SITOP SEL1400 10 A selectivity module 4-channel with limiting characteristics Input: DC 24 V/40 A Output: DC 24 V/4x 10 A Threshold adjustable 2-10 A with monitoring interface The SITOP SEL1400 selectivity module is the ideal addition to all 24 V power supplies to divide the load current between several current branches and monitor it. Overload and short circuits in one or more branches are reliably detected. The electronics allow short-term current peaks, e.g. due to high inrush current, and switches branches with longer overloads off. This is ensured even on high-impedance lines and in the event of creeping short circuits. The intact branches are supplied with 24 V with absolutely no interruption or reaction, thus minimizing system downtimes. The faulty branch is signaled via LEDs on the device and via a common signaling contact or diagnostic monitor. No matter what industry, no matter what requirement - Siemens offers reliable and efficient power supplies for every system.
