How i can i give differential output from sbrio

[irfan789]

i want to connect relay at the output of the sbRIO for switching 

i gave a  (0-7) voltage for 5volt relay from ANALOG OUT and ANALOG OUT GROUND

but relay is not switching  

i tried with a mobile battery  3.7volt it is switching and i found it happened  when i connected -ve and +ve terminals of the battery with the relay

Which sbRIO model do you have?

How much current does the relay draw?

i am using sbRIO model number  9642

i have relays  of 12 volt (current 0.0375A) and 5 volt( current 0.072 A)..
