This is the first time I have needed to use analog output. I have 15 pressure sensors that will each draw 4-6 mA at 10V. I want to use the NI 6514 to provide my power to these tranducers which will return a 4 - 20mA signal I will bring into and SCXI 1102 and PXI 6221. Looking at the specification maximum current output is 75mA. Is that per line, per bank or total? Will I need more of these cards or will one card be able to provide enough current?
If the 75mA is per bank I should have no problem, but my thinking is that the loads (sensors) are all in parallel to the common Vs and currents in parallel add. This would mean that if I was using all 32 outputs at +10V, I am looking at less than 2.5mA per channel that could be driven.
Please someone help clarify.
Sincerely,
William.
