The SITOP PSE200U, SITOP select and SITOP SEL1200/-1400 selectivity modules are the optimal expansion for all 24 V power supplies in order to distribute and monitor the load current across multiple feeders. Overload and short-circuit in one or more feeders is reliably detected and signaled.
The electronics permit brief current peaks caused, for example, by high inrush currents, but disconnects feeders in the event of an extended overload. This is ensured even on high-resistance lines and in the case of “creeping” short-circuits. In such cases, miniature circuit breakers fail to trip, or trip too late, even if the power supply unit could deliver the required tripping current. The SITOP expansion module continues to supply the intact feeders with 24 V absolutely free of interruptions and feedback – a feature which avoids a possible total system failure.
The selectivity module is used in conjunction with 24 V power supplies to distribute the load current over several feeders and to monitor the individual currents. Faults in individual circuits caused by overload or short-circuit are detected and selectively switched off so that further load current paths remain unaffected by the fault. This achieves fast fault diagnostics and minimizes downtimes.
The selectivity module is specially designed for the response of switched-mode power supply units and the 24 V DC feeders to be supplied. Individual setting of the response threshold allows optimum adaptation to the respective feeder.
Monitoring
The current per output is monitored by the selectivity modules; if the set threshold of the output is
exceeded, the output is
switched off according to a predefined time-current characteristic curve. In addition, the supplying 24 V input voltage is constantly being monitored. As soon as this voltage threatens to fail, the path with a higher current than the set threshold is
disconnected immediately. All other feeders continue to be supplied without interruption.
Signaling
Signaling of the faulty feeder takes place by the LEDs on the device as well as via group signaling contact or single-channel signaling. The selectivity module with its single-channel signaling option outputs the status of the individual outputs cyclically, by means of a serial code which can be read in by a digital PLC input.
Free function blocks for SIMATIC S7-300/400/1200/1500 for STEP 7 and TIA Portal as well as SIMOTION CPUs with SIMOTION SCOUT are available for evaluation. This enables simple integration into the S7 diagnostics and host control or HMI systems. The integration into the LOGO! logic module is also an application example.

Connecting and disconnecting the outputs
During device startup you can select between simultaneous connection of all outputs, as well as sequential connection or load-dependent connection in order to reduce the peak inrush currents.
Each output can be manually connected and disconnected on the device (for example, for commissioning or service). Disconnected outputs can be connected by means of remote reset (24 V input). Prerequisite is that the outputs were not disconnected manually on the device.
Switch-off characteristic
The SITOP PSE200U, SITOP select and SITOP SEL1400 redundancy modules feature a limiting switch-off characteristic, whereas the SITOP SEL1200 redundancy modules have a switching one. The SITOP SEL1200 is adequate for all load components which correspond to the PLC standard. With this module, the voltage can briefly drop below 20 V. The SITOP SEL1400 prevents voltage drops below 20 V in the loads and therefore also protects those components which do not correspond to the PLC standard.
