433MHz 12V 4 Channel Relay Module Wireless Remote Control Switch without Battery
The 433MHz 12V 4 Channel RF Remote Control Kit is a high-performance, compact wireless relay switch system designed to control electrical devices remotely. Operating on the 433MHz frequency, this relay module provides robust connectivity through RF (radio frequency) communication, making it ideal for controlling lights, fans, motors, door locks, and security systems.
This kit comes with a 4-channel relay module and a 4-button RF remote control (battery not included). It supports multiple working modes, including self-locking, non-locking, and interlocking, configurable using the onboard jumpers. Each channel can handle up to 10A at 12VDC or 5A at 220VAC, making it suitable for medium to high-power applications.
The board features a working range of up to 50 meters in open space and 25 meters indoors, with a DC 12V input voltage. The simple design and easy learning process make pairing with the remote seamless.
