I am working on a project that requires the use of relays. I am using QM2N1-D24 relays.
http://www.automationdirect.com/static/specs/qmrelays.pdf
I have a Cdaq-9174, and a 9205 analog input as well as a 9263 analog output. I also have a 24V 5A DC power supply. I need to set up a circuit that will allow me to pragmatically open and close the relays. My analog output doesn't seem to be powerful enough to open the relays, so I feel like I'm missing a piece of the puzzle. Can anyone tell me how they would accomplish this task?
(I need to use the relays to control passing the 24V from the PS.)

well, you are right in saying,"My analog output doesn't seem to be powerful enough to open the relays."...you need some sort of a driver for your relay use. That could be a TTL- ULN, Optocoupler, NPN, Fet,SSR and the list goes on....
here's an example using a USB6009 DigOut,12Vdc source and a TTL-ULN, but in your case...it should be a 24Vdc
