Mitsubishi Electric JY331A81301D Programmable Logic Controller Module

The Mitsubishi Electric JY331A81301D FX2-CPU circuit board is the CPU module for Mitsubishi's FX2-series programmable logic controllers, identified by part number JY331A81301D. This FX2-CPU board acts as the brains of the FX2 automation system, running the user programs and managing the flow of data between the PLC's inputs, outputs, and connected peripherals. In FX2 configurations, this circuit board is designed to be inserted into a compatible chassis alongside I/O modules and other system components, providing execution, timing, and control sequencing essential to machine automation tasks. Because the part is a dedicated CPU module, it is typically used as a direct replacement or upgrade where the FX2-controller needs a reliable, Mitsubishi-branded CPU core to maintain program integrity and system performance across industrial environments. The JY331A81301D designation helps ensure correct identification during sourcing and maintenance within repair workflows and inventory management.
