Safety Didactic Cube

SHORT SUMMARY

The Safety Didactic Cube (SDC) is an educational testbed that helps demonstrate how industrial safety systems behave in a controlled, hands-on environment. It allows students, trainees, and professionals to see how safety components react when something goes wrong, so they can understand how accidents are prevented and how safe operation is maintained. The platform includes common industrial safety devices such as safety relays, safety controllers, light curtains, safety switches, and emergency stop functions. Through interactive scenarios, users can observe in real time how the system responds to different inputs, such as stopping machine operation, switching to a safe state, or activating interlocks when unsafe conditions are detected. A key focus is placed on understanding safety logic, emergency shutdown behavior, access control, and how systems are safely restarted once normal conditions are restored. By connecting theory with real system responses, the SDC helps users build practical knowledge of functional safety and develop the skills needed to design, operate, and manage industrial systems safely.

APPLICATION CASES

APPLICATION CASES

Application case:	Short description:
Demonstration of industrial safety components	The Safety Didactic Cube is used to demonstrate the operation of key industrial safety components such as safety relays, safety controllers, light curtains, laser scanners, and safety switches. It provides a hands-on learning environment for understanding safety principles.
Safety logic and control validation	Students and industrial trainees can test different safety logic configurations using safety controllers and relays, understanding how safe states are achieved in industrial systems.
Emergency stop and LOTO	Practical training scenario where users activate the E-STOP and observe system behavior, including immediate shutdown and safe restart procedures in accordance with safety standards. Additionally, users are trained in Lockout/Tagout (LOTO) procedures, including proper energy isolation, application of locks and tags, and verification of zero-energy states before maintenance or intervention.
Guard monitoring and access control simulation	Demonstration of how safety switches and interlock devices monitor protective doors and prevent unsafe machine operation when guards are open.
Safety curtains training	Training on light curtains and safety laser scanners, showing how intrusion detection works and how safety zones are monitored in real time without physical contact.
