Mitsubishi A64DAIC Digital I/O Module for MELSEC-F Series

The Mitsubishi A64DAIC (A64DAIC) is a discontinued combined digital input and output module designed for use with Mitsubishi Electric MELSEC-F (FX) series programmable logic controllers. Serving as a high-density expansion unit, this module provides 48 total input and output points to manage automated control signals in industrial machinery and manufacturing operations. The hardware is configured with 24 digital inputs rated for 24 V DC operation alongside 24 digital outputs featuring normally open relay contacts. Functionally equivalent to the FX248MR unit, it facilitates straightforward integration into existing automation architectures requiring reliable switching and monitoring capabilities. In industrial control environments, the A64DAIC processes field device signals from sensors, switches, and pilot devices through its 24 V DC input channels while driving external loads and indicators through its relay outputs. This combination delivers flexible discrete control for packaging lines, assembly systems, and material handling equipment running on MELSEC-F series platforms. Built for legacy control upgrades and maintenance, the module ensures dependable automation performance and continuous operation across legacy production setups.
