Can the M Series PCI 6221 control 24 VDC solenoid valves like the NI 9477?

Hi,

I am working on a project where three solenoid valves requiring 24 VDC and 8 Watts must be controlled by a PCI 6221 multifunction DAQ.
I read on the NI website that an external power supply and the NI 9477 can be used together to actuate solenoid valves.  Since I already have the PCI 6221,
I was wondering if an external power supply would allow the PCI 6221 to power the valves.

Sincerely,

Hey,

No, the M-Series board only supports TTL Signals on DIO as you will find in the user manual: http://digital.ni.com/manuals.nsf/websearch/8117DF4C5A29C95C862573020061023B

Hey,

Is there any way to control solenoid valves using the PCI 6221 DAQ card? Is it possible for the DAQ card to control a driver circuit for the valves?

If there isn't an alternate way to control the valves, which DAQ do you recommend purchasing to control 3 solenoid valves and a pressure transducer?

I am not familiar with the compactDAQ. Does the digital output module need to connect to a DAQ card within the computer? If not, how does it communicate with the computer?

Sincerely,

Tristram Jordan

Go to www.mcmaster.com and search for part number 8299K12.  Then use a digital channel to control it.

Hey,

You could use an 9162 Single Module Carrier with the NI 9477 C-Series Module as an example. But using cDAQ-9172 you will be more flexible and can use more than only one modul. I would suggest to call your local NI Office where you can talk to an ISR to get the best information of products regarding your constraints!
