Electronic module for ET 200S, 8DI DC 24V, 15mm size, pieces per packaging unit. SIMATIC ET 200S is a modular, scalable, decentralized peripheral system designed specifically for installation in small machine-mounted control cabinets. The modules can be plugged directly into an ET 200S IM with CPU functionality or connected to a central controller via PROFINET or PROFIBUS. SIMATIC ET 200S can be expanded with up to 64 peripheral modules, which can be combined in any configuration. The system offers a wide range of components. Many modules are also available in different variants, significantly improving scalability in terms of functionality and price. In addition to modules with standard functionality, there are also those with extended features and diagnostics. The advantage of the ET 200S system lies in its ease of use, such as the ability to change modules and terminal boxes while the system is running. The so-called hot swapping significantly increases the availability and productivity of the machine.
