How does a dual channel relay work?

How does a dual channel relay work?

The dual-channel relay module contains switching relays and the associated drive circuitry to make it easy to integrate relays into a project powered by a microcontroller. On the left are two terminal blocks, which are used to connect mains wires to the module without soldering.

What is VCC in relay?

VCC : Connected to positive supply voltage (supply power according to relay voltage) GND : Connected to negative supply voltage. IN1: Signal triggering terminal 1 of relay module. IN2: Signal triggering terminal 2 of relay module.

What is 5V 2-channel relay module?

2-Channel 5V Relay Module is a relay interface board, it can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM and so on. It uses a low level triggered control signal (3.3-5VDC) to control the relay. Triggering the relay operates the normally open or normally closed contacts.

How do I connect a 2-channel relay to my Arduino?

Start by connecting VCC pin on the module to 5V on the Arduino and GND pin to ground. Connect the digital pin #6 to the IN1 input pin for controlling the first relay. You’ll also need to place the relay module in line with the AC powered device (lamp in our case) you’re attempting to control.

What is the difference between 1 channel and 2 channel relay?

A 1-channel relay board can switch one load, a 2-channel relay board can switch two loads independently.

What does a channel relay do?

The relay is used for the purpose of protection of the equipment connected with it. These are used to control the high voltage circuit with low voltage signal in applications audio amplifiers and some types of modems.

What is the use of 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 the meaning of 5V relay?

What is a 5V 2-channel relay module?

This is a 5V 2-Channel Relay Module board, Be able to control various appliances, and other equipment with large current. It can be controlled directly by Microcontroller (Raspberry Pi, Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic).

How to control a 2 Channel relay with Arduino?

Using the Arduino to Control a 2 Channel Relay In this example, when a low level is supplied to signal terminal of the 2-channel relay, the LED on the relay will light up. Otherwise, it will turn off. If a periodic high and low level is supplied to the signal terminal, you can see the LED will cycle between on and off.

What is a relay module used for?

Relays are used where it is necessary to control a circuit by a separate low-power signal, or where several circuits must be controlled by one signal. In this lesson, we will show you how the 2-Channel Relay Module works and how to use it with the Osoyoo Uno board to control high voltage devices.

What are the pins on the PCB for the relay?

It has a 1×4 (2.54mm pitch) pin header for connecting power (5V and 0V), and for controlling the 2 relays. The pins are marked on the PCB: GND – Connect 0V to this pin. IN1 – Controls relay 1, active Low! Relay will turn on when this input goes below about 2.0V IN2 – Controls relay 2, active Low!
