Radio remote control + receiver module, incl. 4-channel relay - 12V, 433 MHz

Overview:

• Radio remote control with 4-channel relay receiver module
• Suitable for autonomous control of electrical circuits (e.g. garage doors, windows, car doors, etc.)
• The 4 relays can be controlled separately from each other
• Simple programming via the program button on the circuit board
• Model: KR1204B-4-V06

Transmitter

• Remote control range: 30 m
• Operating voltage: 12 V DC
• Frequency: 433 MHz
• Operating current: 13 mAh
• Code type: fixed code / learning code

Programming instructions:

Connect the module to a 12V DC power source. Ensure that the polarity is correct.

Delete all stored transmitters:
Press the learn button on the receiver 8 times and the codes will be deleted.
After deleting the stored transmitters, all transmitters must be re-learned by the receiver.

Teaching the transmitter: momentary mode

• Press the programming button on the receiver once. Wait a moment, the LED goes out and the receiver switches to learning mode.
• Press the remote control button, the LED display on the receiver board flashes and then goes out. After 3 seconds, the LED indicator lights up again, the learning was successful.

After successful pairing in this mode, press and hold the remote control button (e.g. A) to switch on the corresponding relay on the receiver. Release the remote control button to switch off the relay on the receiver.

Teaching the transmitter: Switching mode

• Press the programming button on the receiver twice. Wait a moment, the LED goes out, the learning mode is activated.
• Press the remote control button, the LED display on the receiver board flashes and then goes out. After 3 seconds, the LED display lights up again, the learning was successful.

After successful pairing in this mode, press the remote control button (e.g. A) to switch on the corresponding relay on the receiver; press the remote control button again to switch off the relay on the receiver.

Teaching the transmitter: Locked mode

• If you select the locking mode, two different buttons must be programmed, the first time for "ON", the second time for "OFF".
• Example: Button A = ON, button B = OFF
• Press the programming button on the receiver 3 times, the LED (on the receiver) flashes 3 times. When the LED lights up, press the button on the remote control. Press button A on the remote control, for example, the LED flashes 3 times. Press button B on the remote control, the LED flashes 3 times. After 3 seconds, the LED display goes out and learning is successful.

After successful pairing in this mode, press the remote control button (e.g. A), the receiver relay corresponding to A is switched on; press the remote control button (e.g. B), the relay on the receiver corresponding to A is switched off and the relay on the receiver corresponding to B is switched on and the relay is opened. Press the remote control buttons A and B simultaneously and the receiver is switched off.

Scope of delivery:

• 1x receiver module, incl. 4-channel relay - 12V, 4CH, 433 MHz
• 2x remote control
