Analog Input or Digital out Connection 5.10. Digital Outputs There are three digital outputs on GV300CAU. All are of open drain type and the maximum drain current is 150 mA.
GV300CAU Series User Manual Figure 14. Typical Connection with a Relay Figure 15. Typical Connection with a LED Note: OUT1 will latch the output state during reset. Warning: Many modern relays come with a flyback diode pre-installed internal to the relay itself. If the relay has this diode, insure 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.
