Is the Siemens 6ES7522-1BL00-0AB0 discontinued?

On ECS's lifecycle assessment, the 6ES7522-1BL00-0AB0 is discontinued and no longer supplied by Siemens.

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 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.
