Songle 5v Relay Pinout

The above circuit shows a bare minimum concept for a relay to operate.

Songle 5v relay pinout. The working of the project is based on the functioning of the relay and the ability of arduino to control the relay. As mentioned earlier by interfacing arduino with 5v relay module we intend to operate an ac load like lamp. Since the relay has 5v trigger voltage we have used a 5v dc supply to one end of the coil and the other end to ground through a switch. The output current of the digital pin is 40ma a songle 5v relay requires about 72ma.

The arduino can be programmed to turn on the relay when a certain event occurs for example when the temperature of a thermistor gets higher than 30 c. Instructions schematics and tutorial for the popular 4 channel relay module used with arduinos. 5v 8 channel relay module. The only link is by the magnetic field.

This makes it easy as arduino can. Srs 05vdc sl pdf datasheet dc 5v relay songle pdf pinout equivalent replacement schematic manual data circuit parts datasheet. Since the arduino operates at 5v it can t control these higher voltage devices directly but you can use a 5v relay to switch the 120 240v current and use the arduino to control the relay. It is a compact sealed 5 pin type and can control no and nc types.

There are other relay modules that are powered using 3 3v which is ideal for esp32 esp8266 and other microcontrollers. 3 3v 1 channel relay module. Understanding the specs of the songle srdvdc sl c relay will. 18 01 2019 18 01 2019 1 comments on songle relay wiring.

This switch can be anything from a small transistor to a microcontroller or a microprocessor which can perform switching operating. Let us now see how the circuit is designed. Let us discuss the working of the project. 5v 2 channel relay module.

Get a relay module. If so how to wire it up. A simple project in which arduino uno controls a 5v relay is explained here. It can receive a 5v signal and control the power supply up to 250v 10a.

The switching contacts of a relay are completely isolated from the coil and hence from the arduino. 5v 1 channel relay module. First thing is we used a 5v relay in this project. It is a relay for 5v signal control that can be applied and used in areas requiring various contact control.
