4.3 Power Connection

Connect a 5V DC power supply to the power input jack on the board. Ensure the power supply provides stable 5V DC to prevent damage to the module.

4.4 Network Connection

Connect a standard Ethernet cable from your network router or switch to the RJ45 Ethernet port on the relay board. The board will attempt to establish a network connection automatically.

4.5 Relay Connections

The board features a green terminal block for connecting external devices to the relays. Each relay has normally open (NO) and normally closed (NC) contacts. Refer to the silkscreen on the board for specific pin assignments. Connect your electrical equipment (e.g., lights, motors) to the appropriate relay contacts based on your application requirements.

4.6 Software and Firmware

For detailed instructions on software configuration, programming, and firmware updates, please refer to the manufacturer's official resources. The product description mentions download links for instructions and code, and firmware. It is recommended to check the Walfront official website for the most current and secure versions of these resources.

5. Operating Instructions

5.1 Network Modes

The relay board supports three primary network operating modes:

• TCP Server Mode: The module acts as a server, listening for incoming connections. Up to four client connections can be maintained simultaneously.
• TCP Client Mode: The module initiates a connection to a specified remote TCP server.
• UDP Mode: The module sends and receives data using the UDP protocol, suitable for broadcast or multicast applications.

Configuration of these modes typically involves setting parameters such as IP address, port number, and target server details through the provided software or web interface (if available).

5.2 Remote Control

Once configured and connected to the network, the relay board can be controlled remotely. This includes controlling it from a mobile phone, computer, or other network-enabled devices. The module's ability to control across gateways allows for integration into larger network infrastructures.

5.3 User-Defined Settings

The module allows for customization:

• User-Defined Name: Assign a unique name to the module, eliminating the need to remember IP addresses, especially in environments with multiple devices.
• Heartbeat Packet Time: Configure the heartbeat interval to ensure reliable detection of offline network conditions and prompt restoration.

5.4 Basic Control Flow (Conceptual)

Typically, control commands are sent over the network to the module. These commands, specific to the module's firmware, instruct the relays to switch ON or OFF. For example, a command might be sent to activate Relay 1, which then closes its NO contact, turning on a connected light.

6. Maintenance

• Cleaning: Keep the board clean and free from dust and debris. Use a soft, dry cloth for cleaning. Avoid using liquids or abrasive cleaners.
• Environmental Conditions: Operate the module within its specified temperature and humidity ranges. Avoid exposure to extreme temperatures, moisture, or corrosive environments.
• Connections: Periodically check all power and network connections to ensure they are secure.
• Firmware Updates: Check the manufacturer's website for any available firmware updates to ensure optimal performance and security.

7. Troubleshooting

• No Power Indicator:
  • Ensure the 5V DC power supply is correctly connected and functioning.
  • Verify the power adapter is plugged into a live outlet.
• No Network Connection:
  • Check the Ethernet cable connection to both the module and the router/switch.
  • Verify that your network router/switch is operational.
  • Confirm network settings (IP address, subnet mask, gateway) are correctly configured for the module.
• Relay Not Switching:
  • Ensure the module has power and a stable network connection.
  • Verify that the control commands sent to the module are correct and in the expected format.
  • Check the wiring of the external device to the relay terminal block.
  • Confirm the external device itself is functioning correctly.
• Module Unresponsive:
  • Perform a power cycle (disconnect and reconnect power).
  • If issues persist, consider resetting the module to factory defaults (refer to specific software instructions for this procedure).
