5v 1 channel relay module circuit diagram. 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. 1 good in safety. Wide range of controllable voltage. Let us learn how to use one in our circuits based on the requirement of our project.
The features of 1 channel relay module are as follow. Being able to control high load current which can reach 240v 10a. The features of 1 channel relay module are as follow. 5v and gnd and connect the control signal from arduino to control.
1 channel 5v relay module for arduino with optocoupler 62 00 dupont wire male to female jumper wires ribbon cable pack of 40 79 00 141 00 for 2 item s. Circuit diagram and explanation. 2 1 channel high voltage system output meeting the needs of single channel control 3 wide range of controllable voltage. How to use a relay.
Although the circuit diagram explains the detailed connections practically we didn t need to make all the connections. So connect the 5v and the ground of the arduino with the 5v and the ground of the relay module. In this example we will connect the relay module with arduino in the normally open state. Also the electrical paths for the ac lines on the relay module should be wide enough min 3mm as short as possible separated from any other path on the pcb and not too close to each other.
4 if the relay should switch ac loads the use of an opt isolator is recommended to separate the control circuit from the switching circuit relay. 3v relay 12v relay 1 channel relay module 4 channel relay module. In power system and high voltage system the lower current can control the higher one. Relays are most commonly used switching device in electronics.
1 channel high voltage system output meeting the needs of single channel control. Most relay modules whether 5v or 12v will come with the aforementioned connection and hence all you need is to give power supply to the relay module i e.
