Question from customer: “I'd like to order a 220v electric hoist to raise and down a bridge boat with a remote control. The ascent and descent should be done when someone is still pressing the remote control button, as there is no stop. What would you like me the most suitable product? Thank you in advance." Answer: We recommend the ac 100V~240V momentary motor controlling model (S1FM-AC220& CV-2-2). It is specially designed for motor controlling because two relays are inserted inside. One relay is used for motor rotating towards “UP”. Another relay is used for motor rotating towards “DOWN”. There are “UP”, “COM” and “DOWN”contacts from output terminal. This kit can controls motor of rolling blinds, doors, projection screens, awnings, pumps, conveyors other appliances and mechanicals. The transmitting distance is usually about 500m in the open air.

Question from customer: “I received the item— 2 channel motor controller( S2PF-DC12+1CV-6-2) and installed it yesterday on my remote control lawn mower that I have made. Per the instructions for momentary control, I can get 1 motor to work at a time, either motor but only one and only in forward. I then changed, per your instructions for latch and each motor will go forward if started with remote, #1 and then #2 both will run forward only, but they cannot be controlled to go in the direction that I choose. Neither motor will reverse in any mode. I have to be able to control each motor independent of each other so I can drive the mower right and left to go the direction I want. Please advise!” Answer: You chose the 2 channel motor controller. Although the controller has two relays for two motor, two relays will work in the same mode. That is to say, your two motors only work in momentary mode or latched mode for one time. We recommend two sets of 1 channel dc motor controllers (S1...

We made a remote control kit which consists of a wall-mounted switch and a remote receiver (S1X-AC220&HR-1). When we use ordinary switch to switch home appliances off and on, we should do some wiring for home appliances, some time it is very complicated and time- consuming. Our RF wireless wall mounted switch looks like universal switch from appearance, but it is wireless and operate by RF signal that can pass through walls, floors and doors. It is can be simply affix to any place you want by double faced adhesive tape. Through RF signal, you don’t have to wire between switch and appliances. Wall-mounted switch works with remote receiver to remote control ac lamp. Here is the wiring diagram. Wire ac lamp to OUTPUT of receiver. And add power supply to receiver. This kind of receiver is designed for AC output terminals so that lamp can get power from output terminals of receiver directly. Setting different control modes (We usually set toggle for lamp controlling.) Setting ...

Question from customer: Whether we can get the receivers with different voltage versions? For example 2 piece of 24 volt and 2 piece of 240 volt. Answer: Yes, it is possible. We recommend those two kinds of receivers—for 24V version, it is 24V DC input receiver (S2UB-DC24). For 240V version, it is 100V~240V input receiver (S2U-AC220). Both of them have two relays on the PCB. So there are four channels totally for your devices. They can pair up with long range transmitter (CB-4). It can control lights, motors, fans, electrically operated doors/locks/windows/blinds/cars or other appliances with voltage AC 110~240V or DC 0~28V. Owing to normally open& closed contact, you should add additional power supply to your devices besides your receivers. But you can do as following wiring method to save power supply adaptors. Wire devices (lamps) to B terminals of each relay, using wires to connect devices to output terminals of each receiver. For dc input receiver, we supply dc 24v p...

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...

Someone wanted to find the best solution for wireless motion detection system. He just wanted 6 transmitters to be 6 motion sensors. And a 6-channel receiver can identifies each transmitter after activation. That system is to run on 12V. Wireless Infrared Movement Detector and 6-channel receiver can help in this situation. We can pull out the antenna of the movement detector at first. Then push down the power switch of the movement detector to position "ON". After 60 seconds delay, the movement detector will enter into the automatic detection state. Within the area of detection, the movement detector will be triggered by movement, LED will turn on green light for 2 seconds, and the movement detector will send alarming message to 6-channel receiver. We can connect 6 LED lights to the receiver in advance. If any of movement detectors is triggered, the corresponding LED lights will shine. Online shop:  http://www.carymart.com/
