The '14' in the order code is the I/O count, not a model index, so a panel specified for 14 points lands directly on this part without leaving a block half-empty. Inputs are 24 VDC sink/source and outputs are relay, which is the standard mixed-IO pattern on a small-format Mitsubishi base unit. Supply is 100-240 VAC, so the unit takes a single AC feed from the panel and exposes 24 VDC to the field inputs from its own terminal block. The base unit measures 90 mm tall by 60 mm wide by 75 mm deep, which is the DIN-rail footprint to budget before the BOM freezes and the panel layout is drawn. ## Cross-shop note against the FX1N-24MR-ES/UL The FX1N-24MR-ES/UL sits one generation back at 14 inputs and 10 outputs (24 I/O total) on the same 100-240 VAC supply and the same relay output convention. The I/O count differs by 10 points and the platform generation is older, so the FX1N-24MR-ES/UL is not a same-frame drop-in for a panel designed around the FX3S-14MR/ES — the wiring map and the program portability both need to be re-checked before any swap is signed off.","metaTitle":"Mitsubishi FX3S-14MR/ES PLC, 14 I/O, Relay","metaDescription":"Mitsubishi FX3S-14MR/ES CPU base unit, 8 inputs / 6 relay outputs, 24 VDC sink/source, 100-240 VAC supply, lifecycle current.
