Overview
The FX2N-128MR-ES/UL is a Mitsubishi FX2N series programmable controller with 64 inputs and 64 relay outputs, supporting a maximum of 128 I/O points for medium-scale machine control. It runs on a 100-240V AC supply and draws 100VA, with relay outputs that handle mixed AC/DC loads without external interposing relays for most applications.
How it compares
Compared to the FX2N-64MR-ES/UL, the FX2N-128MR-ES/UL doubles both input and output counts (64 vs 32 each) and raises max I/O from 64 to 128, while power consumption increases from 60VA to 100VA — the same supply voltage and relay output type are shared, so panel wiring and power distribution remain consistent when scaling up.
