315Mhz/433Mhz 9v Remote Controller for Electron Microscope’s Motors

Question from customer:
I use a manual switch to control 4 9V motors of my electron microscope and each motor works in 150ma (0.15a). In addition, only one motor works when I press button of remote control each time. Now I want to remote control them, have you got any suitable remote for me?

Answer:
We thought this 8 channel rf remote transmitter & receiver is very suitable for you . It can be used to control at most 8 on / off electrical devices. With characteristics of strong anti-interference, reverse power protection and over current protection. Three voltages dc9v, dc12v and dc24v are provided to choose. It is widely applied to control many kinds of lights, electrically operated doors / gates / windows / blinds and so on. It works with 8-button transmitter and their transmitting distance can reach to 500m.

This is the wiring diagram.
circuit
Wire each motor to the normally open terminal “B”. According to the diagram, you can do wiring like above. Even though there are 8 working modes in it, you can choose ”Momentary mode” which is applied in motor’s rotation.
Control mode Momentary (Channel 1~8): Press and hold -> On; Release -> Off.

Press and hold button 1: Motor 1 rotates in positive direction
Release button 1: Motor 1 stops rotation
Press and hold button 2: Motor 1 rotates in reverse direction
Release button 2: Motor 1 stops rotation

Press and hold button 3: Motor 2 rotates in positive direction
Release button 3: Motor2 stops rotation
Press and hold button 4: Motor 2 rotates in reverse direction
Release button 4: Motor 2 stops rotation

Press and hold button 5: Motor 3 rotates in positive direction
Release button 5: Motor 3 stops rotation
Press and hold button 6: Motor 3 rotates in reverse direction
Release button 6: Motor 3 stops rotation

Press and hold button 7: Motor 4 rotates in positive direction
Release button 7: Motor 4 stops rotation
Press and hold button 8: Motor 4 rotates in reverse direction
Release button 8: Motor 4 stops rotation

Only one motor works when you press the corresponding button on the remote.
