Relay With Diode Or Resistor at Madison Wardell blog

Relay With Diode Or Resistor. There are two main types of relays: A diode is put in parallel with a relay coil (with opposite polarity) to prevent damage to other components when the relay is turned off. They are sometimes called flywheel. But while electrical relays can be used to allow low power electronic or computer type circuits to switch relatively high currents or voltages both. A resistor in series with the diode can make the. The use of a flyback diode in a relay circuit prevents huge voltage spikes from arising when the power supply is disconnected. In other words, a diode will conduct. A diode parallel to the coil is probably the most often used way, but there are other ways, like a snubber (r+c) or a zener diode to ground. Placing a diode in reverse bias across a relay's coil eliminates voltage spikes by going into conduction before a large voltage can form across the coil. Here's an example schematic i found online: In practice, you use them the same. Resistors or diodes are sometimes fitted across the coil of the relay to stop/reduce these spikes travelling back into the control circuit and damaging sensitive components. You can easily make a relay driver circuit with a transistor, a current limiting resistor (to turn the transistor on and off), and a diode in parallel with the relay.
