Product details

I/O capacity and memory ceiling

The FX2N-128MT-ES/UL provides 184 input points (X000–X267) and 184 output points (Y000–Y267), both in octal numbering, with expansion support for additional I/O when used with extension blocks. Program memory holds up to 16000 steps including comments and file registers, which sets the practical application size limit for this controller.

Power supply and grounding

Rated for AC100–240V at 50/60Hz, with a 5A 250V power fuse. Inrush current reaches 40A max at AC100V and 60A max at AC200V for up to 5ms. Requires Class D grounding (ground resistance 100Ω or less) and must not share a common ground with high-voltage systems — dedicated or shared grounding is specified.

Environmental and mechanical ratings

Withstands vibration per IEC61131-2: 57–150Hz at 9.8m/s² in X, Y, Z directions for 80 minutes each, and shock of 147m/s² for 11ms half-sine pulse. Operating atmosphere must be free of corrosive gases, flammable gas, and conductive dust; altitude limited to 2000m or less, and not for pressurised environments above atmospheric pressure.

Available through independent surplus and broker channels. Quantities are lot-specific; availability and pricing are confirmed at RFQ against the BOM line.
