The FX2N-80MR-001: This is the 80-point relay output version of the FX2N series — 40 inputs, 40 relay outputs, running on 100-240V AC. If you're trying to keep an old line running, this is the controller you've been chasing. The I/O layout matches the FX2N-80MR-ES/UL exactly, so if that's what's in the panel, this will drop in without rewiring the terminal strip.
Cross-reference memo
The FX2N-80MR-001 and FX2N-80MR-ES/UL are electrically identical — same 40 inputs, 40 relay outputs, same 100-240V AC supply. The suffix difference is likely a regional certification variant. For a panel originally wired for the ES/UL, this is a direct swap; no rewiring needed. Both are legacy FX2N units, so if you're stocking spares, grab whichever suffix is available — the hardware is the same.
Power draw is 70VA from the 100-240V AC supply. The relay outputs handle standard solenoid and contactor loads — no derating surprises for general-purpose control. If you're swapping an older FX2N-32MR or smaller frame, remember the 80-point width takes up more DIN rail space; verify enclosure clearances before the truck heads out.
