The Siemens SIMATIC ET 200 is an I/O system for use inside and outside control cabinets. Modular design allows it to be easily scaled and expanded in small steps: digital and analog inputs/outputs, CPUs with full S7-1500 functionality, safety technology, motor starters, frequency converters, and a large variety of technology modules. These technology modules, for example, offer hardware-level signal pre-processing for rapid counting, and measurement and position registration for many different types of transducers. All of these tools and modules can be integrated in the automation system via PROFIBUS or PROFINET.
And now Siemens has introduced a new Fail-Safe Analog Input Module. Known as the ET 200SP F-AI 4xI, it enables detection of analog signals in the 0(4)..20 mA range. A special feature of the F-modules for the SIMATIC ET 200SP is the station-wide assignment of F-addresses via engineering, rather than using the DIP switch (F-address) which needs to be set for each module. When a module is replaced, however, the F-address saved in the e-coding remains in the Base Unit. And if a new module is inserted, it receives the F-address automatically. This makes the setting process much simpler.
Safety-related communication is possible via PROFIsafe. But the new fail-safe module supports the “NoDIL” concept, i.e. PROFIsafe address assignment via DIL switch is no longer required. Slots for the module can be freely selected and both central and distributed use is possible. The module is 15 mm wide. Functional safety is certified according to EN 61508. They are designed for safety-related use up to SIL 3 according to EN 62061 and PL e according to ISO 13849.
• 4 analog inputs with configurable measuring range 0..20 mA or 4..20 mA
• Supply voltage L+
• External sensor power supply possible
