Siemens 6EP1961-2BA61 Selectivity Module is part of the SITOP PSE200U family and provides four NEC Class 2 24 VDC output channels with individual status signaling. The unit accepts a 24 V DC input capable of up to 12 A and distributes 24 V across four outputs rated at 3 A each (total 12 A). Each channel incorporates an adjustable switching threshold from 0.5 A to 3 A and reports a status indication per output, enabling selective fault isolation in 24 V DC power architectures. Used with Siemens SITOP power supplies in automation and control panels, it helps manage load selection and fault signaling while maintaining NEC Class 2 compliance.
