Eugene Posted October 5, 2009 Report Posted October 5, 2009 Hi guys, Currently i need to produce 4 digital ouput with 3V. The 4 input will be activated from Labview itself. What kind of DAQ should i buy? Regards, Eugene Quote
dblk22vball Posted October 5, 2009 Report Posted October 5, 2009 most digital outputs are 5 V i Believe. It also depends on how much current you need to supply. A USB-6008 might work for you if you dont need a lot of current. Otherwise I would go with a USb Compact DAQ chassis (since it is powered), or if you need the 3 V only, you might need to go with a compactdaq relay module and feed 3 V through it. Quote
PaulG. Posted October 5, 2009 Report Posted October 5, 2009 Measurement Computing makes some good DAQ equipment, too. It's a little cheaper than NI's and it comes with LV drivers. Quote
Mark Smith Posted October 5, 2009 Report Posted October 5, 2009 I once used a NI 6541 and if I recall correctly, the digital outputs were configurable - I looked it up and they can be configured at 1.8, 2.5, 3.3, and 5.0. These are not inexpensive units, however. Mark Quote
