How to use labjack U12 to control solenoid directional valve with Labview in hydraulic system

Hi,

 

I need to control a solenoid operated direactional valve in hydraulic system with Labjack U12. I am using three relays but need some help on the vi. like which instrument drive I need to use etc....

 

The coil voltage for the solenoid valve is :  AC120V, 60Hz; AC110V, 50Hz 

 

My goal is to control this solenoid valve open/close at certin time, am using Labview 2011. Any advise would be helpful.

 

Thank you!

First figure out the hardware

First figure out the hardware.  Can you control your relays directly or do you need something in between?  Since this is a U12 we have to go back to some older sources, rather than our normal relay app note:

Then you can use LJlogger to control the digital lines as desired and confirm the relays switch.

Then you can go to LabVIEW and make calls to EDigitalIn and/or EDigitalOut to control the desired digital I/O lines.  Start with the Getting Started steps here:
