SITOP select diagnostic module 4-channel Input: DC 24 V/40 A Output: DC 24 V/4x 10 A Threshold adjustable 2-10 A The SITOP select diagnostic 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 continue to be supplied with 24 V with absolutely no interruption or reaction, thus minimizing system downtimes. The faulty channel is signaled via LEDs and a common signaling contact. No matter what industry, no matter what requirement - Siemens offers reliable and efficient power supplies for every system.
