Two Single Channel Transmitters Remote Control Two Relays on One Receiver

Question from customer:

I need a 2 channel receiver with 2 remotes 1 channel. One remote control activates the channel A receiver on the receiver and another remote to turn on the channel B on the receiver. Is it possible with the CWB-1 model? And which receiver would like to recommend?


We recommend 2 channel 12V multi-mode receiver (S2U-DC12) and two waterproof wireless 50m remotes (CWB-1). We set configured code for them so that they can work together. The receiver is 12V activated and has two relays. When it works with that transmitter, its transmission distance can reach 50m in the open air. There is only one button on each transmitter.

It can control lights, motors, fans, electrically operated doors / locks / windows / blinds / cars or other appliances with AC110~240V or DC0~28V. You can turn on/off the receiver with transmitter (remote control) from any place within a reliable distance; the wireless RF signal can pass through walls, floors, doors and other obstacles.


We will take a dc lamp wiring method as an example.

A,B terminals is normally closed. B,C terminals is normally open.

Wire two lamps to B&C terminals of each relay. Do as following picture shown.
