gure 13. Typical Connection with LED
Note:
1. OUT1 will latch the output state during reset.
2. Many modern relays come with a flyback diode pre-ins
talled internal to the relay itself. If the
relay has this diode, ensure the proper relay polarity connected is used. If this diode is not
internal, it should be added externally. A common diode such as 1N4004 will work in most
circumstances.
3.10. Device Status LED
GV55W has three status LEDs that are GSM LED, GPS LED, and PWR LED.
