Student experiments for contact control with modules on the mounting wall


  • Basic control elements with contactor
  • Basic control circuits with contactor
  • Basic control circuits for machines

The learning system consists of handy, robust experimentation modules that can be freely and clearly arranged on a mounting wall in accordance with the circuit diagram. The modules are coloured in order to allow for better organisation.

A transparent back wall enables participants to observe the industry standard equipment used, in the case that it is not mounted on the front. The module snaps into the mounting wall by way of an elastic catch, so that it won’t fall out when plugged into the connecting lines.

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


Student experiments based on the assignments in the experiment description.
