Hi,
I'm using two NI DAQ cards (NI 6036E and NI 6034E) in a WIndows XP based PC to run 11 relays in an industrial system. However, everytime I exit the VI all the relays will start to oscillate and won't stop until I restart the VI. I've measured the digital output voltages while closing the VI and found that they would sink down to zero right after the VI stopped, but rise back to 2.8 VDC after a few seconds. Apparently that was enough to temporary energize the relays but not enough to hold them, and hence the oscillation. Is there anything I can do to modify either the VI or the hardware so this will not happen? Thank you.
