This model is part of the SITOP Redundancy Module family and is designed specifically to decouple two SITOP power supplies, enabling independent operation of each supply with a shared load up to 40 A total. The module's input\/output specification is 24 V DC \/ 40 A, and it provides SELV protection per EN 60950-1 with a relay contact for signaling. It is intended for use with SITOP PSE202U configurations, providing reliable 24 V DC power for industrial automation hardware such as PLCs, sensors, and actuators that require dual-power-source redundancy. The 6EP1961-3BA21 designation uniquely identifies this redundancy module among Siemens' SITOP accessories, ensuring compatibility with SITOP power supply setups that use the PSE202U redundancy scheme.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"New","offer_id":46268484813034,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-018.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/siemens-6ep1961-3ba21-redundancy-power-supply-module","provider":"GTG Hardware","version":"1.0","type":"link"}
