Converter for 0-10V Sourcing Output to Sinking Input for LED Drivers in Dairy Barn

I am installing a sophisticated ventilation comtroller in a dairy barn that  also includes a day/night lighting control using a 0-10 volt sourcing output.The problem is the LED Drivers in the lights require a 0-10v sinking type controller.Are there any converters out there to convert a sourcing output to a sinking type? 66 Light Fixtures total,so it would have to be fairly big.

Thanks for any suggestions.

Hi

I don't know much about sourcing and sinking. But here is something I found about them, http://digital.ni.com/public.nsf/allkb/A10122C63A7F5CFE86256B4C007491DD.

In your LED drivers, what do you need? a high or low input? If its a low input, what I understand is that the output of the sourcing is connected to a pnp transistor. Then the input of the LED driver would be connected to the emitter of the transistor and then the collector to the ground. Just look for a way to ground the LED drivers. The transistor can be BJT or FET. But I would prefer FET.

If High, I think you wouldn't need a converter. Sink is like an open-collector or open drain.
