The 3SK2122-1AA10 Siemens SIRIUS safety relay Basic unit may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
Siemens 3SK2122-1AA10 SIRIUS safety relay Basic unit datasheet(Datasheets), Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
The 3SK2122-1AA10 employs a dual-channel redundant monitoring mechanism. It continuously scans input signal levels and pulse test signals via its internal microprocessor to detect short circuits, open circuits, or synchronization errors in the circuit. Once a trigger signal (e.g., pressing an emergency stop button) is detected at the input or a logic judgment fails to meet safety conditions, the processor will shut down the safety output with a millisecond-level response time, forcing the device into a safe stop state by cutting off the power to the actuator (e.g., a contactor or frequency converter).
Current Status: This product is currently available in the Siemens product portfolio. Modular Expansion: Seamless expansion is possible via device connectors using the SIRIUS 3SK1 output expansion module and 3RQ1 coupling relay, significantly reducing manual wiring.
