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...
