Siemens SITOP PSE200U Selectivity Module DIN Rail Power Supply 22 → 30V dc Input, 24V dc Output, 10A

SITOP PSE200U Selectivity Module

The SITOP PSE200U selectivity module is the optimal addition to all 24 V power supplies for distributing and monitoring the load current across several branch circuits. Overload and short-circuit in one or more feeders are reliably detected.
The electronics tolerate short-term current peaks, e.g. due to high inrush current, and de-energize feeders with longer overload. This is ensured even on high-resistance cables and for short-circuits that develop slowly over time.
The intact feeders continue to be supplied with 24 V without any interruption or disturbance, thereby minimizing plant downtimes. The faulty feeder is signalled using LEDs and a group signal contact. Regardless of the industry or requirements, Siemens offers reliable and efficient power supplies for every plant.

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 signalling


• 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.
