New circuit design for home project

Hello group,

Is there anybody here that could help with a design for a small circuit to
control 3 relays ?

I can provide more details, but I wanted to check first.


Thank You.

Hi John.
Basically, it will be an interface/black box type device that will sit
between two separate devices.

One device will control the other device, with the interface between them.

The device to be controlled currently has a wired remote control (no
electronics, just 3 membrane switches)
One switch turns on a water pump, the other turns on a light, and the 3rd
one turns on a flame.
But, to turn on and off the flame, you need to push a specific sequence of
the 3 buttons.

I have another device that I want to use to control this first device.
But this device uses relays in its output.
It can only turn on, or off the relays.
It cant do something like a macros so that a key sequence can be simulated
using the relays.

I would like to build an interface box that would sit between the two.

So, when the controlling device turns on relay 1, then the interface would
do a momentary on then off on the switch 1 contact for the device being
controlled. When the relay is turned off, then it would do the same again.

But, when the relay3 is turned on (flame), the interface would then do the
key sequence needed to turn it on on the device being controlled.

I'm not sure if my explanation makes sense.
Please let me know if it makes sense.

Thanks!

Hello group.

Can anybody offer some feedback on this ?
I'd like to find somebody that could design the schematic for this.
Is there another group more suitable for this ?

Thanks !

make a drawing at www.yahoo.com ; go to the mailbox the ID is
'schetsen' and the password is 'diverse'. send the drawing to the same
mailbox 'schetsenATyahoo.com'
and I'll see what I can do for you ( for free of course )
 
you also can look on 12mei, there I explain about the system to send a
drawing.

the title is > 'sometimes a drawing is better to understand....'
