Spare-part module for the S7-200 analog front-end
The 6AG1231-0HC22-2XB0 is a Siemens SIPLUS S7-200 EM231 analog input module, a spare part carrying the form, fit, and function of the standard 6ES7231-0HC22-0XA0 but rated for an extended operating temperature range of -25 to +70°C.
Cross-reference note – not interchangeable with LOGO! modules
The listed peer modules 6ED1052-1FB00-0BA1, 6ED1053-1BB00-0BA2 and 6ED1053-1FG00-0BA0 belong to the Siemens LOGO! family and are not form-fit-function equivalents — they connect to a different backplane protocol and cannot drop into a panel wired for the S7-200 EM231 without re-engineering.
Sourcing and procurement
Because this is a catalogued spare part with current lifecycle status, sourcing is handled through standard Siemens distribution channels. We procure to order against an RFQ — no minimum order line, but lead times depend on batch sizing.
