Einrichtung und Verkabelung
Produkt überview

This image displays the Yitouniu Zigbee 2-Channel Smart Relay Switch Module. It shows the input terminals for power, the mode switch button, manual operation buttons for relays R1 and R2, and the output terminals (NO, COM, NC) for connecting appliances. The device is housed in a white casing with ventilation slots.

Dieses Bild liefert eine detaillierte Ansicht. view of the module's internal circuit board with key components labeled. It highlights the 'Model switch button', 'Manual switch' buttons, 'Network indicator' (red light), 'RF Pairing indicator' (blue light), and the 'Relay' components. Input terminals for DC 7-32V and USB 5V are shown, along with output terminals (NC, COM, NO) for connecting external devices.
Stromversorgungsoptionen
The module can be powered via two methods:
- DC/AC 7-32V: Connect your power source to the 'Input DC/AC 7-32V' terminals.
- USB-5V: Connect a 5V USB power adapter to the micro USB port.
Wiring Diagrams for Operating Modes
The module supports three operating modes: Inching (Momentary), Self-Lock, and Interlock. The wiring for connected appliances will vary based on the chosen mode and application.

This image illustrates typical wiring configurations. The top diagram shows an Interlock-Modus connection for a motor, where the module controls the motor's direction (e.g., upload/download). The middle diagram shows a Three-Wire Motor Connection in Interlock Mode, detailing how to connect a 220V motor for directional control. The bottom diagram demonstrates an Appliance Connection in Self-lock Mode for AC 220V lights, where each relay acts as an independent on/off switch.

This diagram specifically shows a Self-locking mode wiring example for a single light bulb. The input power is DC 7-32V, and the light bulb is connected to the relay's output terminals, allowing it to be toggled on or off independently.
Pairing with Zigbee Gateway
This module requires a Zigbee gateway (hub) for smart control. Ensure your Zigbee gateway is set up and ready for device pairing.

This image emphasizes that a Tuya Zigbee Hub is required to connect and manage multiple Zigbee smart devices, including this relay module, within your smart home ecosystem.
- Laden Sie die App herunter: Install the Tuya Smart or Smart Life app on your smartphone.
- Mit Hub verbinden: Ensure your Zigbee gateway is connected to your home network.
- Kopplungsmodus aktivieren: Power on the Yitouniu module. Press and hold the 'Mode Switch' button for approximately 5 seconds until the network indicator light blinks, indicating it's in pairing mode.
- Gerät in der App hinzufügen: Open the Tuya Smart or Smart Life app, navigate to your Zigbee gateway, and select 'Add Sub Device' or 'Suchen nach devices'. The app should detect the module.
- Kopplung bestätigen: Follow the on-screen prompts to complete the pairing process. Once successfully paired, the network indicator light will stop blinking.

This visual guide outlines the quick setup process: 1. Download the Alexa/SmartThings app. 2. Connect to your Alexa/SmartThings hub. 3. The Yitouniu 2CH Smart Switch module. 4. Add devices within the app.
Betriebsarten
The Yitouniu Smart Relay Switch Module offers three distinct operating modes:
- Self-Lock Mode: In this mode, each relay acts as a standard on/off switch. A single command (or button press) toggles the relay's state (ON to OFF, or OFF to ON). This is ideal for controlling lights or other appliances that require a persistent state.
- Inching (Momentary) Mode: When activated, the relay turns ON for a preset duration (e.g., 1 to 3600 seconds) and then automatically turns OFF. This mode is commonly used for applications like garage door openers, where a brief pulse is needed to trigger an action.
- Verriegelungsmodus: This mode ensures that only one relay can be ON at any given time. If one relay is activated, any other active relay will automatically turn OFF. This is useful for controlling devices with mutually exclusive states, such as motor direction (forward/reverse) or fan speed selection.
You can switch between these modes using the 'Mode Switch' button on the device or through the connected smart home app, depending on the specific gateway and app features.
Intelligente Steuerungsfunktionen
Sprachsteuerung
The module is compatible with Amazon Alexa and Google Assistant, allowing for hands-free voice control of connected appliances. Once integrated with your Zigbee gateway and linked to your voice assistant, you can use commands like:
- "Alexa, turn on the garage light."
- "Hey Google, schalte den Ventilator aus."

This image highlights key features including Zigbee 3.0 compatibility, voice control integration with smart speakers, app control via a smartphone, and the wide transmission range offered by Zigbee networks.
App-Steuerung und Zeitplanung
Manage your connected appliances remotely using the Tuya Smart or Smart Life app. Features include:
- Fernbedienung EIN/AUS: Control devices from anywhere.
- Status-Verfolgung: View the real-time status of your devices in the app.
- Timer: Set countdown, scheduled, or cycle timers for automated operation.
- Intelligente Szenen: Create custom automation rules based on conditions like departure/home mode, temperature, humidity, or other Zigbee product interactions.
