The EKS is an electronic access management system for use in industrial environments. It permits secure access control to processes and software applications. It consists of an Electronic-Key, an Electronic-Key adapter and interface electronics.In the new, modular version, the electronics is accommodated apart from the Electronic-Key adapter in a separate interface adapter and can be mounted in a control cabinet, for example. Thanks to the PROFINET interface, the EKS is very simple to integrate into existing systems.The Electronic-Key adapter is characterized by a compact design and a small installation depth. It therefore can be installed in shallow control panels with standard mounting holes measuring 22.5 mm in diameter at any time. The closed and rounded shape of the Electronic-Key adapter prevents dirt deposits and permits simple cleaning. The high-molecular-weight plastic also allows use in hygienically sensitive areas such as the food industry.In the FSA version, an additional output is available as a second system channel in order to realize safety-relevant applications.
