      Information

      Overview Manuals Common Applications Product Precautions
      The Siemens 6EP1961-2BA21 is a SITOP PSE200U selectivity module with four independently monitored 24 V DC load circuits. It detects overloads or short circuits and disconnects affected branches so healthy control loads can remain supplied.
      • 24 V DC, up to 40 A
      • 4 x 24 V DC / 10 A
      • 3 to 10 A per channel
      • Common signaling contact

      Installed downstream of a suitable SITOP power supply, it segments PLC, HMI, sensor, actuator, and communications loads and provides a common signaling contact for diagnostic integration.

      Important Notice: Use the complete 6EP1961-2BA21 code and verify the physical nameplate and current Siemens documentation before installation or replacement.
