SIMATIC ET 200SP, Base Unit BU15-P16+A0+2B/T, BU Type A1, Push-In terminals, without AUX terminals, bridged to the left, dimensions: 15x 117 mm, with temperature detection. SIMATIC ET 200SP is a modular, scalable, and highly flexible decentralized peripheral system. Its small footprint makes it particularly suitable for installation in compact machine-mounted control cabinets. The modules can be directly plugged into an ET 200SP CPU or connected to a central controller via PROFINET or PROFIBUS. SIMATIC ET 200SP can be expanded with up to 64 peripheral modules, which can be combined in any configuration. The system offers a very extensive range of components. Many modules are also available in different versions, significantly enhancing scalability in terms of functionality and price. In addition to modules with standard functionality (ST), there are also those with extended functionality and diagnostics (HF High Feature / HS High Speed). For price-sensitive applications, modules with basic functionality (BA) are available. The advantage of the ET 200SP system lies in its ease of use, such as the free choice of PROFINET connection technology via the bus adapter, tool-free wiring through Push-In technology, improved accessibility of wiring due to the new arrangement of the spring openers next to the corresponding conductor opening, and channel-specific diagnostic functions. The ability to perform module and terminal box changes during operation, known as hot-swapping, ensures the availability and productivity of the machine. The scalable and cost-optimized configuration of an ET 200SP station is supported by the comprehensive range of signal modules. In addition to digital and analog input and output modules, fail-safe variants for applications up to SIL 3 / PLe are also available.
