2.  Short introduction to relay receiver working modes

The following introduction will describe how momentary, latching and toggle working using example of typical two channel receiver. The transmitter button A controls channel 1 while transmitter button B controls channel 2.

1. Toggle - Press A > Channel 1 ON and remains ON, Press A again > Channel 1 OFF

2. Momentary - Press and hold A > Channel 1 ON, Release A > Channel 1 OFF

3. Latching - Press A > Channel 1 ON and remains ON while Channel 2 OFF, Press B > Channel 2 ON and remains ON while Channel 1 OFF

[1]. RF Sensitivity: RF Sensitivity depends on the receiver module. We use Super-regenerative receiver module (KL-S3) generally as it is worth and low battery consumption. If you want high sensitivity, we can change super heterodyne module for you.


4. RF Remote Control Relay Looking for Matching Transmitter and Accessories?

Compatible with all Shenzhen Kelvin RF Remote Control Transmitters

Our RF Remote Control Transmitters provide an easy out of the box function to control most universal devices wirelessly, and is best performed when paired with our receiver modules, while Long Range RF Remote Control Transmitters can extend the transmitting distance up to 2000 metres.

5. RF Remote Control Relay Applications

Widely used in home electric control, smart house, etc. People can use it very easily to control light, LED and so on.

6. RF Remote Control Relay Antenna Application Guide

For whip antenna, it is best to use the antenna of 1/4 wavelength, for antenna has a great impact on reception effect of the module, normally using 50Ω single core cable. For frequency 315MHz, the length of antenna is about 23cm and for 433MHz, it is about 17cm.

The position of antenna also affects the reception effect of the module. During installation, the antenna should be extended as much as possible, away from the shield enclosure and placed high above ground.
