SITOP SEL1200 10 A selectivity module 4-channel with switching characteristics Input: DC 24 V/40 A Output: DC 24 V/4x 10 A Threshold adjustable 2-10 A with monitoring interface The SITOP SEL1200 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, 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.
