Figure 7. Typical Connection with a Relay
Note:
1. Many modern relays already have the freewheeling diodes inside. If the relay has this
diode, make ensure the polarity of the relay is connected correctly when using it. If not built
in, the diode should be added outside the relay. A common diode such as a 1N4004 will
work in most circumstances.
3.8 LED Status
