SIMATIC ET 200S

Product profile

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

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

Typical applications

• Manufacturers of production machines and machine tools

Customer benefits

• Customers get a low-cost, digital input/output module for SIL2/Category 3 applications
• Low space requirements thanks to a combination of input and output channels in one standard F housing
• Reduction of number of types and parts based on a mixed module set-up
• More attracive pricing situation

Typical users or target groups

• Plant engineering companies
• Safety engineers

Positioning with respect to existing products/functions

• Supplements the product range as a low-cost input/output module for SIL 2/Cat.3
• Compact input/output module for applications requiring fewer fail-safe inputs and outpus

Functional dependencies on other products functions
