- Reasons for product development
SIL 2/Cat. 3 is sufficient for approximately 95% of the machines in the area of production machines and machine tools. 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
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
- Independent execution of short-circuit test and monitoring of discrepancy time;
Versatile uses
- Mixed set-up with standard modules and SIL3/Category 4 modules
- With PROFIBUS and PROFINET via corresponding interface modules
- Distributed fail-safe expansion for the S7-300 F and S7-400F
- As a control module of the fail-safe relay module for switching voltages without external relays
- Upgrade of F functionality for existing standard systems in connection with ET 200S F-CPU and fail-safe slave-to-slave communication
