The PLC EduTrainer Universal/Compact from Festo Didactic is a flexible, desktop-based training system for teaching fundamental programmable logic controller (PLC) skills. It features a modular rack system—available in compact and universal sizes—with integrated power supply and safe laboratory-style connections (4 mm safety sockets and 19-inch SysLink modules). The system supports a variety of industrial-standard PLCs, including Festo’s CECC-LK (CODESYS IEC 61131‑3), Allen-Bradley CompactLogix, Siemens LOGO!, and more. Learners can build and test real-world control circuits, program in multiple languages, and extend their setup via plug-and-play input/output modules.
