How to Remote Control 4 Lamps from Different Places

One of our customers wants a simple wireless remote operate 4 led lamps from several room at his house. He needs 4 transmitters and a receiver which can be mounted in a designated place. The remote must work from receiver about 50m away and not line of sight through doors and walls.
We suggest him choose dc 4 channel remote control system (S4C-DC12& 4C-1). Maximum working current is 5amp each relay. Working distance of remote and receiver set is about 100m (300ft) in open field. This 4CH 6V9V/12V/24V wireless remote switch operates in toggle, momentary, latched, toggle + momentary control mode (set the mode as you like freely). Easy to install and operate. Just press slightly the button on the remote, you can control universal DC/AC electrical devices. The RF signal can pass through walls, doors and other barriers. As he said, we will set 4 transmitters and this receiver with same 8-bits code in advance so that they can work together.

Operation modes:

• 1) Setting control mode Latched: Disconnect Jumper-1 and Jumper-2.

Control mode Latched (Relay 1~4): Press -> On, other relays Off; Press other button -> Off.

• 2) Setting control mode Momentary: Only connect Jumper-1.

Control mode Momentary (Relay 1~4): Press and hold -> On; Release -> Off.

• 3) Setting control mode Toggle: Only connect Jumper-2.

Control mode Toggle (Relay 1~4): Press -> On; Press again -> Off.

• 4) Setting control mode Momentary + Toggle: Connect Jumper-1 and Jumper-2.

Control mode Momentary (Relay 1, 2): Press and hold -> On; Release -> Off.
Control mode Toggle (Relay 3, 4): Press -> On; Press again -> Off.
We will show you how to remote control 4 led lamps from different places.

2000m Momentary Controller for DC Motor

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 controlled DC motor. Or you can use one power supply for receiver and DC motor at the same time. The wiring method is as follow.

Connect DC motor to B&C terminals. And wire motor to positive and negative terminals of battery. Wire positive and negative terminals of receiver to battery.

Operation is very easy.

Press and hold button, turn on motor.

Release button, turn off motor.

Remote Control Car Sun Shade

Car shades are another common way to protect the vehicle besides sun blinds. The shades for the rear and front windows are designed to be unfolded and sit against the window. These shades are used to protect the vehicle and the passengers from direct sunlight. What’s more, the U.V ray will penetrate car window and can not escape that the car gets hot. So you need car sun shade to protect yourself and your car. And if you could use a remote controller to control those shades which are activated by motor, It might be very convenient and leisurely.


We are going to control motor to make sun shade up and down with this 2 channel momentary remote switch.

Firstly you need to prepare:
1 x 2 channel dc momentary remote control receiver (S2M-DC12)
1 x 2-button remote transmitter
2 x dc 12v power adapters
Some lines

Secondly, see the wiring diagram below, C is normally open terminal; A normally closed terminal and B common terminal. Connect terminal C to the positive and connect terminal A to the negative. Terminal B is supposed to be connected to the motor.
Note: The Power supply of receiver and motor must be provided individually in order to avoid interference between them.


Operation:
Press and hold button 1, the motor rotates in positive direction; Release button 1, motor stops rotating.

Press and hold button 2, the motor rotates in reverse direction; Release button 2, motor stops rotating.

Only to press buttons to control car sun shade in your car to avoid direct sunlight and even protect your own privacy in the daytime. It is simple and convenient.
