5 Pin 48V DC Coil Voltage Electromagnetic Power Relay
5 Pin 48V DC Coil Voltage Electromagnetic Power Relay
The 5 Pin 48V DC Coil Voltage Electromagnetic Power Relay is an electro-mechanical switching device designed to control high-power circuits in a variety of applications. It operates on a 48V DC coil voltage and features five pins, which include a normally open (NO) contact, a normally closed (NC) contact, a common (COM) terminal, and two coil terminals.
The relay's primary function is to allow a low-power electrical signal to control a high-power circuit. When a 48V DC voltage is applied to the coil terminals, the relay's internal electromagnet is energized, causing the normally open (NO) contact to close and the normally closed (NC) contact to open. This switching action allows the relay to control the flow of electrical current in the connected circuit.

Ensure the relay is used within its specified operating temperature range and voltage ratings to prevent damage or premature failure.
Use proper safety precautions when handling the relay, as it may be hot or carry high voltage during operation.
Follow proper wiring and installation procedures to ensure reliable operation and prevent electrical shock or fire hazards.
Component Documentation: 5 Pin 48V DC Coil Voltage Electromagnetic Power RelayOverviewThe 5 Pin 48V DC Coil Voltage Electromagnetic Power Relay is a type of relay module that allows you to control high-voltage devices with a low-voltage signal. It is commonly used in IoT projects, industrial control systems, and automation applications. This relay module features a 48V DC coil voltage and can switch up to 10A of current.PinoutThe relay module has 5 pins:VCC: Positive power supply (48V DC)
GND: Ground
IN: Input signal pin (low-voltage signal to control the relay)
COM: Common pin (connected to the normally open (NO) or normally closed (NC) pin)
NO/NC: Normally open (NO) or normally closed (NC) pin (dependent on the relay's configuration)Code Examples### Example 1: Basic Relay Control using ArduinoIn this example, we will use an Arduino board to control the relay module.Hardware Connections:Connect the VCC pin of the relay module to the 48V DC power supply.
Connect the GND pin of the relay module to the GND pin of the Arduino board.
Connect the IN pin of the relay module to a digital output pin of the Arduino board (e.g., pin 13).
Connect the COM pin of the relay module to the positive terminal of a load (e.g., a LED or a small motor).
Connect the NO/NC pin of the relay module to the negative terminal of the load.Arduino Code:
```c
const int relayPin = 13; // Choose a digital output pin on the Arduino boardvoid setup() {
pinMode(relayPin, OUTPUT);
}void loop() {
digitalWrite(relayPin, HIGH); // Turn the relay ON
delay(1000); // Wait for 1 second
digitalWrite(relayPin, LOW); // Turn the relay OFF
delay(1000); // Wait for 1 second
}
```
### Example 2: Relay Control using Raspberry Pi and PythonIn this example, we will use a Raspberry Pi board to control the relay module using Python.Hardware Connections:Connect the VCC pin of the relay module to the 48V DC power supply.
Connect the GND pin of the relay module to the GND pin of the Raspberry Pi board.
Connect the IN pin of the relay module to a GPIO pin of the Raspberry Pi board (e.g., GPIO 17).Python Code:
```python
import RPi.GPIO as GPIO
import timeGPIO.setmode(GPIO.BCM)
relay_pin = 17 # Choose a GPIO pin on the Raspberry Pi board
GPIO.setup(relay_pin, GPIO.OUT)try:
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
except KeyboardInterrupt:
GPIO.cleanup()
```
