Typically, these modules are designed to be easily added to an existing setup. They often connect via a standardized interface or bus system, ensuring seamless integration with the base unit. Allows you to scale the number of safety contacts according to your needs without extensive system overhauls.
By adding expansion modules, you can increase the number of available contacts without needing to replace the entire base unit. This is especially useful in applications where the number of required safety contacts exceeds the base unit’s built-in capacity. http://www.pilz.com Safety solutions provider since 2011, We offer Pilz.
