50 control circuits.
Build every one.

A series of real control circuits, from a start/stop seal-in to a PLC running a drive. Read what each one does and open it straight into PickettPanel. Open it working, or pick Easy (one hidden fault) or Hard (three, with no current flow showing, as on a real panel) and track down what’s wrong with the meter. Then try building it yourself from a blank sheet. The core circuits also carry guided faults with a proper brief. Projects 46–50 are big ones for a real challenge, three of them over 40 parts.
