12V 4CH Channel 315Mhz RF Wireless Remote Control

The 12V 4-Channel 315MHz RF Wireless Remote Control System is a professional-grade wireless control kit designed to bring reliable, long-range remote operation to a wide variety of electrical and electronic devices. The set includes a 4-channel relay receiver and a 4-button RF transmitter, working together at 315MHz to deliver stable, interference-resistant communication at distances of up to 200 meters in open environments.

The receiver module is built around four onboard relays, each independently controlled by one button on the transmitter. This allows the user to switch up to four separate devices, control motor direction (forward/reverse), or implement complex on/off sequences. The system is built using high-sensitivity superheterodyne receiver technology (greater than -105 dBm), ensuring excellent performance even in environments with significant RF noise.

A standout feature of this kit is its learning code function, which allows the receiver to memorize and pair with up to 12 different remote controls. The system is compatible with all major fixed-code and learning-code chips, including PT2262, PT2260, EV1527, and HT2240, giving it broad cross-compatibility with existing wireless devices and remote controls. Pairing is straightforward: simply press the learning button on the receiver, then press any button on the transmitter, and the indicator LED confirms a successful pairing.

The receiver supports three configurable output modes, easily selectable via onboard jumpers:

• Self-Lock (Toggle): Press once to turn ON, press again to turn OFF.
• Jog (Momentary): Output is active only while the button is held.
• Inter-Lock: One button turns ON, another turns OFF.

Operating from a standard 12V DC power supply with less than 6 mA quiescent current, the receiver is energy-efficient and well-suited for continuous operation in automation, security, and access-control systems. The relay outputs are rated for up to 10A maximum load, making the system capable of handling both low-voltage signal switching and medium-power AC/DC loads.
