3.3 Sambungan Jaringan

Connect the module to your network using a standard Ethernet cable via the RJ45 port. If using PoE, this connection will also provide power.

3.4 Relay Wiring

The module provides 30 independent relay channels. Each channel has Normally Open (NO) and Normally Closed (NC) contacts, along with a Common (COM) terminal. Refer to the diagrams below for typical wiring configurations.

• AC Device Connection: For AC loads (e.g., 220V AC), connect the AC power source to the COM terminal and the load to either the NO or NC terminal, depending on the desired default state.
• Sambungan Alat DC: For DC loads (e.g., 30V DC), connect the DC power source to the COM terminal and the load to either the NO or NC terminal.

Ensure all wiring is done with the power off to prevent electrical shock or damage to the module and connected devices. The relay contacts are rated for 10A 250VAC / 10A 30VDC.

6. Cara ngungkulan

If you encounter issues with your Waveshare 30-Ch Ethernet Relay Module, consider the following troubleshooting steps:

• Henteu aya kakuatan: Check the power supply connection (DC 7-36V or PoE). Ensure the power source is active and providing the correct voltage. Verify the PWR LED is illuminated.
• Henteu aya sambungan jaringan: Check the Ethernet cable and ensure it is securely connected to both the module and the network switch/router. Verify the Link and ACT LEDs are indicating network activity. Ensure your network settings (IP address, subnet mask, gateway) are correctly configured, especially if not using DHCP.
• Relay Teu Ngaréspon: Verify that the module is powered and connected to the network. Check the control commands being sent (Modbus RTU/TCP) for correctness. Ensure the relay status LEDs (CH1-CH30) are responding as expected. Confirm that the load connected to the relay is within its specified contact rating.
• Operasi intermittent: This could be due to unstable power, loose connections, or network issues. Re-check all physical connections and power stability.
• Module Not Accessible via Web/Software: Ensure the module's IP address is correct and accessible from your network. Temporarily disable any firewalls on your computer that might block communication.
