15 Relay Diode Schematic

15 Relay Diode Schematic. The diode is needed cause the voltage will rise high if you suddenly change the voltage at the but due to the minus in front you can add a diode in the false direction parallel to the relay. Relays are frequently used in our electronics applications specially when we need to drive high loads from microcontroller circuits.

How to use relay example of basic schematic circuit diagram:this lesson will guide you about information basic schematic circuit diagram. Electrical symbols and electronic circuit symbols are used for drawing schematic diagram. The diode is called a flyback diode which help suppress the sudden voltage spike on the relay coil when the current is removed from the circuit.

15 Relay Diode Schematic. The freewheeling diode works as voltage surge clamp circuit which clamps the excess voltage spike thereby bypassing the current. I see that its technically a diode, a coil relays with moving contacts that bridge two fixed contacts (as your schematic seems to indicate) are. A relay is an electrically operated switch. The snubber diode backwards across the relay coil absorbs the reverse voltage inductive spike that occurs when turning off the coil (i.e., v=ldi/dt).
