Voltage is sent out to the lnbf from the Lnb in. I beleive whenever you open a software to watch feeds, voltage is sent out. If the card is not in used, no voltage sent out at all. No voltage from the lnb out. But remember if you decide to slave the second receiver to the card, you should turn off the lnbf power of the 2nd receiver. If not, PC will pass from the second receiver to the card, which might get card damaged permanently. Radio Shack sells DC blocker, which can be used to block the DC from the 2nd.
