Customized Time Delay Remote Control module is special designed for customers who want to customize the remote control with fixed time delay function. Once the product is product with confirmed delay time horizon by customer, the delay time horizon cannot be adjusted. So the time delay function will be programmed according to their actual requirement. Usually, one relay only can switch on and off the motor. It doesn’t make it rotate forward and reverse. We can use this kind of 2 channels remote to realize the motor positive and reverse direction. Let’s see the demonstration. We prepare this following material. See the wiring diagram. A&B terminals are normally closed; B&C terminals are normally open. That is to say, B is the common terminal. DC motor must be connected to common terminal B without any doubt. Connect terminal C to the positive and connect terminal A to the negative. Note : In order to avoid interference to motor, power supply for the motor and the receiver s...

Question: 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: We think this product may be you want – Time Delay module (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....
