ELEGOO Dupont Wire and 4-Channel Relay Module User Manual

1. Produit terminéview

This bundle provides essential components for various electronic projects, particularly those involving microcontrollers like Arduino. It includes a set of multicolored Dupont wires and a 4-channel DC 5V relay module.

1.1 Dupont Wires

The ELEGOO 120-piece Dupont wire kit consists of three types of jumper wires: male-to-female, male-to-male, and female-to-female. These wires are flexible and can be separated to form custom assemblies, supporting both standard and non-standard pin configurations. They are ideal for connecting components on breadboards, prototyping shields, and microcontrollers.

1.2 4-Channel DC 5V Relay Module

The 4-channel relay module allows a microcontroller to control high-power devices that operate at AC 250V 10A or DC 30V 10A. This module is designed to be controlled by 5V logic signals (active low), making it compatible with popular microcontrollers such as Arduino, AVR, PIC, and ARM.

2. Instructions de configuration

2.1 Connecting the Relay Module to a Microcontroller

1. Connexion électrique : Connect the VCC pin of the relay module to the 5V output of your microcontroller (e.g., Arduino). Connect the GND pin of the relay module to the GND pin of your microcontroller.
2. Connexion du signal de commande : Connect the IN1, IN2, IN3, and IN4 pins of the relay module to digital output pins on your microcontroller. These pins will control the individual relays.
3. Connexion de charge : For each relay, identify the Common (COM), Normally Open (NO), and Normally Closed (NC) terminals. Connect the device you wish to control to the appropriate terminals. For example, to switch a device on when the relay is activated, connect one side of the device to the power source and the other side to the COM terminal, then connect the NO terminal to the other side of the power source.

2.2 Using Dupont Wires

• Breadboard Connections: Use male-to-male wires to connect components to a breadboard.
• Microcontroller to Breadboard: Use male-to-female wires to connect microcontroller pins to components on a breadboard.
• Component to Component: Use female-to-female wires to connect two components with male headers.
• Longueurs personnalisées : Wires can be pulled apart from the ribbon to create individual jumpers of desired lengths.

3. Mode d'emploi

The ELEGOO 4-channel relay module operates with an active-low logic. This means that to activate a relay (close the circuit between COM and NO, and open between COM and NC), you must send a LOW signal (0V) to its corresponding IN pin from your microcontroller. To deactivate a relay (open the circuit between COM and NO, and close between COM and NC), send a HIGH signal (5V) to its IN pin.

• Activation du relais : Set the microcontroller pin connected to INx to LOW.
• Relay Deactivation: Set the microcontroller pin connected to INx to HIGH.

Ensure that the load connected to the relay does not exceed the maximum ratings of AC 250V 10A or DC 30V 10A.

4. Entretien

• Stockage: Store the Dupont wires and relay module in a dry, dust-free environment to prevent corrosion and damage.
• Manutention: Handle electronic components with care. Avoid excessive force when inserting or removing wires and modules.
• Nettoyage: Si nécessaire, nettoyez délicatement le module avec un chiffon doux et sec. Évitez d'utiliser des liquides ou des nettoyants abrasifs.
• Inspection: Periodically inspect wires for frayed insulation or bent pins. Replace damaged wires to ensure reliable connections.

5. Dépannage

• Relais non activé :
  • Verify power connections (VCC to 5V, GND to GND).
  • Ensure the control signal is active-low (sending LOW to IN pin to activate).
  • Check if the microcontroller pin is correctly configured as an output.
  • Inspect Dupont wire connections for looseness or damage.
• Connexions intermittentes :
  • Ensure Dupont wire pins are straight and fully inserted into headers or breadboard holes.
  • Check for bent or corroded pins on the relay module or microcontroller.
• Device Not Switching:
  • Confirm the load is correctly wired to the COM and NO/NC terminals of the relay.
  • Assurez-vous que le volume de la chargetage and current requirements do not exceed the relay's maximum ratings (AC 250V 10A, DC 30V 10A).
  • Test the load independently to ensure it is functional.
