Modular electrical device used in industrial automation control system, has backplane formed by mutually interlocked base components with base connectors for receiving removable modules

摘要

The backplane contains multiple interlocked base components (12c2), arranged to form multiple module mounting locations (M2), so that each module contains two electrical base connectors from different base components for receiving removable modules and providing electrical connections. A coupling arrangement with a lock (74) is provided in the lock plane for fixing the modules.
