WebSep 8, 2024 · Flyback diode wiring in a relay circuit. Note that the placement of the flyback diode does not prevent a voltage spike from traveling to some downstream load. Instead, it provides a path with low resistance that reroutes the current, thus the voltage spike at the downstream load will be much lower. Using a simple 1N4007 diode is sufficient to ... WebPump Control According to Water Level (Two-pole Method) (1)When electrode E 1 is not in contact with the conductive liquid as shown in figure 2, the electrical circuit is open, and no current flows between electrodes E 1 and E 3. Consequently relay X does not operate and the contact remains at the b side. (2)When electrode E 1 is in contact with the conductive …
