4 Channel 5V Relay Board
This 4 channel 5V relay module is a low-pull, high-release relay module and features an energisation status indicator light; the release status LED is off.
By default, this is a 5V relay module that uses JD-VCC for the relay power and is compliant with international safety standards, control and load areas isolation trenches.
The 4 Channel Relay Module is a convenient board that can be used to control high voltage, high current loads such as motors, solenoid valves, lamps and AC loads. It is designed to interface with microcontrollers such as Arduino, PIC, etc.
The relay terminal (COM, NO and NC) is being brought out with a screw terminal. It also comes with an LED to indicate the status.
The 4 channel relay module can be used to control various appliances and other types of equipment with a large current. The maximum output of the relay module is AC250V 10A and DC5V 10A.
Applications:
- Switching mains loads
- Home automation
- Battery backup
- High current load switching
Also check the 8 Channel 5V 10A Relay Module.
Also, check our relay switch collection.
Package Includes:
- 1 x 4 channel 5v Relay

1. What is a 4 channel relay module?
- The 4 Channel Relay Module is a convenient board that can control high voltage and high current loads such as motor, solenoid valves, lamps, and AC load. It is designed to interface with microcontrollers such as Arduino, PIC, etc.
2. How does 4 channel relay work?
- The 4 channel Relays are the switches that open and close circuits electronically. Relays control one electrical circuit by opening and closing contacts in another circuit. When a relay contact is normally open (NO), there is an open contact when the relay is not energized. When a relay contact is Normally Closed (NC), there is a closed contact when the relay is not energized. In either case, applying electrical current to the contacts will change their state
3. What are the components present on a four-channel relay module?
- The major components present on the 4-channel 5V relay board are terminal blocks, male headers, transistors, optocouplers, diodes, and LEDs.
4. How do you connect 4 Channel relay modules to Arduino?
- NC: Normally closed 120-240V terminal
- NO: Normally open 120-240V terminal
- C: Common terminal
- Ground: Connects to the ground pin on the Arduino 5V
- Vcc: Connects the Arduino’s 5V pin
- Signal: Carries the trigger signal from the Arduino that activates the relay
5. What are Normal Open and Normal Closed in a 4-channel 5V relay board?
- The 4 channel relay module has two different types of electrical contacts inside normally open (NO) and normally closed (NC). The one you use will depend on whether you want the 5V signal to turn the switch on or turn the switch off. The 120-240V supply current enters the relay at the common (C) terminal in both configurations. To use the normally open contacts, use the NO terminal. To use the normally closed contacts, use the NC terminal.
