Hi,
Thank you for posting to the NI forums. While the analog outputs may not be sufficient for driving your relay, the digital outputs can provide up to 24mA per channel. Post back if you have further questions.

If you are having trouble driving relays with either the digital or analog, use a transistor, like a 2n4401. This should give you enough boost to drive the relays.

I hate to break it to you this way but, you have got to burn enough power to generate a field that can move that relay contact against the mechanical resistance. Simple Newtonian physics. You need a driver. The ULN2003 is a fairly low-cost solution.
Take care- don't break any more laws of physics.

wana be prog and Jeff,
Did either of you notice that the thread you are responding to is close to two years old?
