4-Channel RF Wireless Relay Remote Control Transmitter and Receiver Module

The 4-Channel RF Wireless Relay Remote Control gives you four independently switchable relay outputs controlled wirelessly from a handheld transmitter. RF (Radio Frequency) means the control signal travels through the air without any wires between the remote and the receiver board. The 4-Channel RF Wireless module operates at 315 or 433 MHz, which are the two most common frequencies for short-range remote control in India and worldwide. Each relay channel switches on or off separately, so you can control four different appliances or circuits from one remote.

The 4 channel rf module relay board switches up to 10A of current per channel at 12V DC supply. One non-obvious detail — 10A is the relay contact rating, not the safe continuous current for the PCB tracks. The PCB copper traces on most relay boards are rated lower. For loads above 5A continuous, always add external thick wires directly across the relay terminals rather than relying on the board trace. The honest limitation is communication distance — rated at 5 meters only, which suits indoor room-to-room use but not cross-building or outdoor control.

The 4 channel rf remote control module connects to Arduino and other microcontrollers through its relay output pins for automated control. Hobbyists and electrical engineering students for switching projects. power the receiver board from a 12V DC adapter, press any button on the transmitter, and watch the matching relay click. StemVolt ensures quick dispatch and dependable delivery across India.
