Siemens 3SK2122-2AA10 is a SIRIUS 3SK2 parameterizable safety relay basic unit for 24 V DC control systems. Siemens specifies 20 fail-safe digital inputs, four fail-safe digital outputs and two standard digital outputs in a 45 mm spring-loaded push-in terminal design. Parameterization is performed with SIRIUS Safety ES, and the unit supports safety applications up to SIL 3 and PL e when engineered within the applicable system requirements. Stockoems presents Original new condition, In stock availability and a one-year warranty as commercial terms, while coordinating suffix verification, compatibility review, protective packaging and worldwide shipping for the confirmed requirement.
Engineering must confirm the complete order number, input and output allocation, safety function, terminal system, configuration project and connected expansions. Safety performance depends on the complete validated application, not the module alone.
Condition, availability and warranty are Stockoems commercial terms, not Siemens manufacturer commitments.
Twenty fail-safe digital inputs support evaluation of connected safety devices.
Four fail-safe digital outputs provide safety-related control outputs for the engineered application.
Two standard digital outputs support non-safety status and diagnostic functions.
SIRIUS Safety ES is used to parameterize the required logic and device behavior.
Match the complete order number 3SK2122-2AA10, 24 V DC supply, push-in terminal design, Safety ES project and required fail-safe I/O allocation. Confirm connected sensors, contactors, 3SK1 output expansions, 3RQ1 coupling relays or 3RM1 fail-safe motor starters where used. Validate the complete safety function before commissioning.
It is a parameterizable SIRIUS 3SK2 safety relay basic unit for 24 V DC systems.
Siemens specifies 20 F-DI and four F-DQ, plus two standard DQ.
The official product description specifies SIRIUS Safety ES.
The unit supports applications up to SIL 3 and PL e when correctly engineered and validated.
Yes. Siemens Industry Mall lists the complete order number as Active Product.

After-sales response
We collect the complete model, suffix, quantity, destination and available nameplate or configuration-label images.
The requested order number is compared with label evidence without replacing it with a similar configuration.
Engineers assess supplied hardware, software, interfaces, licenses, mounting and application records.
Condition and available product evidence are documented as Stockoems commercial information.
Protective packaging and handling are arranged for machine-safety control equipment.
Worldwide carrier options, customs documentation and tracking are organized for the confirmed order.
Warranty scope, return authorization requirements and after-sales contacts are recorded in writing.
Exact inventory quantities and delivery timing are provided only after order-specific review.
Look for exact suffix control, clear commercial condition wording, available label evidence, written warranty terms and a documented return route.
Request product-label photos, configuration evidence, condition confirmation, packaging details, shipping documents and a named after-sales contact.
Verify the complete suffix, 24 V DC supply, fail-safe I/O allocation, push-in terminals, Safety ES project, connected devices and validated safety function.
Changed suffixes, generic photos, copied configuration data, unsupported lifecycle claims, unrealistic delivery promises and missing written terms are warning signs.
Share the complete part number, quantity, destination and product label photos for a structured procurement review.
