EEE lab & training benches
A teaching bench should use the same class of PLC, motor, sensor and protection you will see in a real panel — just smaller, safer and documented.
The problem
Student projects and department labs often mix toy sensors with industrial contactors, or buy a PLC with no 24 V rail, no overload, and no way to show a VFD running a real motor. The experiment becomes a wiring accident. Instructors need a kit that demonstrates DOL vs VFD, NPN vs PNP, and a short ladder sequence without requiring a factory budget.
How this desk works it
We kit benches around a compact PLC, 24 V SMPS, a small three-phase or well-protected motor, optional VFD, M18 sensors, contactor + overload, and HMI if the course needs an operator screen. Specs are written as learning outcomes: “student can size an overload from FLA”, not as marketing. Same supply desk as the factory catalog — so a graduate can reorder the industrial version later.
What you walk away with
A lab-safe parts list with clear voltages, a suggested I/O map, and commercial parts that survive more than one semester.
Working method
01
Define the experiment
DOL starter, VFD speed pot, sensor counting, or a mini conveyor. One clear outcome per bench.
02
Lock the voltages
24 VDC control recommended for student I/O. Power side stays behind protection and supervision.
