The virtual laboratory stand «Relay-Contactor Circuits for Electric Drive Control» is intended for simulation training in the principles of constructing relay-contactor control circuits for a three-phase asynchronous electric drive using standard electrical components – circuit breakers, contactors, relays, push-button posts, etc.



Main functions of the software product:
- Construction and editing of a schematic diagram of an electrical circuit;
- Construction and editing of a simulation model of a laboratory stand;
- Software simulation of an assembled electrical circuit with the ability to interactively change the state of devices;
- Simulated measurement of voltage in a circuit using a virtual multimeter;
- Working with user project files;
- Interaction with a physical relay board to implement software control of the electric drive (optional).



The graphics component of the software uses the OpenGL 2.0 component base.
