It's not clear what you want. A DC-power supply has a plus pole and a minus pole. You certainly mean a component with an open collector output that is somehow triggered/switched on, right?by the open collector signal from a power supply.
SGT. I was being facetious, kinda mead I guess. He wanted a relay circuit so I gave him one. Since there was almost no supporting information as to specific requirements I just googled and posted a "relay circuit!"5v/500 Ohms means that the LM339 would have to sink 10mA; where it may only be able to sink 6mA. It might work, but I wouldn't guarantee it.
An LM311 would be a better choice.
