RF RECEIVER 4 CHANNEL RELAY REMOTE CONTROL

Product Description

The 4-Channel RF Relay Receiver Module is a wireless remote control switching system designed to control up to four independent electrical loads using an RF transmitter (commonly 433 MHz). It is widely used in home automation, industrial control panels, gate systems, lighting control, pumps, motors, and security systems.

The receiver converts wireless RF signals into relay ON/OFF outputs, allowing safe isolation between low-voltage control and high-power loads.
