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.

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 the use of 8 channel relay module?
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.
How do I connect 8 channel relay module with Arduino?
- Remove blue jumper.
- Connect JD-VCC and GND from the Relay Module to a Separate 5VDC Supply (1Amp or greater)
- Connect VCC from the Relay Module to 5V on your Arduino.
- Connect required control signals as shown.
- Note: DO NOT connect GND from the Relay Module to your Arduino.
How do I make a relay module?

How does 5V relay module work?
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 5V 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 many pins are present in relay module?
13 pins
Explanation: The Relay (Dual Channel) Module has 13 pins which includes the 2 Vcc’s, 2 GND’s, IN1 and IN2 which are the two input channels, 2 NC’s, 2 NO’s and 2 COM’s. All these pins have very specific functions and input patterns which need to be connected in perfect order in order for the module to function properly.
How do you create a relay module?
How does a 5V relay module work?
How do you use 5V relay module?
Coming to the load part i.e. the lamp, hot wire from the mains supply is connected to one terminal of the lamp. Other terminal of the lamp is connected to Normally Open (NO) contact of the 5V Relay. Finally, the neutral wire from the mains is connected to the Common (COMM) contact of the relay.
What is relay circuit diagram?
Relays are switches that open and close circuits electromechanically or electronically. Relays control one electrical circuit by opening and closing contacts in another circuit. As relay diagrams show, when a relay contact is normally open (NO), there is an open contact when the relay is not energized.
