Proposed is a training and simulation device for electric functional processes in electric, electromechanical and electrofluidic systems, with a controller (14) for the simulation and visual reproduction of system components (25-31) on a display (11), and with electric terminals (13) located adjacent to the display (11) for cable connection to hardware components of the system, wherein optical inputs and/or outputs of the simulated system components on the display (11) are assigned to at least a part of the terminals (13) and wherein the controller (14) comprises means for generating electric voltages at the terminals (13) of assigned outputs of the simulated system components (31) and/or for generating reactions of the simulated system components (25-30) in dependence on voltages externally applied to terminals (13) assigned to inputs of said simulated system components.
