More space in the control cabinet

21.04.2008
With the Sirius 3RA6 compact starter, Siemens Industry Automation (IA) has added to its portfolio a new low-voltage switchgear product for three-phase AC standard motors up to 32 amps.

The functions of overload relay, circuit breaker, and contactor are bundled in the device. This reduces installation and wiring overhead for the user and creates more space in the control cabinet. The new compact starter has its own infeed system for power supply as well as a mounting module for simple connection to AS-Interface.


At the same time, the variance of the load feeders has been significantly reduced with the Sirius 3RA6 starter. With five wide setting ranges up to 32 amps rated current, as well as three wide voltage ranges for AC/DC current with 24, 42 to 70 and 110 to 240 volts, the devices, available as direct starters or reversing starters, cover a large percentage of the application range.

With the associated Control Kit, the user performs an early check on the wiring and motor direction even before the plant starts up. This can prevent faults and increase plant availability, as can safe shutdown at the end of service life, separate indication of overload and short-circuit, and auto reset following overload trip. Removable spring-loaded and screw-type terminals also simplify device replacement for service purposes.
For efficient energy supply to the main circuit, the user can simply plug the Sirius 3RA6 compact starter into the associated, pre-wired infeed system and thus significantly reduce the wiring overhead. This infeed system can be flexibly expanded to suit the plant by adding additional slots and Sirius industrial controls components such as 3RV1 circuit breakers or the 3RV19 infeed system. As an option PE terminals are also available for this system. This provides the possibility of directly connecting the motor cables to the Sirius infeed system for 3RA6.

To further reduce the overhead involved in integration into the control circuit, Siemens offers additional, corresponding AS-i mounting modules with which the Sirius 3RA6 compact starter can be connected directly to the AS-Interface. The mounting module can easily be connected to the compact starter and used as an A/B slave for the AS-Interface. All the diagnostics and status data of the compact starter are thus forwarded direct to the higher-level controller.

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
