Siemens 6EP4438-7EC00-3DX0SITOP SEL1400 selectivity module

SITOP SEL1400 EX 10 A Selectivity Module, 8-channel with limiting characteristics. Input: DC 24 V/60 A, Output: DC 24 V/8x 10 A, adjustable threshold 2 - 10 A with monitoring interface. The SITOP SEL1400 selectivity module is the optimal complement for all 24 V power supplies, allowing the load current to be distributed and monitored across multiple power 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, while 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 completely interruption-free and without feedback, thereby minimizing downtime of the system. Faulty branches are signaled 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.
