433MHz 12V 2 Channel Relay Module Wireless with RF Remote Control Switch with Battery

This 2-channel multifunction RF receiving controller is for sending open signal and close signal to 2 relays. It can be used to turn on/ off, connect/disconnect or implement other specific controlling program on the controlled devices or motor. Typical applications for relays include fields of electronically operated gate, windows, lifting appliance, switch, lifter, industrial control, security industry etc.

The RF controller has the advantages of high confidentiality, high stability, low power, and use expediently; no need for traditional connecting wire or dial fixing code switch, all you need to do is learn to match the code of the remote controller with the receiving controller.

Output mode of 12V 2 Channel Relay Module Wireless:

The output mode of this controller is usually divided into non-lock, interlock, self-locking, non-lock and self-lock coexisting. (Note that you can switch the mode directly without deenergization)

1.Self-lock: connect JP1 and JP2

Press key A, the corresponding relay will be actuated and keeps closed. Press A again, the relay A is disconnected. Press B, the corresponding relay is actuated and keeps closed, press B again, relay B is disconnected.

2.Non- lock: disconnect JP1 and JP2.

Press A, the corresponding relay is actuated and it is disconnected right after you release the key A. relay B works in the same way.

3.Interlock: connect JP1, disconnect JP2

Press A, the corresponding relay will be actuated and keeps closed. When you press B, relay A will be disconnected and relay B is actuated simultaneously and keeps closed.

4.Non-lock and self-lock coexisting: disconnect JP1, connect JP2.

One relay corresponding to the remote controller is in self-lock mode, another is in non-lock mode.

Learning method of 12V 2 Channel Relay Module Wireless：

1.You will enter learning state after the led indicator of the receiver blinks once. Press any key on the controller after the led indicator blinks four times, it has received the signal, and the learning is successful. Press the learned key; you can control the corresponding relay now. Learn and configure of the two relays respectively: connect JP 1, you can press a key to learn one of the relays, disconnect JP1, you can press another key to learn another relay.

After the learning, the remote can work. You can choose one key to learn and control alone.

2.If a learned remote controller gets lost, you should clear the stored information in the receiver controller. Thus, the lost one cannot controller the receiver any more. A new one must be learned according to the above method.
