Dear All,
I want to interface sourcing controller output to open collector input as attached drive interface discripotion.
Please help me which configuration should use to work in solid state technology rather then relay circuit.
Thanks

 

The drawing you presented seems to be a good design. I have difficulty understanding your question. Are you looking for the part which should be on the left of the drawing you provided? the, "sourcing controller"?

 

Dear Sir,
I have host controller which switches 24V(+) signal and 0v common and as per servo drive have 24V(+) common and swtches 0V. so i want to design interface circuit which convert input sourching signal to open collector output.

 

There is something wrong about the photocoupler, because when we want to using the the photocoupler, it means that we need isolated from the input to output, so the Anode of LED and the C of phototransistor can't connected together.

 

Yes you may consider that it is photo transister of opto coupler and there is no connection between led and photo transistor.

 

Dear all,
I have proposed circuit to convert signal by using opto isolator so please verify me this circuit upto 100KHz signal and is it implementable.

 

A common GND is not complete isolation, if that is enough for your application then it's ok, otherwise the GND have to separated.

 

I have only issue for compatibility which i think working fine.
I have implement this circuit but it has issue that input resistor (1Kohm) heated during running. And is this circuit behave well at frequency of 200KHz.

 

Maybe your application no need to use the photocoupler still could working fine, just maybe.

Yes, it would get hot.
But you show 10K ohm.

Current is already limited by 2K in servo drive.
If correct, then no other resistor is needed.

Re-calculating the value of resistor or increasing the value of watt of the resistor to reducing the heat.

 

But is the resistor needed?

Isn't this opto led in series with the 2K and opto led in the servo?
