24V Relay Cube

24V Relay Cube Documentation

Overview

The 24V Relay Cube is a powerful and compact relay module designed for IoT applications. It features a single relay output, capable of switching loads up to 24V at 10A. The module is equipped with a phototriac coupler for isolation and protection. The relay is controlled by a digital signal from a microcontroller or other logic device.

Pinout

The 24V Relay Cube has the following pinout:

VCC: 5V DC power supply
 GND: Ground
 IN: Digital input for relay control (active high)
 COM: Common terminal for relay output
 NC: Normally closed terminal for relay output
 NO: Normally open terminal for relay output

Code Examples

### Example 1: Using the 24V Relay Cube with Arduino

In this example, we'll use an Arduino Uno to control the 24V Relay Cube. We'll connect the relay module to the digital output pin 2 of the Arduino.

```c
#define RELAY_PIN 2 // Define the digital output pin for the relay

void setup() {
  pinMode(RELAY_PIN, OUTPUT); // Set the relay pin as an output
}

void loop() {
  digitalWrite(RELAY_PIN, HIGH); // Turn the relay ON
  delay(1000); // Wait for 1 second
  digitalWrite(RELAY_PIN, LOW); // Turn the relay OFF
  delay(1000); // Wait for 1 second
}
```

### Example 2: Using the 24V Relay Cube with Raspberry Pi (Python)

In this example, we'll use a Raspberry Pi to control the 24V Relay Cube using Python. We'll connect the relay module to GPIO pin 17 of the Raspberry Pi.

```python
import RPi.GPIO as GPIO
import time

GPIO.setmode(GPIO.BCM) # Set the GPIO mode to BCM
relay_pin = 17 # Define the GPIO pin for the relay
GPIO.setup(relay_pin, GPIO.OUT) # Set the relay pin as an output

while True:
    GPIO.output(relay_pin, GPIO.HIGH) # Turn the relay ON
    time.sleep(1) # Wait for 1 second
    GPIO.output(relay_pin, GPIO.LOW) # Turn the relay OFF
    time.sleep(1) # Wait for 1 second
```

### Example 3: Using the 24V Relay Cube with ESP32 (MicroPython)

In this example, we'll use an ESP32 board to control the 24V Relay Cube using MicroPython. We'll connect the relay module to GPIO pin 18 of the ESP32.

```python
import machine
import time

relay_pin = machine.Pin(18, machine.Pin.OUT) # Define the GPIO pin for the relay

while True:
    relay_pin.value(1) # Turn the relay ON
    time.sleep(1) # Wait for 1 second
    relay_pin.value(0) # Turn the relay OFF
    time.sleep(1) # Wait for 1 second
```

Note: In all examples, ensure that the 24V Relay Cube is powered from a suitable 5V DC power source, and the load connected to the relay output is rated for 24V at 10A or less.
