Pneumatic Cylinder Sequence using LabVIEW
 

Hi,

I need to generate a cylinder sequencing operation using LabVIEW.

I use a 5/2 solenoid operated DCV working at 24V.

I need suggestions on how to activate this DCV from NI DAQ 6009.:confused:

Obviously the 6009 cannot source 24V, so you're not going to be able to operate the DCV directly with the 6009 - you're going to have to build a small control circuit that interfaces the 6009 to a 24v source and the DCV. The 6009 also cannot source enough current to directly trigger most magnetic relays (and by that I mean it wouldn't source enough for all the relays I could find at the local Radio Shack). I generally end up having to create a small transistor switch that drives a relay to control devices like that. If you connect the USB-6009 digital output to the base input of the transistor switch, you can control the relay and thus control the solenoid.

You can get a good explanation of transistor circuits here: http://www.kpsec.freeuk.com/trancirc.htm
