Solenoid pinch valves with USB?

[mystmanshez]

Hi I am trying to make a setup using 10 ASCO pinch valve. The idea is to stop fluid from passing through digitally. The pinch valves require 12 V  to allow flow. Also the power is 4W which, im guessing, is HUGE. Is there any way I can setup a circuit with a DAQ card or any USB interface to make this happen? I know Visual Basic and C++. Just started learning LabVIEW like a week ago. Keep in mind i need to operate 10 such valves at the same time (different ONs and OFFs of course). I'm guess the current required is like 0.3 Amps (4/12).

Howdy mystmanshez!

If you are looking for a solution with a USB interface I would recommend compactDAQ. To provide the necessary 3A at 12V for all ten channels you will need an external power supply.  You can then use compactDAQ relay modules such as the NI 9481 and NI 9485 or a digital output module like the NI 9472.  All of these device can be programmed using the NI-DAQmx driver.

Alternately, you could use the USB-6525 which has eight solid state relays.
