The 6AG1223-1BL22-2XB0 is a SIPLUS variant of the S7-200 EM223 digital I/O expansion module, explicitly labeled as a spare part for the standard 6ES7223-1BL22-0XA0. It extends the operating temperature range to -25...+70°C, compared to the standard module's 0...+55°C, making it the choice for environments like outdoor cabinets, cold stores, or foundry floors where the ambient strays outside the commercial envelope. The module snaps onto the S7-200 DIN-rail bus and draws its power from the backplane — no separate supply wiring needed.
Lifecycle status — still current, not end-of-life
Because this is a SIPLUS spare part, it does not carry a standard catalog successor; the replacement path is simply the same 6AG1223-1BL22-2XB0 order code.
