CoilPath: Control Circuits

With CoilPath you draw electrical control circuits, run them in the simulator and learn through tasks. It is made for electricians, electrical students and anyone who works with control panels.

Draw schematics
• Draw power and control circuits with IEC symbols: circuit breakers, contactors, overload relays, push buttons, timer relays, phase monitoring relays, level relays, sensors and motors.
• Draw the wiring with real device views; wires go to the screw terminals of each device.
• Symbols connect by themselves when they line up. Your projects are saved on your device.

Run the simulation
• Close the breakers and press the buttons: see contactors energize, the path the current takes and the direction the motor turns.
• Timer relays count, overload relays trip on overcurrent, and you can measure voltages with the multimeter.
• Switch between the schematic and the device wiring; the simulation keeps running where it was.

Learn through tasks
• 200 tasks in 14 chapters: run the circuit, add the missing part, find the fault.
• Hints open one by one; when you finish, you see how the circuit works. Collect stars.

Ready-made circuit library
• 62 ready-made circuits: basic connections, seal-in and forward-reverse, timer relay circuits, protection and sensors, star-delta and Dahlander, pump and float switch circuits.
• PLC applications: follow the current through the ladder program and watch inputs and outputs in the simulation.
• Frequency drive applications: keypad, potentiometer, forward-reverse. Change parameters and see how the speed changes.
• HMI applications: design an operator panel, connect it to the PLC and control the circuit from the panel in the simulation.
• Solar PV applications: build a rooftop system with PV panels, DC isolator, surge protection, inverter and bidirectional meter; change sunlight and temperature and watch the inverter's live values.

Also
• 7 languages: Türkçe, English, Deutsch, Français, Italiano, Español, Português (Brasil).
• Works offline, no account needed.
• Send the bugs you find and your requests from the feedback section in the app; new versions are built around them.
