Ileta turns your phone into a control panel trainer. Draw relay and contactor circuits the way you learned them in class, press Run and watch them come to life.

HOW IT WORKS
Pick a part from the palette, place it on the grid and drag from terminal to terminal to wire it. Press RUN and operate the circuit like the real thing: push the buttons, flip the switches and watch contactors pull in, seal-in circuits hold, timers count down and motors start. Live wires light up in their phase colours, so you can follow the current step by step.

Made a mistake? Ileta tells you in plain words (a short circuit, a missing interlock, a motor running on two phases), so you learn why a circuit fails, not just that it does.

WHAT'S INSIDE
• Supplies: phases L1/L2/L3, neutral, earth, DC, transformer and power supply
• Push buttons, switches, emergency stop, selector and sensors (limit, pressure, level, flow, thermostat)
• Relays, contactors, timer relays, flasher and impulse relays
• Protection: overload relay, motor breaker, circuit breakers, RCDs, fuses, phase monitor
• Motors: single and three-phase, star-delta and two-speed Dahlander
• Indicator lamp, buzzer, solenoid valve, heater and traffic light
• 15 ready-made example circuits, from a simple start/stop to star-delta
• Save your projects, share them as files and pick up where you left off
• Light and dark themes, adjustable wire colours and size, portrait and landscape
• Eight languages, works fully offline. No account, no ads.

WHO IS IT FOR
Students, teachers, engineers, hobbyists and anyone curious about electrical circuits or eager to learn how they work.

Some advanced parts and file import/export are part of Ileta Pro (yearly or one-time purchase). You can place and wire them in the free version and see exactly what you get before you decide.
