Figure 7.Typical Connection with a Relay
Note:
1. Many modern relays come with a fly backdiode pre-installed internal to the relay
itself. If the relay has this diode, ensure the relay polarity is properly connected. If this
diode is not internal, it should be added externally. A common diode such as a 1N4004
will work in most circumstances.
