Core schematic elements
If you look at any standard 24V relay PCB, you will see a diode (typically a 1N4007) wired in parallel with the relay coil, pointing opposite to the current flow. This is a . When the 24V power is cut, the magnetic field in the coil collapses, generating a massive high-voltage spike. The diode safely shorts this spike, protecting the control electronics from burning out. 3. The Power Contacts (The Load Circuit) 24V Power Supply Circuit | 9 Circuits - ElecCircuit
