KR2201 433Mhz Wireless Single Channel Relay

The 433 MHz wireless single-channel relay is a switch that, when connected to the city power, is a relay with a power cut-off and connection, through which any type of electrical device (air conditioner, lamp, motor, etc.) with any voltage can be turned on and off. This single-channel 220 volt AC relay has the ability to operate in 3 ways (swing, cut-off, momentary) and at a distance of 50 meters, it sets the operation of another device in two states: off or on.

This single-channel wireless 433Mhz relay is the KR2201 model, which easily cuts and connects part of the circuit.

Erasing and coding:

Erasing function: By pressing the "KEY" learning button 8 times, after the LED indicator turns off, all the data of the remote control codes in the memory are erased. When the LED indicator flashes five times and then turns off, the erasing process is complete.

Coding function: By pressing the learning button "KEY", the LED indicator lights up, indicating that the microprocessor has entered the learning and coding mode. By pressing the corresponding button on the remote control, the LED indicator flashes three times and then turns off, indicating the success of the coding. This remote control switch can store up to 16 different remotes. (This model has single-button coding, and the program automatically allocates data bits.)

Coding test: After the coding is successful, by pressing the corresponding button on the remote control, the corresponding relay will operate and perform the desired function.
