4 Channel Transmitter and Receiver Remote Control Gates

Question from customer:
I am looking for a transmitter and receiver with at least 3 buttons (4 max ) to be used to open and close my gate. I don’t know which is better RF or UHF? Do you have anything that can work for me? I will do the electronics all I need is the option to latch or momentary relay outputs.
Answer：
We recommend 4 channel 12V multi-mode remote controller (S4C-DC12+C-4). It operates in toggle, momentary, latched and toggle + momentary control mode (set the mode as you like freely). You can use it to complete four operations at the same time. For example, turn the light on, open the door or control other dc/ac electrical devices in the meantime. It is applied for light remote control, motor remote control, garage door remote control, gate remote control, etc. We think this remote can be used for controlling gate. That is to say, you can use this remote control to control one or two motors of your gate. To realize gate opening and closing, one motor needs two relays to support.

Secondly, it is the wiring. Suppose you have two gates to remote control. We will wire motors to receiver according to the wiring diagram. B is the common terminal. A is the closed terminal and C is the open terminal. Usually, one relay can only switch on and off one motor. So each two relays can control one motor rotate in positive and reverse direction. We connect two motors to B terminals to every two relays respectively. Connect terminal C to the positive and connect terminal A to the negative.
application circuit
We choose momentary working mode: only connect Jumper-1. (We usually use momentary mode for motor controlling. Or you can also choose latched mode if you want.)
Press and hold button 1, motor 1 rotates in positive direction, gate 1 is opening. Release button 1, motor 1 stops.
Press and hold button 2, motor 1 rotates in reverse direction, gate 1 is closing. Release button 2, motor 1 stops.
Press and hold button 3, motor 2 rotates in positive direction, gate 2 is opening. Release button 3, motor 3 stops.
Press and hold button 4, motor 2 rotates in reverse direction, gate 2 is closing. Release button 4, motor 2stops.

Short Description of Toggle / Momentary / Latched Working Modes

Generally there are three working modes for rf remote controls: toggle, momentary, latched. Toggle mode is used most often. Controlling lamp, for example, press the button of remote, turn on the lamp; press the button again, turn off the lamp. Momentary mode can be set to control rolling blind or rolling door. Press and hold the button of remote, open the blind or door; release the button, close the blind or door. Both toggle and momentary mode are motivated by single relay, which means you can work these two modes with single button remote. As regards the latched mode, it is motivated by relay group. For relay group, only one relay will be on at a time, e.g. press remote button A, relay A will be on, and relay B will be off; press remote button B, relay B will be on, and relay A will be off. To be more specific, when you control the lamp by latched mode, you should prepare at least two buttons remote. Press button A, the lamp is on; press button B, the lamp is off. Online s...

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...

AC Lamp is Controlled by Customized Delay Time RF Remote Controller

Image
We recommend 1channel 110V~220V customized delay time controller (S1RD-AC220+C-2). At first, it must be set delay time in advance. According to your own actual requirement, you can set delay time you want. e. g. delay time: 20 seconds. You cannot change delay time once it is set. It is applied for controlling lights, motors, fans, electrically operated door/ lock/windows/ blinds/ cars or other appliances with AC 110~240V or DC 0~28V. You can turn on/off device on the receiver with transmitter from any place within reliable distance (theoretical distance 100m), the wireless RF signal can pass through wall, floors, doors and other obstacles. Wiring: Initial state: B, C = Normally Open; A, B = Normally Closed. AC lamp is wired to normally open terminals B&C. And add additional ac power to AC lamp. The delay time is set in advance. It is non-adjustable.   Press button 1: Turn on the relay (connect B and C, disconnect A and B) After ...
