How to Control 12V and 9V Motors Run Back and Forward

Question from customer:
I want to run a 12V dc winch that uses a car battery for power. I also want to run a small 9 volt dc motor. And small motor is powered by small calculation power supply. I wonder if there the remote controller which can be used for those two motors which need two different voltages to supply to rotate in forward and reverse direction.
Answer:
If you want to remote control 2 motors’ back and forward, you need 4CH normally open/closed contact remote control kit (S4C-DC12+C-4). Each relay can only activate motor run at one direction, so 4 relays can realize 2 motors to run two directions respectively. This 4CH RF wireless remote control switch operates in toggle, momentary, latched and toggle + momentary control mode (set the mode as you like freely). You can also use it to complete four operations at the same time. But For example, turn the light on, open the door or control other dc/ac electrical devices in the meantime. It is applied for light remote control, motor remote control, garage door remote control, gate remote control, etc.
4 channel remote control
Here is the wiring diagram. A&B terminals is normally closed, B&C terminals is normally open. We usually connect motors to normally open terminals. Motor 1 is connected to B&C terminals of relay 1 and relay 2. Motor 2 is wired to B&C terminals of relay 3 and relay 4. And supply power to the receiver. Owing to no current output for motors from receiver, so 2 motors must be supplied power with different voltage individually as your requirement. Motor 1 is supplied DC 12V. Motor 2 is supplied DC9V.
application circuit
Our suggestion is momentary mode for controlling two motors’ back and forward rotation. After switching on power, press and hold button 1, motor 1 turns in positive direction; press and hold button 2, motor 1 turns in reverse direction. Press and hold button 3, motor 2 turns in positive direction; press and hold button 4, motor 2 turns in reverse direction. If you release button, motor will stop immediately.
Note: Momentary mode: Press and hold button →On; Release button →Off
