In this guide you will set up the 2 channel relay module to control some LEDs with a toggle switch.
2 relay module connection. The following figure shows the relay module pinout. 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. Lets set up our relay module to switch on a lamp.
2 Channel 5V Optical Isolated Relay Module This is a LOW Level 5V 2-channel relay interface board and each channel needs a 15-20mA driver current. 2 or more LEDs. The light bulb has one of the 120V wire spliced to connect the end connected to the power plug to the COM Common Pin of the Relay module and the one going to the lamp is connected to the NC Normally Closed Pin.
Relay base for industrial relay with 2 or 4 changeover contacts screw connection plug-in option for inputinterference suppression modules for mounting on NS 3575. Relay Datasheet. 2021 if ordered now.
I am using the Arduino Uno as of now and the IN1 and IN2 from the relay module are in pins 6 and 7 respectfully. The single-channel relay module is much more than just a plain relay it comprises of components that make switching and connection easier and act as indicators to show if the module is powered and if the relay is active or not. Get a relay module.
2 Screw connection 4 changeover contacts Input voltage. If you are using this module to control high voltages like something connected to a wall socket please exercise caution. Connect the components based on the figure shown in the wiring diagram using pin connectors.
A single relay is capable of controlling two ACDC devices simultaneously. Terminal 2 is similar to terminal 1except that the control port is INT2 INT 1- Relay 1 control port INT 2- Relay 2 control port Usage. It is equipped with highcurrent relays.
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. Relay is a switch which makes or loses the connection between two different circuits. Onboard high performance microprocessor STM8S103 and ESP-01 WiFi modules.
The below image shows the basic connections required for connecting a 5V power supply to drive an LED using one channel of the relay module. NO- Normally Open in which case NO is disconnected with COM1 when INT1 is set low and connected when INT1 is high. We use a breadboard to connect.
Relay base function plug-in module power contact relay and retaining bracket approval in accordance with ATEXIECEx Zone 2 and Ex Zone Class I Div. 5V 8-channel relay module. This terminal is connected with the load that we want to switch with the relay module.
We connect the IR Motion sensor OUT to Pin 4 and the Relay IN1 to Pin 8. 2 or more LEDs. Expected to leave our warehouse on 22 Dec.
It can be used to control various appliances and equipment with large current. Relay is an electromechanical device that uses an electric current to open or close the contacts of a switch. So 2 relay module is able to control four ACDC devices at the same time.
2 Relay Module is an electronic device consists of two relays as its major components. The code given below is the same I used in my video. VCC and COM pin is connected to the 5V power supply GND pin is connected to the GND IN1 and IN2 pins are connected to the digital IO pin.
Connect the digital pin 6 to the IN1 input pin for controlling the first relay. Start by connecting VCC pin on the module to 5V on the Arduino and GND pin to ground. Relay base - RIF-2-BSC4X21.
33V 1-channel relay module. 2 channel 5V 10A relay module Pin connectors Breadboard USB cable 1. Each submodular of the relay has one NCnomalclose one NOnomalopen and one COMCommon.
2 220 ohm resistors. Youll also need to place the relay module in line with the AC powered device lamp in our case youre attempting to control. Next come to the two relays.
Signal triggering terminal 1 of relay module IN2. Connected to negative supply voltage IN1. The 5V dual WiFi relay module uses ESP-01 as the WiFi module and is compatible with 8 bit MCU chips.
I modified the code that was provided in order to control 2 relays instead of one. As marked on the body of the relay. As the name of the normally close terminal suggests it is normally connected with the COM pin and forms a closed circuitBut this normally closed connection breaks when the relay is activated by applying an active high or active low signal to the signal pin of the relay module from a.
5V 1-channel relay module. 5V 2-channel relay module. Only a simple configuration process can realize the wireless control of the 2 way relay by using the mobile phone APP in the lan.
In this guide you will set up the 2 channel relay module to control some LEDs with a toggle switch. Pricing and availability information is currently not available for this product. Quick Start Guide WARNING.
Signal triggering terminal 2 of relay module. Pre-assembled relay module consisting of. HIGH VOLTAGE IS DANGEROUS.
Ive attached the code also. Since I have used a bread board power supply on the output side of the relay module it may be confusing to understand the connections. Ive attached a picture below of both the relay module and the bluetooth JY-MCU HC 05.
Connected to positive supply voltage supply power according to relay voltage GND. If you are using this module to control high voltages like something connected to a wall socket please exercise caution.
