Reversing motor can be applied to rolling blinds / doors, projection screens, awnings, pumps, winches, conveyors or other electrical devices. Generally we use motor controller to reverse motor. Easy wire connection makes it easy to operate. But if you only have simple rf remote controls, is it possible to use them to reverse the motor? The answer is yes. Here take dc motor for example.
Firstly you need to prepare:
1 x dc 12v 2 channel latching control receiver (S2L-DC12)
1 x 3-button transmitter (C-3)
2 x dc12v power adapters
Some lines
Secondly, as seen wiring diagram below, C is normally open terminal; A normally closed terminal and B common terminal. Connect terminal C to the positive and connect terminal A to the negative. Terminal B is supposed to be connected to the motor.
Note: In order to avoid interference to motor, power supply for the motor and the relays should be different.
Initial state: terminal B & C are normally open; terminal A & B are normally closed. Terminal B outputs negative power and the motor do not work.
Press button ▲ on transmitter, terminal B & C connected to Relay 1 are closed and terminal A & B are open. At this time terminal B outputs positive power, the motor rotates continuously in positive direction.
Press button ■,terminal A & B connected to Relay 1 are closed and terminal B & C are open. At this time terminal B outputs negative power, the motor rotation stops.
Press button ▼, terminal B & C connected to Relay 2 are closed and terminal A & B are open. At this time terminal D outputs positive power, motor rotates continuously in reverse direction.
Press button ■, terminal A & B connected to Relay 2 are closed and terminal B & C are open. At this time terminal B outputs negative power, the motor rotation stops.
