PickettPanel is a place to experiment and develop circuit logic — it is not a substitute for the judgment of a qualified, licensed electrician or engineer, and it does not certify or guarantee that any finished design is safe or compliant.

Use it to explore ideas, test logic, and iterate quickly. The finished, buildable product — verified, reviewed, and made code-compliant — is on you. Before any circuit is built, energized, or relied upon:

Have the design reviewed by a licensed electrician or engineer.
Verify compliance with the National Electrical Code (NEC), IEC 60617, NFPA 79, and all applicable local codes and the Authority Having Jurisdiction (AHJ).
Follow proper lockout/tagout and electrical safety practices at all times.

How to program

Select a tool above, then click a cell on the rung to place it.

NO Contact — closes when input is HIGH
NC Contact — opens when input is HIGH
Coil — energises output when rung is true

Click a placed element to select it, then assign an I/O address.

INPUTS (left side)

One terminal per line

OUTPUTS (right side)

One terminal per line

LOGIC (one rule per output — optional)

OUT = IN (follow) · OUT = NOT IN (invert) · OUT = IN AFTER 3 (on-delay, seconds). Outputs without a rule follow the input on the same row.

Wires already connected to renamed terminals will need to be reconnected. Removing a terminal deletes its wires.

Thanks — that's genuinely useful.
