The Siemens 6AG1057-1AA01-0AA0 is a programming device for LOGO! modules, running on a 100 to 230 V AC supply. Out here in the grease, we see these little programmers still pulling duty in panels where a LOGO! has to be reconfigured without a laptop. If your BOM calls it out for programming a LOGO! module, this is the exact piece.
Lifecycle & Sourcing
Listed as current in the lifecycle stage, so it's not an EOL part you have to hunt through surplus channels for. This line is still live and orderable. For commitment to a BOM, we can quote it to order against an RFQ — no last-time-buy pressure yet.
