It scales to 128 I/O with expansion modules, so you can match the card count to the line instead of swapping the whole CPU. ## Transistor sink outputs — what that buys you 8 transistor (sink) outputs switch the load to ground. No mechanical contacts to wear. The FX5-8EX/ES is an input-only expansion module for the MELSEC iQ-F series, not a main unit. It adds 8 DC inputs (sink/source) but needs an FX5 CPU to talk to. The FX3U-16MT/DS is a self-contained controller — you can't swap one for the other without changing the backplane and the programming environment. If your BOM says FX3U-16MT/DS, the FX5-8EX/ES isn't a second source; it's a different animal.","metaTitle":"Mitsubishi FX3U-16MT/DS PLC Main Unit, 8 DIO, Transistor Sin","metaDescription":"Mitsubishi FX3U-16MT/DS main unit, 24VDC, 8 inputs / 8 transistor sink outputs, 25W, mature lifecycle.
