Hello,
My question is what would be the best interface to communicate with LabView? Is what I have enough for my instruments to communicate with LabView?I have the following equipment from NI:
-CFP-1808, 8 Slot Ethernet / Serial Interface (2)
-CFP-TC-120, 16-Bit Thermocouple Input Module (2)
-CFP-CB-3 Isothermal Connector Block (2)
-CFP-AI-112 16 CH, 16-Bit Analog Input Module (2)
-CFP-OA-210 8 CH, 12-Bit Analog Output Module (4)
-CFP-AO-200 8 CH, 12-Bit Analog Output Module (2)
-CFP-DIO-550, Digital Input/ Output Module (2)
-CFP-CB-1 Connector Block (10)
-PS-5 Power Supply, 24 VDC, 5 amps, Universal Power Input (2)
and the following instruments to which I want to connect my modules to:
-Mass Flow Controller-Brooks 5850e series N.C. Valve (or N.O. Valve with flow £2.5 slpm)
3.5 watts, +15 Vdc @ 35 mA, -15Vdc @ 180 mA
N.O. Valve with flow rate > 2.5 slpm:
10.5 watts, +15 Vdc @ 350 mA, -15 Vdc @ 350 mA
115 AC / 28 DC 1 amp
3 wires
Black - COM
White - NC
RED – NO

You left out the important part of the specification for the mass flow controller. It says it has a 0-5 VDC input voltage and a 0-5VDC ouput signal. The cFP-AI-112 will work for the analog input, and the cFP-AO-210 will work for the analog output.
Also, you don't list the brand for the pressure transducer, but since you list it as having 3 wires with a common, NC, and NO, it must be basically a switch that is opened or closed at a set pressure. The cFP-DIO-550 digital input module will be able to read that switch.
