Frequently Asked Questions
Q: What voltage ranges does this RF 433MHz wireless relay switch support?
A: The receiver supports a wide range of voltages — AC 75V to 240V and DC 9V to 72V — making it compatible with 12V, 24V, 48V, 72V, 110V, and 220V systems. This makes the switch highly versatile for a variety of residential and industrial applications including LED lighting, water pumps, and electric motors.
Q: What is the maximum load current for this relay switch?
A: While the relay is rated for a peak current of 30A, the rated continuous load current should not exceed 15A at 240VAC or 110VAC. Always ensure your application's steady-state current stays under 15A to maintain safe and reliable operation.
Q: How far can the wireless remote control reach?
A: In an open area with no obstructions, the transmitter can communicate with the receiver from up to 100 meters (approximately 330 feet). Range may be reduced in environments with walls, metal structures, or significant RF interference.
Q: Can I use multiple remote controls or program additional remotes to this receiver?
A: Yes. The receiver uses a learning code system, which allows you to pair additional compatible 433MHz remote controls (or optional 315MHz controllers) to the same receiver. Simply use the learning button to add new remotes, and hold it for 8 seconds to clear all stored codes if needed.
