The 220V Single-Channel Wireless Receiver Board is a ready-to-use wireless control solution designed for direct integration into high-voltage AC circuits. This module serves as a bridge between a wireless remote and a high-power device, allowing you to control lighting, motors, pumps, or other 220V AC equipment without complex wiring or programming.
The system includes a compact receiver board capable of handling up to 220V AC, paired with a stylish walnut-finished remote controller. The 433MHz wireless frequency ensures stable signal penetration through walls and obstacles, providing reliable control for home automation, industrial equipment, and DIY projects. Whether you are retrofitting existing lighting systems or building automated machinery, this module offers a simple, effective solution.
Key Features
-
Direct 220V AC Power Supply: The receiver is designed to be powered directly by mains voltage (90V–250V AC), eliminating the need for an external DC power adapter.
-
High-Power Relay Output: Features a built-in relay capable of switching loads up to 10A at 220V AC, suitable for controlling lights, fans, pumps, motors, and other household or industrial appliances.
-
433MHz Wireless Technology: Operates on the 433MHz frequency band, which offers better penetration through walls and longer range compared to 2.4GHz alternatives, typically achieving 30–50 meters of effective control indoors.
-
Learning Mode for Code Pairing: The receiver supports “learning mode,” allowing you to pair multiple remote buttons or replace lost remotes without any specialized programming tools.
-
Multiple Control Modes: Supports both toggle mode (press button once to turn on, press again to turn off) and momentary mode (device stays on only while button is pressed), configurable via button on the receiver.
-
Stylish Walnut Remote Controller: The transmitter is housed in a sleek, natural walnut wood casing, providing a premium look and feel suitable for home decor.
-
Easy Installation: The receiver board features screw terminals for line-in, neutral, and load connections, making it simple to wire into existing electrical boxes.
-
Status Indicator: An onboard LED provides clear visual feedback for power status and relay activation.

Usage Guide
Wiring Instructions
-
Power Off: Always ensure the mains power is turned off before wiring.
-
Connect Power: Connect the Live (L) and Neutral (N) wires from the AC source to the corresponding terminals on the receiver board.
-
Connect Load: Connect the live wire of your device (lamp, fan, etc.) to the “LOAD” terminal. Connect the neutral wire of your device directly to the mains neutral.
-
Check Connections: Double-check all connections are secure before applying power.
-
Power On: Restore mains power. The status LED should illuminate, indicating the receiver is ready.
Pairing the Remote (Learning Mode)
The receiver can learn the code from the remote control through a simple process:
-
Enter Learning Mode: Press and hold the learning button on the receiver for about 3 seconds until the status LED starts blinking rapidly.
-
Transmit Signal: Press the button on the walnut remote controller while the LED is blinking.
-
Confirmation: The LED will stop blinking and stay on (or blink slowly) to confirm successful learning.
Note: The receiver can typically store multiple remote codes, allowing for control from several transmitters.
Switching Control Modes
The receiver supports two operating modes:
-
Toggle Mode (Latch Mode): Press the remote button once to turn the load ON; press it again to turn it OFF. This is ideal for lighting and general switching applications.
-
Momentary Mode (Jog Mode): The load is ON only while you hold down the remote button. When you release the button, the load turns OFF. This is ideal for motor control, garage doors, or doorbells.
To switch modes, press the “Mode” button on the receiver board.
Clearing All Learned Codes
To reset the receiver and clear all previously paired remotes:
-
Press and hold the learning button.
-
Hold the button until the LED indicator turns off.
-
Release the button. All codes are now cleared.
Q: What is the maximum load this relay can handle?
The internal relay is rated for 10A at 220V AC. For resistive loads like incandescent lights or heaters, this equates to up to 2200W. For inductive loads (motors, pumps), it is recommended to derate the load to 5A-8A to account for startup surges.
Q: What is the effective range of the remote?
In open outdoor space, the range can reach up to 100 meters. Indoors, through walls and floors, the effective range is typically 30–50 meters, depending on building materials (concrete/metal reduce range).
Q: Is this system compatible with smart home assistants like Alexa or Google Home?
This is a standalone RF remote system and does not have built-in Wi-Fi or smart home integration. However, you can pair it with a universal RF bridge or smart hub that supports 433MHz to enable app or voice control.
Q: The remote stopped working after I changed the battery. What should I do?
Sometimes the battery removal can reset the remote’s code transmission. You need to re-pair the remote with the receiver by entering the learning mode again.
Q: Can I use multiple remotes to control the same receiver?
Yes. The receiver can learn codes from up to 20 different remotes (or buttons), allowing multiple family members or workers to control the same device.
Q: The receiver clicks but the lamp/device doesn't turn on. What's wrong?
This indicates the relay is activating but the load circuit is not complete. Check the wiring:
-
Ensure the device’s neutral wire is connected directly to the mains neutral.
-
Ensure the device’s live wire is connected to the receiver’s “LOAD” terminal.
-
Verify the device itself is functional.
Q: How do I set the receiver to "Momentary" (hold to operate) mode?
Press the “Mode” button on the receiver board. The status LED usually changes its blink pattern to indicate the mode. Cycle through until the desired behavior is achieved.
Q: Can I install this receiver inside a standard electrical wall box?
Yes, the compact PCB is designed to fit inside most standard electrical junction boxes. Ensure proper insulation and clearance to avoid short circuits with the 220V terminals.
Q: Does the receiver get hot?
The receiver may become slightly warm during normal operation, especially under high loads (approaching 10A). Ensure it is installed in a well-ventilated area away from flammable materials.
Q: Can I use this to control a 12V DC device?
While the receiver is designed for 220V AC, you can use it to switch a 12V DC circuit by using an external 12V power supply. Connect the AC power to the receiver as normal, and connect the 12V load to the “LOAD” and “N” terminals (ensuring the DC load is within the relay’s 10A rating).
