The robust M200D AS-i Basic motor starter can be installed outside the control cabinet and close to the motor thanks to its compact design and high degree of protection (IP65). This is particularly advantageous for material handling and conveying where extensive distributed drive applications are the norm.
The M200D AS-i Basic is available as a direct or reversing starter for motors and can start them electronically and mechanically. The wide setting range up to 5.5 kilowatts permits flexible use of the starter. The motor starter's electronic overload relay and circuit breaker protect the motor against overload and short-circuit.Moreover, the motor starter offers optional full motor protection through the evaluation of signals from temperature sensors mounted on the motor. With the repair switch, the user can open the circuit breaker and thus interrupt the current in order to repair the motor. Diagnostic data such as the equipment status, asymmetry or overload are passed on to higher-level systems via the AS-i.
As an option, an integrated operator terminal with jog switch and maintained-contact switches for deactivating the Quick Stop function or for changing the operating mode (direct starter versus reversing starter) are available. The Quick Stop function enables rapid shutdown of the motor irrespective of bus runtimes, thus ensuring locally precise, reproducible stopping of the material being conveyed. Integrated brake controllers with voltages of 230 V/400 V AC or 180 V DC are also available.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
