Feature: 1. 1.433MHz 2-channel DC 12V receiver: designed to control various electronic devices through RF radio signals. It is perfect for remote control electric lights, electric doors, electric windows, rolling doors, garage doors and other remote control equipment. 2. 2. Adjustable working modes: instantaneous, switch, capture. All remote control switch kits support 433 MHz frequency. The learning code has high security due to low repetition frequency and re-learning mode. In addition, the receiver can add up to 25 remote controls. 3. 3. Practical and comfortable: small, stable and reliable, the maximum range in the open space is 100m. When the distance of the remote control cannot meet the requirements, please replace the battery. The distance of the remote control will be affected by the environment in which it is used. Do not place the receiver or remote control in a metal box or near metal objects. 4. 4. Easy to program: extremely easy to configure, the provided container is for indoor use, you can also take out the electronic card to insert it into the existing waterproof box, and connect the external antenna to the terminal provided on the circuit. 5. 5. The receiver is compatible with (1527) and (2262) types of fixed code remote controls. The receiver can be connected to any control panel and replace the existing receiver or operate in parallel with it. The contact of the output relay is normally open NA, the operation can be pulse type (monostable) or stepwise operation (bistable: on the first command, the relay closes the contact, on the second command, the relay Disconnect contacts, and so on). The memory of the radio control is taught by itself through the keys located on the side of the terminal board. 6. Working: 7. Moment: Press the remote control button, the relay is connected, release the remote control button, the relay is disconnected. 8. Switching: Press the remote control button once to connect the relay, and press the remote control button again to disconnect the relay. 9. Latch: Press the remote control button A, the relay is connected, press the remote control button B, the relay is disconnected.
