Mitsubishi FX5U-64MT/ES CPU module with 32 input points (24 V DC sink/source) and 32 transistor sink outputs, powered by 100–240 V AC. Sink output connects the load between the output point and the DC common. This matters when swapping into a panel wired for source outputs — the wiring polarity reverses.
Sink vs source — the one difference that rewires your panel
The closest functional twin is the FX5U-64MT/ESS. Both have 32 inputs and 32 outputs, same power supply, same frame. The /ESS uses transistor source outputs instead of sink. If your panel uses source outputs, the /ES will require re-terminating output commons and verifying diode clamping.
