Otcboimo Smart WiFi Wireless Relay Switch Module (4CH 7-32V) User Manual

1. ഉൽപ്പന്നം കഴിഞ്ഞുview

The Otcboimo Smart WiFi Wireless Relay Switch Module (Model TYWB4CH-D1) is a 4-channel smart relay designed for remote control of home appliances. It supports both AC/DC 7-32V and USB 5V power input, offering flexible integration into various setups. This module features dry contact/passive output, meaning it does not supply voltage to the connected appliance directly; an external power source is required for the appliance. It is compatible with Tuya/Smart Life applications, Amazon Alexa, and Google Home for voice and remote control.

The module supports three working modes: Self-locking, Interlocking, and Inching, catering to diverse automation needs. It also includes a timing function for scheduled operations and RF433MHz control capability.

4. Operating Modes and Control

4.1 Self-Locking Mode

In Self-locking mode, each relay acts as an independent switch. Pressing the button (physical or in-app) turns the relay ON, and pressing it again turns it OFF. This mode is suitable for controlling individual lights or appliances.

Image 4.1: Wiring diagram illustrating Self-Locking Mode. Input can be USB 5V or DC/AC 7-32V. The output circuit is shown controlling four light bulbs, with each relay acting independently. The circuit within the relay supports AC 0-250V 10A / DC 0-30V 10A.

4.2 Interlocking Mode

In Interlocking mode, only one relay can be ON at a time. When one relay is activated, any previously active relay in the group will automatically turn OFF. This mode is ideal for applications where only one state should be active, such as controlling a motor's forward/reverse direction.

Setting Interlocking Mode via App:

1. Open the Tuya/Smart Life app and navigate to your device.
2. Tap on the "Setting" icon (usually a gear icon) at the bottom of the screen.
3. Select "Interlock set" from the options.
4. Tap "Add" to create a new interlock group.
5. Select the switches (relays) you want to include in the interlock group (e.g., Switch 1, Switch 2, Switch 3, Switch 4).
6. Tap "Save" to apply the settings.

4.3 Inching Mode (Momentary)

In Inching mode, the relay turns ON for a set duration (e.g., 0.5 to 3600 seconds) and then automatically turns OFF. This is useful for momentary actions like opening a gate, triggering a garage door, or pulsing a signal.

Setting Inching Mode via App:

1. Open the Tuya/Smart Life app and navigate to your device.
2. Tap on the "Timer" icon at the bottom of the screen.
3. Select the specific switch (relay) you want to configure.
4. Tap on the "Inching" tab (often represented by a clock icon).
5. Enable the inching function and set the desired duration (e.g., 03 seconds).

5. വയറിംഗ് ഡയഗ്രമുകൾ

The Otcboimo Smart WiFi Wireless Relay Switch Module provides dry contact outputs. This means the relay acts as a switch that opens or closes a circuit, but it does not provide power to the connected device. You must supply power to the appliance separately.

Refer to the specific mode diagrams (Self-Locking, Interlocking, Inching) in Section 4 for detailed wiring examples. Always ensure power is disconnected before making any wiring changes.

6. പരിപാലനം

• വൃത്തിയാക്കൽ: Use a soft, dry cloth to clean the module. Do not use liquid cleaners or aerosols.
• ഫേംവെയർ അപ്‌ഡേറ്റുകൾ: Periodically check the Tuya/Smart Life app for available firmware updates to ensure optimal performance and security.
• പരിസ്ഥിതി സംരക്ഷണം: Keep the module away from water, excessive heat, and direct sunlight.

7. പ്രശ്‌നപരിഹാരം

• മൊഡ്യൂൾ ഓണാക്കുന്നില്ല: Verify the power supply connection (USB 5V or AC/DC 7-32V) and ensure the power source is active.
• ആപ്പുമായി ജോടിയാക്കാൻ കഴിയുന്നില്ല:
  • നിങ്ങളുടെ ഫോൺ 2.4GHz വൈഫൈ നെറ്റ്‌വർക്കിലേക്ക് കണക്റ്റുചെയ്‌തിട്ടുണ്ടെന്ന് ഉറപ്പാക്കുക.
  • Confirm the module's Wi-Fi indicator is blinking rapidly (pairing mode). If not, press and hold the reset button.
  • Check Wi-Fi signal strength. The module should be within close proximity to your router.
  • നിങ്ങളുടെ റൂട്ടർ പുനരാരംഭിച്ച് വീണ്ടും ജോടിയാക്കാൻ ശ്രമിക്കുക.
• Appliance Not Responding:
  • Check the wiring connections to the appliance and ensure they are secure.
  • Verify that the appliance has its own power supply and is functioning correctly.
  • Confirm the relay is switching ON/OFF in the app.
• ശബ്ദ നിയന്ത്രണം പ്രവർത്തിക്കുന്നില്ല:
  • Ensure the module is successfully linked to your Alexa or Google Home account via the Tuya/Smart Life app.
