Question from customer: I am looking for a radio transmitter receiver 1 channel, 24V, 500 to 1000m, and function: I support the button, close the relay; I loose the button, open the relay. Answer: We recommend the model of 1 channel Momentary 2000m remote control kit (S1M-DC24-ANT2& CB-1). Remote control kit with momentary mode is often used to control motor open/close for electrically operated door/lock/window/blind. Press and hold the button on transmitter, start the motor (close the relay); release the button, stop the motor(open the relay). With external extend antenna, its working distance can reach 2000m (6000ft) theoretically. We have three standard voltage: 9V, 12V, 24V. You can choose the 24V. Owing to one relay on the receiver, it won’t realize that DC motor runs in forward and reverse. It only switches off/ on DC motor. And it is normally open and close relay contact, generally speaking, you should add additional power supply to control

One of our customers is looking for a device to wireless operate a 220v motor for 30 minutes. When he presses a remote control button, the engine starts and runs for 30 minutes then stops. 1 channel rf time adjustable remote controller kit is very suitable for him. The remarkable feature of this kind remote controller is time delay control mode. Adjustable delay time range can be 0 second~99 hours. With time delay adjustable function, it is used in light remote control, garage door remote control, car remote control, etc. It is very easy to do some wiring. Owing to its normally closed and open contact, we can do this following wiring. Motor is wired to normally open terminals B&C. And motor and receiver are supplied 220V power respectively. Press buttons of “＋” and “－” on the timer, adjust delay time from 0 second to 99 hours. “H” is Hour, “M” is Minute, and “S” is Second. He can set “M 3 0″, it means the delay time is 30 minutes. Press button 1: Turn on motor, after delay

Sometimes, you want to remote control more than one electric devices just with one transmitter，but most of remote control systems only allow one command at a time to remote control one device even though they are able to activate 2 or more relays. Or you are just looking for a remote control system with range of only 100m that will allow the activation of least three or four commands simultaneously and then trigger three or four channels on the receiver at the same time. Actually, you thought can be realized if the 4 channel 12VDC long range receiver ’s interior circuit can be changed and pair with 1-button transmitter . You just need only one button on the transmitter that you can remote control 4 devices. Its working distance is beyond your thought. It can reach 2000m (no obstacles). You wire either AC 110~240V or DC0~28V electric devices to receiver because of its normally open and closed contact terminals. Electric devices usually wire to normally open terminals for safety purp

In building wiring, a conventional light switch is a switch, which most used in turn off and on lights, permanently installed on the wall. Gradually, those conventional manual operated light switches may be substituted by wireless remote control switches. Our wireless push-button switch (HT-1) controls light off and on at ease, with stick-on back of switch, we can simply affix the wireless push-button switch to any place we want. Through RF signal transmission, we pair up this switch and 1 channel ac power output receiver (S1X-AC220). First of all, we pair up those two gadgets. Then, we install the rocker switch to wall after uncovering the cover of double-adhesive tape. Next, light is connected to L&N terminal of receiver. Light can get power from receiver if the receiver is powered. Finally, we switch on receiver. This push-button light switch only has one button that alternatively closed and open the contacts. It is Toggle mode. Press button, turn on the light. Press
