1. Antenna has selected frequency input circuit, rather than relying on 1 / 4 wavelength antenna frequency-selective role in controlling the distance can be short or even close to removing an external antenna.
2. Receiver circuit self-radiation of small, together with the circuit module back mesh grounding the role of copper foil shielding can reduce the self-oscillation signal leakage and the intrusion of outside interference.
3. Receiver with high-precision inductor copper skeleton to adjust to the frequency of??after the 315M, which is adjusted using adjustable capacitor circuit receiving the frequency compared to temperature, humidity mechanical stability and anti-vibration performance have greatly improved. Adjustable precision capacitance adjust lower, only 3 / 4 laps of the adjustment range, and adjustable multi-turn inductor can adjust. Adjustable capacitor can not adjust after??, because regardless of conductor or insulator, various media around or invasive capacity will cause the capacitance changes, thereby affecting the receiving frequency. In addition, without the adjustable capacitance??by vibration and dynamic boards boards displacement between; temperature changes will????boards and dynamic changes in the distance between film; humidity changes due to changes in changes in media capacity; long-term Working in wet environments but also due to boards and dynamic changes in the capacity of oxide films, which will seriously affect the stability of the receiving frequency, and using adjustable inductance can solve these problems, because the inductor can be carried out after the adjust??, insulator??agent inductance will not change, but also because of the use of SMD technology, so even if the strong do not have to worry about receiving vibration frequency drift, the receiving circuit to receive bandwidth is about 500KHz, the factory has been adjust the center frequency at 315MHz, receiver chip inductance on the fine-tuning some of the adjustable frequency range of 5MHz, the use of not easily change, so as not to affect performance.

The remote control receiver board, and the website can introduce the 100 meters four button remote control, 200 meters four button remote control, 800 meters four button remote control, 2000 meters four button remote control, such as 500 meters with the use of the emergency button. Uses: used for remote control of a circuit OFF, or a bright light and out.

The blue arrow on the board to receive the location of the PCB through the solder Department can select four-way short-circuit to switch the remote control signal in one of the way (such as remote control key A / B / C / D of the A button) to another also can be red arrows with solder short / open circuit to switch select latch or non-latch mode. The default is open non-latch mode, that is, press the A button, receive board relay pull-in, release the A key if the receiving plate to release the relay. If post-solder circuit latch mode, that is, press the A button, the relay board to receive the merger to maintain suction, only press the B / C / D in any of a button, the relay before being released.

Have practical experience of users will find that, under the same conditions, using M4-chip non-latch plate to receive the remote control distance is much smaller than the L4 latch-type remote distance, and sometimes only half of latch-type or even less than and relays have the phenomenon of pull-in instability, This is because in the non-latched state, the remote control signal required about 30 times per second, synchronization, when the relay controlled by the electrical load, or are prone to interference with other equipment, equipment itself after the electricity generated would interfere with the remote control signal interruption, so that the relay at a job jumping instability.

Here we use a wide anti-jamming technology exhibition pulse method is still used for L4 decoder chip output by 17 feet the signal to do a delay of about 0.5 seconds wide outreach, so that the output signal of the remote control more stable, the development of the remote control station at the gate products that adopt this approach, so that the remote control further, more stable and Practice has proved that lagging 0.5 seconds delay will not affect the operation.

The receiver board can be 200 meters and four button remote control, 800 meters four button remote control, 2000 meters, such as four keys with the use of remote control.

The receiver of the four relays on the board corresponding to the four button transmitter, blue arrow Department can use solder to short-circuit and open circuit switch select latch or non-latch mode. The default is open non-latch mode, that is, press the A button, receive board relay pull-in, release the A key if the receiving plate to release the relay. If post-solder circuit latch mode, that is, press the A button, receive board relays A suction to keep the merger, only press the B / C / D of a button any time, A before the release of the relay, press the That way the relay pull-in, that is to receive remote control board can be the last memory state, and be able to maintain a self-locking until the next time the remote control to receive commands to change the status of the relay.

Each relay has a corresponding red light-emitting diodes to indicate the status of its work, the upper left corner of the circuit board are 12-volt power outlet DC power input, each relay has a corresponding three terminal, are One group of normally open to normally closed contact, between the public side, the left always right for the normally closed, you can control about 220V/5A load, if the long-term control of a larger proposal to increase the load current relay 220V / 20A expansive flows to extend relay life.

The receiver board has also been adopted by non-latch mode pulse broadening anti-jamming technology, so the stability of the remote control, remote control distance and have a lot of customers to buy long-term supporting their products, because the long-term large-scale use will inevitably lead to some failures, here we introduce the way 4J-L4 about the repair techniques.

First of all, you can measure whether or not to receive the first two ends has 5V voltage? , There is no power on the part of the focus of inspection, the general 78L05 are damaged or PCB disconnected (disconnected in general and the PCB pad happened at the junction, it is difficult to detect concealed the naked eye, can be used to confirm multimeter) to receive the first because it is a separate small plate so easy because the transport caused by squeezing or shaking the roots of tear caused by poor contact pad, plus careful observation confirmed multimeter.

Measuring the output of the first receiving terminal voltage, the normal remote control signal receiving board does not generally fluctuate at around 2V, when holding down the remote control when the voltage down to 1V or so, release the remote control hopping transient voltage to 3V, then return to around 2V fluctuations. Can be disconnected if we do not receive the first of 14 to 2272 feet measured between the jumper and then click, or not receiving the first note damaged Change (my website has sales of 315M to receive???first 7 yuan a) Please check if the return to normal 2272 L4 chip.

2272 L4 measurements of the 5V power supply normal? Address whether the dirt area code or address inconsistencies and remote control? Press the remote control 17 feet when it has synchronized voltage output? If there is no damage may be 2272, if the 10 ~ 13 can synchronize the output signal, please Detect whether the overall transistor 8050 non-performing (PCB have latched on to write the word next to the transistor), can short-circuit CE pin board can look at the receiver can latch at job state? If we can explain failures in the total capacitance of the transistor and the 100UF and 4148 diode and 100 ohm resistors here, please check whether it has???

If you are a certain way does not work, please relay this road Detect SC8050 and the LED is bad? Please focus on whether the line PCB inspection, and finally can doubt whether the bad relays can test voltage test. Judging by the fault Occurrence: receiving the first bad-2272L4 damage-PCB disconnected -8050 damage-78L05 damage-LED damage - bad relay.
