The Mitsubishi FX5U-64MR/DS is a CPU module from the iQ-F series, carrying 64 mixed I/O points — 32 inputs rated for 24 V DC sink and 32 relay outputs. The relay output side is the key distinction here: it handles general-purpose AC/DC loads up to the contact rating, but it’s not a transistor module. If your line or legacy design expects sourcing (PNP) outputs or fast switching, this part swaps in only after a wiring review. The terminal block is screw-type, so an existing panel wired for a connector-based CPU (like the FX5UC series) will need re-termination at the board.

Frequently asked questions
What are the input and output types?
Inputs are 24 V DC sink; outputs are relay, with 32 points each.
Can I replace an FX5UC-64MT/D with this module without rewiring?
No. The FX5UC-64MT/D uses transistor outputs and a connector; the FX5U-64MR/DS uses relay outputs and screw terminals. The panel must be rewired.
