SITOP PSE200U 3 A NEC CLASS 2 selectivity module 4-channel Input: DC 24 V/12 A Output: 24 V/4x 3A NEC class 2 Threshold adjustable 0.5-3 A with status message for each output 'The SITOP PSE200U selectivity module is the optimal addition to all 24 V power supplies to divide the load current between several current branches and to monitor it. Overload and short circuit 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 case of creeping short circuits. The intact branches continue to be supplied with 24 V without interruption or feedback, thus minimizing system downtimes. The faulty channel is signaled via LEDs and individual channel messages. Free function blocks for SIMATIC S7, STEP 7 and TIA Portal as well as SIMOTION CPUs with SIMOTION SCOUT are available for their evaluation. The outputs meet the requirements of NEC Class 2. No matter what industry, no matter what requirement - Siemens offers reliable and efficient power supplies for every system.'
