Mitsubishi A68P Digital AC I/O Module for MELSEC FX Series

The Mitsubishi A68P (A68P) is a combined digital AC input and output module designed for Mitsubishi Electric MELSEC-F (FX) series programmable logic controllers. Serving as a compact mixed I/O expansion unit, this module provides automated systems with direct interfacing for alternating current control signals and electromechanical switching devices. It is functionally equivalent to the FX24MRUA1ULBB model. The module features a total of 24 digital input and output channels, arranged as 12 AC digital inputs and 12 digital relay outputs with normally open contacts. The alternating current inputs allow direct monitoring of field sensors, pushbuttons, and AC-powered control elements without external conversion hardware. Simultaneously, the 12 normally open relay contact outputs deliver reliable switching of external loads, actuators, and pilot devices across industrial machinery installations. Engineered for robust performance within MELSEC-F automation architectures, the Mitsubishi A68P enables efficient I/O density and streamlined wiring for process automation, machine control, and legacy system modernization.
