One letter, different wiring.

The letters after the I/O count set the output type. We match every one before we quote.

  • Relay or transistor

    FX3U-32MR/ESvsFX3U-32MT/ES

    The same base unit. One has relay outputs, the other transistor outputs.

  • Sink or source

    FX3U-32MT/ESvsFX3U-32MT/ESS

    Both have transistor outputs. One is sink, the other source. Fitting the wrong one means rewiring.
