How To Remote Control Four Reversible Motors

Question from customer:

I want to buy a controller which can control four 12 volt reversible motors. Is this possible with one of your products?

Answer:

We recommend 8 channel 5 A RF remote control kit—S8CA-DC12 and 8 button transmitter —CV-8. It operates in 8 working modes and also used to control at most 8 on / off electrical devices. General speaking, it is widely applied to control every kind of lights, electrically operated doors / gates / windows / blinds and so on. The working distance is 500m. Normally open and closed connective terminals can connect to AC110~240V or DC0~28V power supply.

According to customer’s requirement, we try to show how to control 4 motors. Firstly, we prepare the following material.

1 x 8 channel dc remote control receiver (S8CA-DC12)

1 x 2-button remote transmitter (CV-8)

2 x dc12v power adapters

4 x motors

Some lines

The wiring is just a little complicated. Please see the wiring diagram below, B is common terminal. Each motor is supposed to be connected to B terminals of every two relays. A is normally closed terminal and C is normally open terminal. Connect terminal C to the positive and connect terminal B to the negative.

Operation

There are 8 working modes in it. Here we only choose the momentary mode for demonstration and control motors at random.

Control Motor 1

Press and hold button 1, motor rotates in positive direction; Release button 1, motor 1 stops. Press and hold button 2, motor rotates in reverse direction; Release button 2, motor 1 stops.

Control Motor 3

Press and hold button 5, motor rotates in positive direction; Release button 5, motor 3 stops. Press and hold button 6 motor rotates in reverse direction; Release button 6, motor 3 stops.

How to Ignite Momentary Firework by Firework Remote Control System

1 CH RF remote system for firework is our new product. It can ignite various kinds of electric fireworks directly or ordinary firework through fireworks electric ignitors, or light momentary firework ,which reduces accidents like skin burn and accidental explosions. However, launching this momentary firework will be more dangerous because it is sparked in a second and its sparks can fly 2 meters high. We will try to ignite momentary firework with this kind of remote system. It is much safer method to ignite firework.

This new product contains 1-button remote transmitter and 1-channel receiver. Wire the momentary firework to the receiver, the momentary firework can be remotely controlled by remote transmitter from any place within a reliable distance; wireless signal pass through walls, floors and doors.

Firstly, we should prepare some material. Look at the following picture below. There are firework system, one-button transmitter and momentary firework.

Connect wire of momentary firework to black and red terminals on receiver.

Turn on the power switch on receiver. Press button, ignite momentary firework.

Caution:

Any inflammable and explosives material must be far away when igniting fireworks.

Anyone is far away from the firework more than 50m when it is ignited.

Time Delay Adjustable Remote for DC Motor

Reversing motor can be applied to conveyors, awnings, winches, electrically operated doors / windows / blinds or other electrical devices. To make the motor rotate in positive and reversal direction, we try to use this kind 2 channels adjustable time delay remote control kit to control dc motor.

Firstly we prepare:

1 x 2 channel delay time adjustable receiver (S2DA-DC12)

1 x 4-button transmitter(C-4)

2 x dc 12v power supply

Some lines

Secondly, see the wiring images 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.

Thirdly, it comes to operation

At first, we set delay time 8 seconds for relay 1 and 10 seconds for relay 2. Then switch on power.

Press button 1, the motor rotates continuously in the positive direction.

If we want to interrupt the rotation, we can press button 3, the motor stops rotating immediately.

Press button 2, motor rotates continuously in the reverse direction.

If we want to interrupt the reverse rotation, press button 4, the motor stops right away.

Time Delay Mode

Press button 1, the motor positive rotation will last 8 seconds which is set in advance, then stops rotating.

Press button 2, the motor reverse rotation will last 10 seconds which is preset, then stops rotating.

2-channel Wireless Remote Switch On and Off Light and Lock

One of our customers lives in large house in the countryside and enjoys a stretch of green field. Recently, he bought an adjustable time delay control kit from us because he wants to control his door lamp and lock beside the door. When he drives in and out, he can press button to open and close the door and even he can control lamp in the evening. (as the following picture shown）

This 2-channel wireless remote switch, which we provided, operates in time delay control mode. Adjustable delay time can be 0 second~99 hours. For its 2 channels, you can adjust delay time for two relays optionally according to your actual requirement. Our customer used it to turn on the lamp and open the door in the meantime.

We would like to show the simple procedure.

After preparing material, we do some wiring. Here is the wiring picture.

The remote control kit is installed on the wall. (The following is what customer did.)

The lamp and electric lock connect to normally open terminals B&C of relay 1 and relay 2 respectively. The customer adjusted delay time 1 minute for relay 1 and 30 seconds for relay 2. Button 1&3 controls relay 1; Button 2&4 controls relay 2. He drives in and out in the daytime, he can press button 1 to open the door. The door will close by itself after 30 seconds. Of course, he can press button 3 to close it immediately as soon as he goes out of the gate. In addition, lamp need to be turn on at night, he can press button 2 to turn on the lamp. And he can press button 4 to switch off the lamp at once or let it go out by itself.
