-F series base units and extension setups to coordinate machine sequencing, process monitoring, and factory automation tasks. Although discontinued by the manufacturer, it remains widely utilized as a direct replacement component to maintain and extend the operational life of existing automated machinery without requiring controller redesign or programming overhaul.
