Home Automation Control

Question: I want to control a 12V motor to run forward and reverse in order to extend and retract a little sign. Can this controller be programmed to stop running the motor (once the sign is out and in fully)? I don’t want to burn out motors once they reach the end of the track. If not, what do I need to buy to control my motor the way I need? Answer: We recommand model 0020016 (S1FD-DC12 & CA-4) . This model is a reversing controller, with forward-reverse-stop capability. You can rotate the motor in the positive or reversal direction with the transmitter from any place within a reliable distance, wireless signal can pass through walls, floors and doors. It has two limit switches, when the rotation is overdone, the limit switch S1 or S2 will be activated, then the motor will stop automatically.

Reversing motor can be applied to conveyors, awnings , winches ; or electrically operated doors, windows, blinds or other mechanicals and appliances. Generally we use motor controller to reverse motor. Easy wire connection makes it easy to operate. But if you just have ordinary wireless remote controls , is it possible to use them to reverse the motor? The answer is yes. Take dc motor for example, today we’ll talk about how it works. Firstly you need to prepare: 1 x 2 channel receiver in dc12v (latched mode) 1 x 3 buttons transmitter 2 x dc12v power adapters Some lines Secondly, see the wiring diagram below, K is normally open terminal; B normally closed terminal and D common terminal. Connect terminal K to the positive and connect terminal B to the negative. Terminal D is supposed to be connected to the motor. In order to avoid interference to motor, power supply for the motor and the relays should be different. Initial state: terminal B &...
