Hello. I want to control 14 valves(12VDC) with labview, but I do not know much about it. IIs there anyone who can recommend some PCI,relay,cable, connector block with reasonable price to me? I have ER-16 and NB1 cable now.Many thanks.
How much current is needed to drive the valves? It would be easier if you could supply a data sheet or at least a model.

You can take an usb daq with digital outputs. You can connect these to a relay or a transistor, be sure to but a diode anti parallel to counter inductive spikes. These can damage your daq.
