  • Relays are most commonly used switching device in electronics.
  • Before we proceed with the circuit to drive the relay we have to consider two important parameter of the relay.
  • Trigger Voltage is the voltage required to turn on the relay that is to change the contact from Common->NC to Common->NO.
  • The other parameter is your Load Voltage & Current.
  • This is the amount of voltage or current that the NC,NO or Common terminal of the relay could withstand.
  • In our case for DC it is maximum of 30V and 10A.
  • Make sure the load you are using falls into this range. 

Relay Working - How to Use Relay

  • The above circuit shows a bare-minimum concept for a relay to operate.
  • Since the relay has 5V trigger voltage we have used a +5V DC supply to one end of the coil and the other end to ground through a switch.
  • This switch can be anything from a small transistor to a micro-controller or a microprocessor which can perform switching operating.
  • You can also notice a diode connected across the coil of the relay, this diode is called the Fly back Diode.
  • The purpose of the diode is to protect the switch from high voltage spike that can produced by the relay coil.
  • As shown one end of the load can be connected to the Common pin and the other end is either connected to NO or NC.
  • If connected to NO the load remains disconnected before trigger and if connected to NC the load remains connected before trigger.
