Student experiments for contact control with plate system on a frame.
Objectives:
- Basic control elements with contactor
- Basic control circuits with contactor
- Basic control circuits for machines
The experiment plate system is comprised of handy, robust experiment plates that are arranged on a frame in accordance with the specifications in the literature.
The industry standard equipment is affixed to the front. The operation and notification elements are installed on separate plates.
The electric components are wired directly to the corresponding safety connector using a 4 mm safety connection line for low voltage.
The control voltage amounts to 24 V DC.
Learning methods:
Student experiments based on the assignments in the experiment description.
- Arrangement of the elements
- Wiring
- Function review
Vocational training in electric engineering for handwork and industry
Intermediate, prerequisites fundamentals of contactor controlling and instruction in the dangers associated with electrical engineering.
The system could be supplemented by the system machines.
