Figure 14. Typical Connection with a Relay
Warning:
Many modern relays come with a flyback diode pre-installed internal to the relay
itself. If the relay has this diode, ensure the relay polarity connected is properly used. If this
diode is not internal, it should be added externally. A common diode such as a 1N4004 will
work in most circumstances.
