Selectivity module Siemens

Область применения



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.

Selectivity and rapid fault localization in 24 V feeders

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. 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.

Дизайн



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 current allows optimum adaptation to the respective feeder.

Функции



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 single-channel signaling outputs the status of the 4 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.

Connection and disconnection of the outputs
During device startup you can select between simultaneous connection of all outputs as well as sequential connection or load-dependent connection of the outputs (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.

Особенности


  • 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)
