Pin Configuration

  • DC 6V to 30V One Way Relay Module Documentation
  • Pin Description:
  • The DC 6V to 30V One Way Relay Module has 5 pins, labeled as follows:
  • 1. VCC (Voltage Supply):
  • Pin Description: Power supply pin for the relay module.
  • Voltage Range: 6V to 30V DC.
  • Function: Provides power to the relay module's internal circuitry.
  • 2. GND (Ground):
  • Pin Description: Ground pin for the relay module.
  • Function: Provides a common ground reference for the relay module.
  • 3. IN (Input):
  • Pin Description: Trigger input pin for the relay.
  • Voltage Level: Active-low, meaning a low voltage (0V) signal triggers the relay, while a high voltage (VCC) signal de-activates it.
  • Function: When the input pin is connected to GND (0V), the relay is activated, and the normally open (NO) and normally closed (NC) contacts switch.
  • 4. NO (Normally Open):
  • Pin Description: Normally open contact of the relay.
  • Function: When the relay is activated, the NO pin connects to the COM pin, allowing the load circuit to turn on.
  • 5. NC (Normally Closed) / COM (Common):
  • Pin Description: Normally closed contact and common pin of the relay.
  • Function: When the relay is de-activated, the NC pin connects to the COM pin, allowing the load circuit to turn off. When the relay is activated, the NO pin connects to the COM pin.
  • Connection Structure:
  • To connect the pins, follow this structure:
  • Power Supply:
  • + Connect VCC to a DC power source (6V to 30V) through a suitable voltage regulator or power supply module.
  • + Connect GND to the ground terminal of the power source.
  • Trigger Input:
  • + Connect IN to a digital output pin of a microcontroller (e.g., Arduino) or a logic gate.
  • + Ensure the output voltage of the microcontroller or logic gate is within the relay module's input voltage range (VCC).
  • Load Circuit:
  • + Connect the load circuit (e.g., LED, motor, or solenoid) to the NO and COM pins.
  • + The load circuit will turn on when the relay is activated (IN pin is connected to GND) and turn off when the relay is de-activated (IN pin is connected to VCC).
  • Important Notes:
  • Ensure the power supply voltage and current meet the relay module's specifications.
  • Use a suitable voltage regulator or power supply module to regulate the voltage to the relay module.
  • Keep the relay module away from high-temperature areas and ensure good ventilation to prevent overheating.
  • Follow proper safety precautions when working with electrical circuits and ensure the load circuit is designed and constructed safely.

Code Examples
Here are a few examples of how to use this relay module in different contexts:
Example 1: Controlling a 12V Fan using Arduino
In this example, we'll use an Arduino board to control a 12V fan using the relay module.
```cpp
const int relayPin = 2;  // Pin connected to the relay module's IN pin
void setup() {
  pinMode(relayPin, OUTPUT);
}
void loop() {
  digitalWrite(relayPin, HIGH);  // Turn the fan on
  delay(5000);
  digitalWrite(relayPin, LOW);   // Turn the fan off
  delay(5000);
}
```
Example 2: Controlling a 24V Solenoid Valve using Raspberry Pi
In this example, we'll use a Raspberry Pi to control a 24V solenoid valve using the relay module.
```python
import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BCM)
relay_pin = 17  # Pin connected to the relay module's IN pin
GPIO.setup(relay_pin, GPIO.OUT)
while True:
    GPIO.output(relay_pin, GPIO.HIGH)  # Turn the solenoid valve on
    time.sleep(5)
    GPIO.output(relay_pin, GPIO.LOW)  # Turn the solenoid valve off
    time.sleep(5)
```
Example 3: Controlling a 12V LED Strip using ESP32
In this example, we'll use an ESP32 board to control a 12V LED strip using the relay module.
```cpp
const int relayPin = 4;  // Pin connected to the relay module's IN pin
void setup() {
  pinMode(relayPin, OUTPUT);
}
void loop() {
  digitalWrite(relayPin, HIGH);  // Turn the LED strip on
  delay(5000);
  digitalWrite(relayPin, LOW);   // Turn the LED strip off
  delay(5000);
}
```
Caution
Ensure the input voltage to the relay module is within the specified range (6V to 30V DC).
 Use a suitable heatsink if you're switching high-current loads.
 Avoid using this module to control inductive loads (such as motors) without proper filtering and protection.
