SIMATIC ET 200S- EM 4 F-DI / 3 F-DO DC24V/2A

Siemens Ltd. - The EM 4 F-DI / 3 F-DO DC24V/2A is a cost-optimized and space-saving fail-safe SIMATIC ET 200S module with 4 inputs and 3 outputs which can be used for safety requirements up to SIL 2 and/or Category 3. The optimized input/output module for all SIL2/Category 3 applications

Reasons for product development
In the area of production machines and machine tools, SIL 2/Cat. 3 is sufficient for approximately 95% of the machines. With digital, fail-safe inputs and outputs for the ET 200S exclusively tailored to the requirements of SIL 2/Cat.3, it is possible to cut costs drastically with a bus-based, fail-safe solution compared to present solutions. Therefore, even if only a few F channels are required, this technology adds functional value at a more attractive price.

Functional highlights and outstanding technical features of SIMATIC ET 200S- EM 4 F-DI / 3 F-DO DC24V/2A:
* High functionality for compact spaces
- 3 current-sinking/sourcing outputs; aggregate current of outputs: max. 4A
- 4 input channels (2-out-of-2 evaluation), supply voltage L+: 24 V
* Integrated diagnostic functions
