Press Release Summary:
Complimenting all 24 V power supplies, Sitop PSE200U distributes and monitors load current across several load feeders. Overloading and short circuits are displayed on separate LED for disconnected channel. Channel-specific signalling - indication of faulty 24 V load circuit - is available in selectivity modules with outputs of either 4 x 3 A or 4 x 10 A. To enable channel-specific analysis, message output is connected to controller's digital input.
Original Press Release:
Selectivity Module with Channel-Specific Signalling for all 24 Volt Load Circuits
Nuremberg, Germany. Channel-specific diagnosis has now become possible with the new version of the Sitop PSE200U selectivity module. This new unit from the Siemens Industry Automation Division perfectly complements all 24 volt power supplies by distributing and monitoring the load current across several load feeders.
Overloading and short circuits are displayed on a separate LED for the disconnected channel. Channel-specific signalling, i.e. indication of the faulty 24 volt load circuit, is available in Sitop selectivity modules with outputs of either 4 x 3 or 4 x 10 amperes.
In the past, only a collective message used to be sent to indicate that one or more out of the four channels was disconnected. The new module signals exactly which channel was faulty and has therefore been disconnected.To enable channel-specific analysis, the message output is connected to a standard digital input of the controller.
A pulse-pause log allows indication of the disconnected channel and its rapid analysis via the controller. A Simatic S7 functional module for simple integration into the controller is available free of charge in the Internet.
The Sitop PSE200U selectivity module distributes the load current across several 24 volt DC load circuits and monitors them reliably for overloading and shortcircuits.
The electronics permit brief current peaks caused, for example, by high in-rush currents. The module switches longer overloads off-circuit. Overloading and short circuits in a load circuit are reliably identified and displayed via LED.
