Technical Specifications

Remote Control Transmitter

Receiver Board

⚠️ Important: Although the relay is labelled 30A 240VAC, the 30A rating is for peak load only. Your continuous rated load current must remain below 15A to ensure safe, reliable operation.

6 Learning Modes — Full Programming Flexibility

Press the Learning Button on the receiver the corresponding number of times to set your preferred mode. The LED will confirm each step:

1. Momentary — Press 1 time; relay activates only while button is held
2. Toggle — Press 2 times; each button press switches relay ON or OFF
3. Latched — Press 3 times; relay stays ON after press, OFF after next press
4. Delay 5s — Press 4 times; relay turns OFF automatically after 5 seconds
5. Delay 10s — Press 5 times; relay turns OFF automatically after 10 seconds
6. Delay 15s — Press 6 times; relay turns OFF automatically after 15 seconds

To clear all stored codes: Hold the Learning Button for 8 seconds until the LED flashes 3 times then goes off.

Frequently Asked Questions

Q: What is the true maximum continuous current this 433MHz wireless relay switch can handle?

A: While the relay module is marked "30A 240VAC," the safe continuous rated current is 15A. The 30A figure refers to peak or inrush current only. Always ensure your load (pump, motor, LED system, etc.) draws less than 15A continuously to protect the relay and prevent overheating.

Q: Can I use this wireless remote switch with both AC and DC power systems?

A: Yes! The receiver board supports AC 75V–240V (covering most global mains voltages) as well as DC 9V–72V, making it compatible with battery systems, solar setups, automotive, and industrial DC applications. Simply connect the appropriate supply to the receiver's input terminals.

Q: How do I pair (learn) a new remote transmitter to the 433MHz receiver?

A: Press the Learning Button once to enter Momentary mode (or 2–6 times for other modes), wait for the LED to flash the corresponding number of times, then press your transmitter button. When the LED flashes 3 times, the transmitter is successfully paired. You can pair multiple transmitters to the same receiver using this method.

Q: What is the transmission range of this wireless remote control switch?

A: In open-field conditions, the 433MHz transmitter has a range of approximately 100 metres (about 330 feet). Range may be reduced indoors or near metal structures, walls, or other RF interference sources.
