Is the Mitsubishi Electric A1S-68AD discontinued?

On ECS's lifecycle assessment, the A1S-68AD is discontinued and no longer supplied by Mitsubishi Electric.

Source: ECS lifecycle assessment, based on ECS's internal lifecycle data in Command Centre. Last checked . Always confirm a specific part's status with the manufacturer before buying or planning a migration.

What Total Discontinuation means for you

The manufacturer has finished with the part. You may still find one through surplus or refurbished sellers, or in another site's stores, but that is not a supply chain. Knowing where your units are, and where a spare might be, is what shortens the stoppage when one fails.

How ECS defines Total Discontinuation · all four lifecycle stages

Before replacing an analogue module

With analogue I/O, the difficult part of a migration is often hidden in the configuration: signal type, range, scaling, resolution, isolation and any filtering used by the application.

We would capture both the hardware settings and the PLC scaling logic before choosing a replacement. That gives the commissioning engineer known reference values and avoids trying to recreate process calibration from a failed module.

Know where every unit is before one fails.

A Capture audit finds every A1S-68AD on your site, photographs it where it sits and checks it against manufacturer lifecycle status, so you know your exposure and where your spares are before a failure stops a line.

  • Every device located, photographed and lifecycle-checked
  • Findings report, plus a populated Command Centre
  • No production downtime
