Time Controller——Better Choice

Recently, we promote a new product— multi functional clock and time control module. It is compatible with various working modes which can work individually and together. Its main functions are as follow. Time point or time period; controlling timing cycle by time period; controlling time relay together by time point, time period and voltage detection; discharge instrument function; week & days control function.

This controller can be widely used in clock and time control applications. For example, in those blazing summer days, air conditioners are absolutely necessary in offices or families. Long time operation of air conditioners are neither for good health nor for energy-saving. For good health and energy-saving sake, you can use this kind of controller to switch on and off the air conditioners. After wiring, you should preset time in advance. You choose P-2 mode (week control mode). You can preset Monday to Friday, 9:00am—Open; 12:00am—Close; 1:00pm—Open；5:00pm—Close. Saturday and Sunday: Close. The pre-set parameters can be saved after power turns off, and continues to work after power turns on.

The picture shows mode setting and timing.

It is 9 clock in the morning, the air conditioner will be turned on by itself. When they knock off at 12:00 and go out for lunch, the air conditioner will be turned off automatically. And 1:00~5:00 pm, the air conditioner is working all the time during this time. The air conditioner won’t work at weekend.

How to Remote Control Electromagnetic Lock

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, this rf remote control sends out rf signal which can pass through walls, doors as well as other barriers. You can remote control the electromagnetic lock to open the door as long as you stay within a reliable distance.

Remote Controller is Used in Water Feeding System

I own a cattle farm and I have to add water to my feed ration when I feed the cattle. I used to have to pull the tractor and trailer up to the water pipe, climb down from the tractor and walk around the side, plug in a submersible pump and run water into the feed trailer.

It is fairly inconvenient. I am wondering if there is a way to make that all remote controlled. Soon, I found single channel AC high power module.

I used the remote controller to toggle power to a timer relay which in turn powered the coil of a small motor starter. Through the motor starter, I ran a receptacle which plugged the submersible pump into.

Here is the wiring.

So when I press the remote control button 1, the control unit then energizes the timer for 3 minutes to activate the motor starter for 120volts submersible pump running. When I think I have enough water in feed ration, I press the remote control button 2 to stop water flowing and I continue on with the feeding of the cattle. The reason for the timer in the circuit is a fail-safe. If I forget to turn off the pump when there is enough water in ration and drive away without turning off the pump, the timer will only allow the pump to run for a maximum of 3 minutes, preventing 3000 gallons of water being pumped out on the ground.

So far the unit seems to work flawlessly and I am VERY pleased with how the whole system works.

How to Make Water Trickle out From Tap Automatically

One of our customer wants a motion detector controls a solenoid valve which works in a tank for hand-washing.

We recommend this smart infrared detector model of 0040101. The module can accurately detect any moving objects within the detective range and commonly be used to detect human body movement. It has higher sensitivity and broader detective range than others. The motion sensor detector will work with the solenoid valve.

Wire the solenoid valve to the detector according to the wiring diagram.

When someone puts his hands under the tap, the PIR motion sensor detector will detect and indicate the solenoid valve installed on the tap to open. The water will trickle out from tap for hand washing. It lasts about 20 seconds. The water will stop trickling out after 20 seconds.

Time Delay Remote Control Activate Hot Water Circulating Pump

Question from customer:

I have a hot water circulating pump: 115V AC 0.4A. I want to be able to turn it on from 3 different locations within the house and have it turn itself off after 2 to 3 minutes. Do you have any equipment which will do this?

Answer to this question:

We think this product may be you want – ac time delay remote module 0020483 (S1DA-AC220-ANT2 & CB-2). The receiver is relay output (normally open and normally closed). Power supply for the receiver and the water pump are different. That means it will not cause electromagnetic interference during water pump operation. With the external extend antenna, the RF signal can pass through walls and doors as well as floors.

The wiring diagram is shown below.

The water pump will be connected to normally open terminals “B&C”.

After wiring, press buttons of “＋” and “－” on the timer, adjust delay time from 0 second to 99 hours. “H” is Hour, “M” is Minute, and “S” is Second. As you said, we set 3 minutes.

So we set “M 0 3”, it means the delay time is 3 minutes. Press big button: Turn on hot water circulating pump. It will stop working by itself after 3 minutes. You can also press small button to turn it off immediately.

According your requirement, one receiver can be paired with 3 transmitters. Any of transmitters can remote control the pump. You are able to turn it on from 3 different locations within your house and have it turn itself off after 2 to 3 minutes by itself.

So your home hot water circulating system will be like this.
