4.1 Instrucciones de cableado

Nota importante de seguridad: All wiring should be performed by a qualified electrician or individual with electrical knowledge. Ensure power is disconnected before performing any wiring to prevent electric shock. The relay acts as a switch and does not provide voltage output; the power supply input (AC/DC) is solely for the module's operation.

Diagrama de cableado general

This diagram illustrates the connection points: Input for DC 7V~32V (or USB 5V), and output terminals NO (Normally Open), COM (Common), NC (Normally Closed) for connecting your load.

Wiring for Electric Motor Lock

4.2 Emparejamiento y conexión de aplicaciones

The LETLINK module uses the Tuya Smart Life app for remote control. Ensure your router supports 2.4GHz Wi-Fi, as the module does not support 5GHz. If your router has dual bands with the same SSID, temporarily disable the 5GHz band during pairing.

1. Descargar aplicación: Descarga la aplicación 'Smart Life' o 'Tuya Smart' desde la tienda de aplicaciones de tu dispositivo móvil (iOS o Android).
2. Encendido: Connect the relay module to its power supply (USB 5V or AC/DC 7-32V). The indicator light should flash quickly, indicating it's in quick pairing mode.
3. Abre la app: Launch the Smart Life app and ensure your phone is connected to the same 2.4GHz Wi-Fi network.
4. Agregar dispositivo: Tap the '+' icon in the top right corner of the app. The app should automatically discover the device via Bluetooth. Tap to add it.
5. Ingresar contraseña de Wi-Fi: Confirm your Wi-Fi network (2.4GHz) and enter the correct password.
6. Emparejamiento completo: Follow the on-screen prompts to complete the pairing process. The indicator light will stop flashing once connected.

Solución de problemas de emparejamiento: If the device does not enter quick pairing mode or fails to connect, long-press the pairing button on the module until the light flashes slowly. Then, try configuring it using the 'Compatible Mode' option in the app.

5. Instrucciones de funcionamiento

Modos de funcionamiento de 5.1

The module supports two primary operating modes:

• Inching (Momentary) Mode: In this mode, the relay will turn on for a set duration (e.g., 1 second) and then automatically turn off, or vice-versa. This is ideal for applications requiring a brief pulse, such as opening a garage door or activating an electric lock.
• Self-locking (Latching) Mode: In this mode, the relay acts as a traditional on/off switch. Once activated, it remains in that state until manually switched off. This is suitable for controlling lights or other appliances that need to stay on or off for extended periods.

5.2 Smart Life App Functions
