Flexi Classic Modular Safety Controllers

SICK Flexi Classic series modular safety controllers offer an easy-to-use solution for machine safety without the need for programming software. Logic functions are configured directly on the modules using rotary switches, making setup fast and intuitive. Modules communicate through an internal bus system, providing diagnostic information for efficient troubleshooting. The product family includes gateways for connecting to higher-level non-safe controls without affecting safety logic, as well as muting modules for advanced applications. For added convenience, the Flexi Classic configurator tool generates wiring diagrams to simplify installation. This modular approach ensures flexibility, quick commissioning, and reliable safety for a wide range of industrial environments.
