Songle 5v Relay Pinout

As mentioned earlier by interfacing arduino with 5v relay module we intend to operate an ac load like lamp.

Songle 5v relay pinout. This switch can be anything from a small transistor to a microcontroller or a microprocessor which can perform switching operating. 5v 2 channel relay module. Understanding the specs of the songle srdvdc sl c relay will. 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.

If so how to wire it up. 5v 8 channel relay module. 18 01 2019 18 01 2019 1 comments on songle relay wiring. Instructions schematics and tutorial for the popular 4 channel relay module used with arduinos.

The working of the project is based on the functioning of the relay and the ability of arduino to control the relay. Let us discuss the working of the project. A relay that uses 5v which is widely used in arduino. A relay accomplishes this by using the 5v outputted from an arduino pin to energize the electromagnet which in turn closes an internal physical switch to turn on or off a higher power circuit.

Srs 05vdc sl pdf datasheet dc 5v relay songle pdf pinout equivalent replacement schematic manual data circuit parts datasheet. First thing is we used a 5v relay in this project. It is a compact sealed 5 pin type and can control no and nc types. 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.

Get a relay module. The switching contacts of a relay are completely isolated from the coil and hence from the arduino. This makes it easy as arduino can. The only link is by the magnetic field.

3 3v 1 channel relay module. 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. Let us now see how the circuit is designed. 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. 5v 1 channel relay module. The above circuit shows a bare minimum concept for a relay to operate. There are other relay modules that are powered using 3 3v which is ideal for esp32 esp8266 and other microcontrollers.
