5. Setup and Installation
5.1 Powering the Module
The module can be powered by either DC 7-32V via the screw terminals or DC 5V via the Type-C USB port. Choose the appropriate power source for your application.
- Using DC 7-32V: Connect your DC 7-32V power supply to the screw terminals labeled 'Input Power DC 7-32V'. Ensure correct polarity (+ and -).
- Using DC 5V (Type-C): Connect a standard 5V USB power adapter (e.g., phone charger) to the Type-C port.
5.2 Wiring the Load
The relay has three terminals: Common (COM), Normally Closed (NC), and Normally Open (NO). The wiring configuration depends on whether you want the connected device to be ON or OFF when the relay is de-energized.
- Normally Open (NO) Configuration: For devices that should turn ON when the relay is activated. Connect one side of your load (e.g., light bulb) to the power source, and the other side to the NO terminal. Connect the COM terminal to the other side of the power source.
- Normally Closed (NC) Configuration: For devices that should turn OFF when the relay is activated. Connect one side of your load to the power source, and the other side to the NC terminal. Connect the COM terminal to the other side of the power source.
5.3 Network Pairing (WiFi)
To control the module via a mobile application, it must be paired with your WiFi network.
- Download App: Download the compatible smart home application (e.g., Tuya Smart, Smart Life) from your device's app store.
- Power On: Apply power to the module. The Network Indicator LED will start blinking, indicating it's ready for pairing. If not, press and hold the 'Network Pairing Button' for 5-7 seconds until it blinks rapidly.
- Add Device: Open the app, register or log in, and select 'Add Device' or the '+' icon. Follow the in-app instructions to add a 'Switch' or 'Relay' device.
- Connect to WiFi: Enter your WiFi network name (SSID) and password when prompted. Ensure your phone is connected to a 2.4GHz WiFi network.
- Confirmation: Once connected, the Network Indicator LED will stop blinking and remain solid, and the device will appear in your app.
6. Operating Modes
The Smart Relay Module supports three primary operating modes, configurable via the mobile application:
- Jog Mode (Momentary): In this mode, the relay activates only while the control button (physical or in-app) is pressed. Once released, the relay deactivates. This is suitable for applications requiring a brief pulse of power.
- Inching Mode (Timed Momentary): Similar to Jog mode, but the relay activates for a preset duration (e.g., 0.5 seconds to 3600 seconds) after the button is pressed, then automatically deactivates. The duration can be configured in the app.
- Self-Locking Mode (Toggle): In this mode, each press of the control button toggles the relay's state. One press turns it ON, the next press turns it OFF. This is suitable for standard ON/OFF control of lights or appliances.
6.1 Manual Operation
The 'Manual On/Off Button' on the module allows for direct control of the relay without the app or network connection. Each press of this button will toggle the relay's state (ON/OFF).
7. Maintenance
- Keep the module clean and free from dust. Use a dry, soft cloth for cleaning.
- Ensure the module is installed in a well-ventilated area to prevent overheating.
- Avoid exposing the module to direct sunlight or extreme temperatures.
- Regularly check wiring connections to ensure they are secure.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Module not powering on | No power supply; Incorrect voltage; Incorrect polarity | Check power connections; Ensure voltage is within 7-32V DC or 5V DC (Type-C); Verify polarity. |
| Network Indicator not blinking for pairing | Already paired; Not in pairing mode | Check app for existing device; Press and hold 'Network Pairing Button' for 5-7 seconds to enter pairing mode. |
| Cannot connect to WiFi | Incorrect WiFi password; 5GHz WiFi network; Weak signal | Verify WiFi password; Ensure your router is broadcasting a 2.4GHz network; Move module closer to router. |
| Relay not activating/deactivating | Incorrect wiring of load; Faulty relay; Incorrect mode setting | Review load wiring (COM, NO, NC); Test relay manually with 'Manual On/Off Button'; Check mode setting in app. |
| App control unresponsive | No internet connection; Module offline; App issue | Check your internet connection; Verify module's network status (solid LED); Restart app or phone. |
