ECS stage: Cancellation.

Is the Rockwell 1746-OB16 discontinued?

On ECS's lifecycle assessment, the 1746-OB16 has been cancelled: no longer sold as a current product, though spares may remain available for a period.

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 Cancellation means for you

You can no longer order it as a normal product, and nothing new should be designed around it. If machines depend on it, you want spare stock you can rely on and a migration plan. Both start with knowing how many you run.

How ECS defines Cancellation · all four lifecycle stages

Before replacing an output module

Output modules need a load-by-load check rather than a simple channel-count comparison. We would confirm whether each point is switching relays, solenoids or other loads, the current requirements, common arrangements and any interposing devices.

Those details determine whether a proposed replacement behaves electrically like the original and whether PLC logic or wiring must change. A documented output schedule is particularly valuable if the original module fails before a migration is planned.

Know where every unit is before one fails.

A Capture audit finds every 1746-OB16 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
