The SITOP PSE200U and SITOP select selectivity modules are the optimal expansion for all 24 V power supplies to distribute the load current to several feeders and to monitor it. Features and Benefits. Reliable shutdown in case of overload regardless of cable lengths or cable cross-sections. 4 load feeders per module with individually adjustable maximum current for each output. Two versions for remote diagnostics: Group signaling contact or single-channel signaling. Evaluation via free-of-charge SIMATIC S7 function blocks (S7-1500/1200/300/400) for modules with single-channel signaling (PSE200U). LEDs for rapid on-site fault localization. Remote reset possible from a central location (PSE200U). Simple commissioning thanks to manual switch on/off of outputs (PSE200U). Sequential connection of feeders to reduce total inrush current. Sealable transparent cover over adjusters for currents and times protects against maladjustment (PSE200U). Advantages of a selectivity module. A power supply unit (PSU) cannot guarantee a fault-free supply when used on its own. The selectivity module offers reliable detection of overload or short-circuit in the circuit. A selectivity module enables reliable shutdown in case of overload regardless of cable lengths or cross-sections.
