Remote Control Electromagnetic Lock

Image
Electromagnetic lock is a locking device that consists of an electromagnet and an armature plate. The principle behind an electromagnetic lock is the use of electromagnetism to lock a door when energized. Essentially it consists of an electromagnet attracting a conductor with a force large enough to prevent the door from being opened. That is to say, if only we could cut off power supply and make electromagnet force between electromagnet and armature plate to disappear, the door would be opened. Furthermore, we just try to use a direct dc output momentary remote and one button transmitter to cut off electric power to open the door. The following demonstration will show. At first, we prepare material. The wiring When we supply power to electromagnetic lock, electromagnet will attract armature plate through magnetic force. The door is locked. When we press button, the power supply will be cut off. The door is open as soon as electromagnetic lock unlock instantly. What’s more, t...

Wireless Remote Control Power Strip

Image
Power strip is a block of electrical sockets that attaches to the end of a flexible cable (typically with a mains plug on the other end), allowing multiple electrical devices to be powered from a single electrical socket. Power strips are often used when many electrical devices are in proximity, such as for audio/video and computer systems. They are reliable, convenient and cost-effective. But you still have to press the socket switch by hand to power up and down the devices. So how about using our rf remote controller to control the power strip? We can wire the power strip to the receiver and use wireless transmitter to control it. Now let's have a try. First of all, we prepare things as follows: 1 x ac high power rf remote controller 100m 1 x power strip 3 x lamps 1 x power plug for the receiver Supposing the power strip is applied to powering 3 lamps up and down. Then we start wiring. Connect the power plug wires to the input terminal of receiver, so that it c...

How to Make Motor Rotate in Positive and Reverse Direction by High Power Remote Control

Image
We are going to demonstrate that our 30 A high power remote controller controls high power motor to rotate in positive and reverse direction. This kind of controller is activated by dc 12v power supply with 30 A current output of each relay. It is very favorable for high power device. It also has four working modes including toggle mode, momentary mode, latched mode as well as momentary + toggle mode. First of all, let’s see material preparation. 1 x 2 channel dc high power remote control receiver (S2PU-DC12) 1 x 2-button remote transmitter (C-2) 2 x dc12v power adapters Some lines Secondly, see the wiring diagram below, B is normally open terminal; C is normally closed terminal and A is common terminal. Connect terminal C to the positive and connect terminal B to the negative. Terminal A 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. Switch on the power O...
