Basic electronic - disconnect the circuit

[Slebo]

Hi all out there


I have this wire that has to be connected as default setting, but in some case i want to stop / interrupt / disconnect the connection, dont know the right term .

To do this i have bought a remotecontrol for that, i haved linked to what im talking about is in buttom of this page.


I know i could just wire up to the controller, but then i had to use the remote every time i wanted to connect the wires, but i want to reverse it. So that i only have to use the remote whenever i want to cut the connection between the wire. I hope i explain my self good enough for you to understand my problem

That item you linked too. Its two channel and its got two relays (blue square jobbies) and six terminals, so I think you can select either a normally closed contact or a normally open contact to operate the external circuit.

Can you tell us how are the contacts marked ?
Also you can just do it by trial and error, starting with only the first 3 terminals on the 6 terminal block, those first three will almost for sure do what you want.

 

[Slebo]

From what i can tell, 1-3 is the first and 4-6 is the second. and i think its (+) (-) (N), but not sure

Best of all, there was no manual when i bought it, so it is by trial and error like u say

 

[Slebo]

When you say its either a normally closed contact or a normally open contact, do you mean that u think i can choose to set it as open as default ?

What is the current, voltage or power rating of whatever you want to disconnect?
The relay contacts are for fairly high current (10A) so they will make a poor connection or no connection to an audio signal or other low level and low power signal after a while.
The contacts are plated with silver that corrodes quickly into silver oxide (it is black) but a high power load produces a spark that burns off the oxide so it works well for high power loads. A low level signal produces no spark so the silver oxide prevents connection. Low level relay contacts or switches have gold plated contacts at no extra cost.

Hi @Audioguru and thank you very much for that answer!

Im going to apply it to my scooter which has 12V, from what you wrote, it seems that it aint going to work that well. Do you have another solution? or do you know another model that might suit to my problem?

Another solution is to build one my self, but im not that skilled in this area

Hi,

You never said what is your load. He never said It cant be used for your application.

 

[Slebo]

I think my load is 12V


Here is my setup: or what im hoping to do.

 

[Slebo]

Im planning to take the power from my scooter (12V) and use it to power my switch, and power my application. I hope that answer your question Venkadesh_M, and again thank u!

 

[Venkadesh_M]

Hi Slebo, I asked what is that device, that was my question.

Also what do you mean switch in black wire, Usually black is negative wire, which is grounded all over the vehicle body.

So The switch should be in the positive wire.

 

[Slebo]

Im having a hard trouble translating my device to engslish But ill give it a try

On modern scooters they are restricted by RPM, which are controlled by a little black box called CDI box. My device, when activated it reduces my scooters RPM.

This device is a little black box with a postive and negative wire. and currently it has a manual switch on the black wire which im going to replace with the electronic switch.

I have no idea which ohm and amps its running on, but i know that its running on 12V DC since its getting powered from my scooter

 

[Audioguru]

If you don't know the current in your manual switch then ask an electronics technician to measure it.
I think CDI is Capacitive Discharge Ignition to make the spark for a gasoline engine and its current is very low. Do you want the electronic switch to cause the RPM to always be low?

 

[Slebo]

Its very simple, i want the electronic switch to switch between on and off, with on as default setting. so whenever i power up my switch its on as default

 

[FvM]

As previously mentioned by others, we can expect that the intended function will be achieved by connecting the load through the normally closed contact of one of the two relays. It can be easily identified with a multimeter or continuity tester.

 

[Slebo]

okay thank u, my next issue is, it says it runs on 12V but on the board where i think its powersupply needs to be hooked up, it says this:

Can i still hook it up with 12V here?

 

[FvM]

Can i still hook it up with 12V here?

At least a small modification of the board will be necessary. As a first step, you would find out what's the internal power supply level of circuit. If it's 12 V or less, the series capacitor (big brown component near the 230V terminals) can be removed and replaced by a series resistor sourcing a similar current as the capacitor circuit.

I would usually extract a schematic from the respective board part and calculate the modification.

 

[Slebo]

that would indeed have been very helpful, but i cant find any manual.. I guess i have to just try different things.

 

[D.A.(Tony)Stewart]

Slebo without schematic in manual, it is difficult to devise an over-ride on RPM limiter with failure to operate. Running motors at excessive RPM can ruin them faster.

 

[Audioguru]

The circuit board is designed to switch 200VAC on and off.
You should not buy Chinese junk from Amazon that has no information.
