220V 433MHz Wireless Relay Module — Control two independent circuits from up to 70 metres away
Want to open your gate, start a pump, or switch off the lights without leaving your seat? With this 220V wireless relay module operating on the 433MHz frequency, you can do it all with a single press. The kit comes complete with a 2-channel receiver and two 2-button remote controls — ready to install and ready to use.
Note: The 70-metre range is measured in an open space without obstacles. The radio signal can penetrate walls, but the effective range will vary depending on your specific installation environment.
Why choose this model? (Key benefits):
- Two truly independent channels — control two separate circuits simultaneously with one remote in your hand.
- Range of up to 70 metres — the 433.92MHz signal reaches from your gate to your house, even through several walls.
- 2200W load capacity — powerful enough for gate motors, irrigation pumps, or outdoor LED strips.
- 3 operating modes — choose between Momentary, Toggle, or Latched modes to suit your specific application.
- 85–250V AC power supply — connects directly to standard mains power, no transformer or adapter required.
- -105 dBm reception sensitivity — picks up the signal even when the receiver is mounted inside a metal electrical enclosure.
Details and Performance
The relay contacts support 10A at 250V AC — providing a generous buffer for typical residential automation tasks. The module operates reliably between -10°C and +70°C, making it suitable for outdoor installations when housed in a protective box. It is frequently used in smart-home systems, automatic irrigation, garden lighting, and simple industrial controls where complex programmable controllers aren’t necessary.

Programming and Usage Instructions
Initial reset: Press the learning button on the receiver 8 times to clear all existing settings. It is recommended to perform a reset before first use.
Momentary Mode – the relay is active only while the remote button is held down:
- Press the learning button on the receiver once – the LED will turn off.
- Press button “A” on the remote – the LED will flash and then turn off.
- Press button “B” – the LED will confirm that learning is complete.
Toggle Mode – one press turns the relay on, the next press turns it off:
- Press the learning button twice – the LED will turn off.
- Press “A” then “B” on the remote to save the configuration.
Latched Mode – one button turns the relay on, the other turns it off (interlock):
- Press the learning button 3 times on the receiver.
- Press “A” and then “B” – the LED will confirm successful configuration.

Frequently Asked Questions
Can I use this module to control an automatic gate?
Yes, the module is compatible with gate motors that accept dry contact control or direct power, provided the load does not exceed 2200W.
Can the 2 channels control different devices independently?
Yes, each channel has its own relay and can be operated separately using buttons A and B on the remote, allowing you to control two distinct circuits.
Can I add more remotes?
Yes, the receiver allows you to pair multiple compatible 433.92 MHz remotes by following the same programming procedure described above.
What is the difference between Momentary, Toggle, and Latched modes?
In Momentary mode, the relay is active only while you hold the button; in Toggle mode, each press changes the state (ON/OFF); in Latched mode, one button turns the relay on, and the other turns it off.
Does the signal work through walls?
Yes, the 433 MHz radio signal passes through walls and common obstacles. The 70m maximum range is for open space; indoors, the effective distance may be shorter.
