I do not understand the arrow going from A to B on the schematic.
If it is another relay that goes there. Why use more than one relay?

Jesus,

The relay drawing is there to explain how the A, B and C connector output will behave when
the correct pulsing is done from the micro controller (implemented in software). The two ICs
to the right in the drawing is single contact electronic relays that in my drawing is connected
together to form a switching relay function as shown. Please look at the data sheets for
the ICs to understand how they work. I posted this drawing to show that in some cases we can
use electronic switching that are ready made and easy to implement. The ICs has the same
function as opto-couplers with a input LED to control the output mosfet transistors.

I will read the data sheets. But I still have questions about the circuit perse.

The output marked A, is it positive?
Are there two different output signals on B and C?

If there are two signals, then, the two separate relays inputs to be relayed must be connected to the charging diode, at least this time?

Do you have the code that suppose to run that circuit?

Forgive me for asking so many questions. But even though I can draw a circuit, I am a newbie on microcontrollers.

This is how I understand it will work:

Jesus,

May I suggest this circuit instead, since you have little experience with micro controllers.
I have not build this circuit, but I think it will work in your setup. The feed back part will only
work with the TIC106D SCR or any low trigger current SCR.

Jesus,

Here is a variant using a electronic relay. The relay is a opto-coupler with a LED inside
and needs to be feed pulses from a 555 IC running at 12VDC. The frequency of the 555
must be set so that the capacitor never goes above 55 volt.
