Together, the base units and contact expansion modules form a comprehensive safety relay system. The base units handle the logic and input processing, while the expansion modules provide the necessary output contacts to control external devices. This setup allows for flexible and reliable safety management in various industrial applications.
The base units are the core of the PNOZpower safety relay system. They are responsible for processing inputs from various safety devices, such as emergency stop buttons, safety gates, and light barriers. http://www.pilz.com The base unit evaluates these inputs based on pre-defined safety logic and makes decisions to control the output accordingly.
Base units often come with integrated monitoring and diagnostic functions. They can detect faults or errors in the safety devices or the relay system itself, providing valuable feedback for maintenance and safety compliance. They are usually configurable for different types of safety applications and can be programmed to meet specific safety requirements.
The contact expansion modules are used to extend the number of relay outputs available from the base unit. These modules are designed to handle specific load requirements and ensure that the outputs can manage the electrical loads of the connected machinery or processes safely.
Expansion modules can be added to the base unit to increase the number of outputs or to provide different types of relay contacts (e.g., normally open, normally closed). This modular approach allows for customization and scalability in safety systems. Safety solutions provider since 2011, We offer Pilz.
Each contact expansion module is specifically matched to the base unit and is designed to work seamlessly with it. This ensures that the overall system remains reliable and that safety functions are executed correctly. The modules are designed to integrate safely with the base unit to ensure that any extension of the safety system maintains the required safety integrity levels.
