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 ...

Question from customer: I need a 2 channel receiver with 2 remotes 1 channel. One remote control activates the channel A receiver on the receiver and another remote to turn on the channel B on the receiver. Is it possible with the CWB-1 model? And which receiver would like to recommend? Answer: We recommend 2 channel12V multi-mode receiver (S2U-DC12) and two waterproofwireless 50m remotes (CWB-1). We set configured code for them so that they can work together. The receiver is 12V activated and has two relays. When it works with that transmitter, its transmission distance can reach 50m in the open air. There is only one button on each transmitter. It can control lights, motors, fans, electrically operated doors / locks / windows / blinds / cars or other appliances with AC110~240V or DC0~28V. You can turn on/off the receiver with transmitter (remote control) from any place within a reliable distance; the wireless RF signal can pass through walls, floors, doors...

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. Wiring: Connect live wire to terminal “L” and neutral wire to terminal “N”....

Question from customer: I am looking for a long range relay to control a water pump. The water pump now is controlled by a float switch (on/off) at the reservoir 800 meters away. I have 120 volts at both locations and a relay to start pump. Answer: We recommend the 2000m rf AC receiver (S1PUA-AC220-ANT2) and the long range transmitter CB-2N. The receiver is soldered with external extended antenna, which can make its transmission distance at 2000m/6000ft theoretically. It works between AC 100~240V voltage. The maximum working current is 30amps. There are 315Mhz or 433Mhz at your option. The transmitter is special designed because its triggered method is connection and disconnection of two wires. When two wires are connected, the transmitter is triggered and then transmits an rf signal “ON”. When two wires are disconnected, the transmitter is triggered and then transmits an rf signal “OFF”. The wiring method of your water pump will be talked next. A, B terminals are normally open...

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...

Roller shutters or rolling doors have many applications, including applications for vans, garages, kitchens, schools and warehouse. The door is raised to open it and lowered to close it. Both roller shutter and rolling doors provide protection against wind and rain. Now we recommend this kind of rf wireless magnetic sensor (W-13) to install to roller shutters or rolling doors to protect windows or gates from vandalism and burglary attempts. It will send signal to alarm main unit to alert people once it is triggered. This kit contains a sensor, a magnetic bar, a transmitter and 4 screws. It works with 100m in the open field. Alarm time of this kit is 5 seconds. With indication of low battery, you can change battery in time.   Installation : Stick part A (magnetic bar) on the edge of the roller shutter/rolling door, and stick part B on the fixed frame of roller shutter/rolling door Note: The distance of these two parts shall be less than 3-5 cm when the roller shutter/rolli...

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 ...
