What does an 8 channel relay do?
Introduction. This is a 8-channel LOW level trigger relay and it can be applied to Arduino and Raspberry Pi. Relays are suitable for driving high power electronic devices such as lights, electric fans and air condition. A relay can be used to control high voltages with a low voltage by connecting it to an MCU.
What is relay module?
The relay module is an electrically operated switch that can be turned on or off deciding to let current flow through or not. They are designed to be controlled with low voltages like 3.3V like the ESP32, ESP8266, etc, or 5V like your Arduino.

How do relay modules work?
A power relay module is an electrical switch that is operated by an electromagnet. When electrical current is passed through a coil, it generates a magnetic field that in turn activates the armature. This movement of the movable contacts makes or breaks a connection with the fixed contact.
How does an 8 channel relay work?
The eight-channel relay module contains eight 5V relays and the associated switching and isolating components, which makes interfacing with a microcontroller or sensor easy with minimum components and connections. Each relay on the board has the same circuit, and the input ground is common to all eight channels.
What is 5V relay module?
A 5v relay is an automatic switch that is commonly used in an automatic control circuit and to control a high-current using a low-current signal. The input voltage of the relay signal ranges from 0 to 5V.
What is 8 Channel relay module?
This 8 Channel Relay module can adopt most common range of microcontrollers, such as Arduino, Raspberry Pi, AVR, PIC, ARM with digital outputs to control larger loads devices like AC or DC Motors, Electromagnets, Soleniod, Incandescent light bulbs, Actuators and any another devices that you want to drive with in the relay.
How many channels does an Arduino relay module have?
This relay module has two channels (those blue cubes). There are other models with one, four and eight channels. This module should be powered with 5V, which is appropriate to use with an Arduino. There are other relay modules that are powered using 3.3V, which is ideal for ESP32, ESP8266, and other microcontrollers.
How to control an AC relay module with Arduino?
Controlling a relay module with the Arduino is as simple as controlling an output – you just need to send HIGH or LOW signals using an Arduino digital pin. With the relay module you can control almost any AC electronics appliances (not just lamps). We hope you’ve found this guide useful.
What is the pinout of the relay module?
Relay Pinout. The following figure shows the relay module pinout. The six pins on the left side of the relay module connect high voltage, and the pins on the right side connect the component that requires low voltage—the Arduino pins.
