What it is and where it's used

The A1SY40 is a Mitsubishi Electric i/o module from the MELSEC A / AnS, FX2N and Q-series range. Typical applications: AnS base unit output expansion, machine control. The manufacturer no longer sells this part new (discontinued 2008), which is why it is sourced from surplus stock elsewhere in Europe.

What to check before ordering

  • Original A1SY40 has a fuse and error signal to the CPU; the P version does not output that signal.
  • Complete model name including any suffix (for example -ES/UL)
  • Series and base-unit type for modular systems
  • Battery, memory cassette and extension cable requirements

If you are unsure, send us a photo of the label on the existing unit with your request and we will check it against the part number.
