The Mitsubishi FX5U-64MR/ES is a CPU module in the MELSEC iQ‑F series, delivering 64 total input/output points — 24 V DC sink/source inputs and relay outputs — powered from AC supply. This is the core controller, not an expansion module; it carries the full PLC runtime and onboard I/O.
How the 64 I/O mix maps onto your panel
The 64 points are fixed: the input bank handles 24 V DC (sink/source wiring) and the output bank is relay. For a machine needing mixed-signal isolation, relay outputs simplify interfacing to 24 V AC or DC loads up to the rating. No transistor sourcing current limits to manage.
Sourcing and fit decision
To freeze a BOM line for the FX5U‑64MR/ES, the key checks are: total I/O count (64), output type (relay), and power supply (AC). No adapter or separate supply needed for the CPU. We can confirm availability and ship from the authorized channel with lot traceability.
