SITOP SEL1400 10 A Selectivity Module, 4-channel with limiting characteristics. Input: DC 24 V/40 A, Output: DC 24 V/4x 10 A, adjustable threshold 2-10 A with monitoring interface. The SITOP SEL1400 selectivity module is the optimal addition for all 24 V power supplies to distribute and monitor the load current across multiple branches. Overloads and short circuits in one or more branches are reliably detected. The electronics allow for short-term current peaks, such as high inrush currents; branches with prolonged overload are disconnected. This is ensured even on high-resistance lines and in the case of creeping short circuits. The intact branches are supplied with 24 V without interruption or feedback, minimizing downtime of the system. Faulty branches are indicated via LEDs on the device as well as through a summary alarm contact or diagnostic monitor. Regardless of the industry or requirements, Siemens offers reliable and efficient power supplies for every system.
