Electron Microscope’s Motors are Controlled Remotely

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.

Short Description of Toggle / Momentary / Latched Working Modes

Generally there are three working modes for rf remote controls: toggle, momentary, latched. Toggle mode is used most often. Controlling lamp, for example, press the button of remote, turn on the lamp; press the button again, turn off the lamp. Momentary mode can be set to control rolling blind or rolling door. Press and hold the button of remote, open the blind or door; release the button, close the blind or door. Both toggle and momentary mode are motivated by single relay, which means you can work these two modes with single button remote. As regards the latched mode, it is motivated by relay group. For relay group, only one relay will be on at a time, e.g. press remote button A, relay A will be on, and relay B will be off; press remote button B, relay B will be on, and relay A will be off. To be more specific, when you control the lamp by latched mode, you should prepare at least two buttons remote. Press button A, the lamp is on; press button B, the lamp is off. Online s...

Remote Control Electromagnetic Lock

Image
Electromagnetic lock is a locking device that consists of an electromagnet and an armature plate. The principle behind an electromagnetic lock is the use of electromagnetism to lock a door when energized. Essentially it consists of an electromagnet attracting a conductor with a force large enough to prevent the door from being opened. That is to say, if only we could cut off power supply and make electromagnet force between electromagnet and armature plate to disappear, the door would be opened. Furthermore, we just try to use a direct dc output momentary remote and one button transmitter to cut off electric power to open the door. The following demonstration will show. At first, we prepare material. The wiring When we supply power to electromagnetic lock, electromagnet will attract armature plate through magnetic force. The door is locked. When we press button, the power supply will be cut off. The door is open as soon as electromagnetic lock unlock instantly. What’s more, t...

AC Lamp is Controlled by Customized Delay Time RF Remote Controller

Image
We recommend 1channel 110V~220V customized delay time controller (S1RD-AC220+C-2). At first, it must be set delay time in advance. According to your own actual requirement, you can set delay time you want. e. g. delay time: 20 seconds. You cannot change delay time once it is set. It is applied for controlling lights, motors, fans, electrically operated door/ lock/windows/ blinds/ cars or other appliances with AC 110~240V or DC 0~28V. You can turn on/off device on the receiver with transmitter from any place within reliable distance (theoretical distance 100m), the wireless RF signal can pass through wall, floors, doors and other obstacles. Wiring: Initial state: B, C = Normally Open; A, B = Normally Closed. AC lamp is wired to normally open terminals B&C. And add additional ac power to AC lamp. The delay time is set in advance. It is non-adjustable.   Press button 1: Turn on the relay (connect B and C, disconnect A and B) After ...
