Fail-safe distributed I/O modules for use up to Ex Zone 1/21

24.11.2010
The Siemens Industry Automation Division has developed three fail-safe modules for the Simatic ET 200iSP intrinsically safe distributed I/O system.

The new modules 8F-DI Ex Namur, 4F-DO Ex 40mA/17.4V and 4F-AI Ex Hart meet the high safety requirements in accordance with the relevant standards such as IEC 61508 to SIL 3. This means that, integrated into the Simatic ET 200iSP distributed I/O system, they can be used direct without Ex barrier up to Ex Zone 1/21.


The connected intrinsically safe sensors and actuators can be run into Ex Zone 0/20. The new modules are suitable for applications such as ESD (emergency shut down), boiler protection, or fire and gas equipment. For fire and gas applications, the new modules have the important diagnostics functions "Last valid value" and "Energize-to-trip".

The intrinsically safe Profibus version is used for communication between the Simatic ET 200iSP distributed I/O system and the higher-level controllers. The same cable is used here for transferring the standard automation data and the fail-safe signals in accordance with the Profisafe profile. The Simatic ET 200iSP is configured with the Step 7 engineering tool. Off-the-shelf, TÜV-certified library blocks are available in the Step 7 option packages Distributed Safety and S7 F-Systems for fail-safe applications.

Im Focus: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
