And if you want to drive them with even less current, use a "Darlington Pair" transistor setup and very little current will energize them. Arduino KY-019 Relay Module is used to control AC circuits, the relay acts as a switch that responds to a signal received from the Arduino, it has an integrated LED that indicates if the signal is high or low. Reactions: TimGavinq. How to Use a Relay? Since an inductor (the relay coil) cannot change it’s current instantly, the flyback diode provides a path for the current when the coil is switched off. On the switched circuit side of the module, you’ll see the three switched connection points marked with the diagram shown below (the labels NO, Common, and NC are mine). Then connect the loads as shown in the circuit diagram. Includes back-EMF protection and LEDs so you can easily see the state of the outputs. We have put a three pin screw terminal blocks (NC, Nuteral, NO) for connecting appliances. Reply Muhammad Ansar. Another notable convention in relay circuits and their ladder diagrams is that each and every wire in the circuit is labeled with a number corresponding to common connection points.
