Smart 2Ch Relay Switch 10A + Shell | RF433Mhz + BT | DC 7‑32V Input

A compact smart relay controller with 2 independent channels that lets you switch electrical loads using Wi-Fi (Tuya SmartLife app), Bluetooth, or RF 433 MHz remote control (remote sold separately). Designed for DIY automation projects and smart home installations.

This DC-powered option accepts 7—32 V DC supply, ideal for battery systems, solar setups, DC appliance switching, and low-voltage automation tasks.

Key Features

Power & Connectivity

• Input Voltage (DC version): 7—32 V DC via terminal block — select this option when ordering.
• Micro-USB 5 V DC input option also available for powering logic circuits.
• Wi-Fi: Works on IEEE 802.11 b/g/n 2.4 GHz networks for remote control via the Tuya/SmartLife app.
• Bluetooth Low Energy: Local control without internet.
• RF 433 MHz support: Use with compatible remote controls (sold separately) for manual switching.

Smart Control

• Control devices from your smartphone via the Tuya SmartLife app.
• Compatible with Amazon Alexa and Google Home voice assistants.
• Create schedules, timers, scenes, and automation routines.
• Manual mode buttons on the board for direct switching.

Relay Outputs

• 2 independent relay channels — each channel can switch a load.
• Dry contact relays: switch external circuits without injecting power (relay contacts only).
• Max switching load: AC up to 250 V, 10 A (for AC loads). DC up to 30 V, 10 A (for DC loads)

Mode Options

• Self-locking (stay ON/OFF)
• Inching (pulse/temporary ON) Selectable via board button or app configuration.

Physical

• Compact PCB with protective shell
• LED indicators for channel status
• Operating range: —10 °C to +60 °C, 5—95 % humidity.

Typical Uses

• Smart lighting control
• Automate DC devices (12 V/24 V systems)
• Gate or garage switches
• Motor controls with external drivers
• Timed or app-controlled appliances
• Solar/battery-powered smart automation

Because the board presents dry contact outputs, you can use it safely with external loads and power sources appropriate to the load (e.g., separate DC battery for a motor) without passing supply through the board.

What's in the Box

• 1 × Smart 2Ch Relay Switch DC-powered version
• 1 × Protective Shell
• 1 × Quick Manual (RF remote not included)

Wiring & Installation Notes

• Power: Connect a 7—32 V DC supply to the DC input terminals to power the logic and relays.
• Outputs: Use the COM/NO/NC terminals for each channel as dry contacts — the board does not supply load power itself. You must provide appropriate external power (battery or DC supply) to your device.
• Safety: Always disconnect power before wiring. This board does not include mains isolation, so use caution when switching high voltages.

Tips & Compatibility

• Works with Android & iOS through the Tuya SmartLife app.
• Ensure your Wi-Fi router broadcasts at 2.4 GHz (not 5 GHz).
• Ideal for DC systems like 12 V or 24 V common in solar, automotive, and workshop applications.
