Hi Mehmet,
First I would suggest that you take a look at this document which will help you make sure that PCIe is the correct bus for you to use. If you have decided on using a PCI or PCIe card, then you can start comparing the specifications of your various sensors and actuators with the capabilities of the PCIe card. For your reference, here is the spec sheet for the PCIe-6353.
Some things to keep in mind:
- What kind of output do your sensors have? Are they analog voltage, pulse-width-modulation (PWM), variable resistance, etc?
- How many channels of each input type (analog, digital, counter) will you need in order to acquire signals from all your sensors?
- What kind of inputs and control signals do your actuators require? Analog voltage, PWM, etc?
- If your actuators need an analog voltage as the control signal, what amplitude? Can your DAQ card supply voltages high or low enough?
- Do your sensors output signals within the voltage input ranges of the DAQ card? Do they output PWM signals at a frequency that your DAQ card can tolerate as an input?
- How finely do you need to be able to control your voltage signals to your actuators? Check the absolute accuracy specs to make sure the DAQ card can meet that need.
- How much current are your sensors going to draw? Can the DAQ card source that much current?
I would suggest making a table of your sensors and actuators with all the relevant specs, then you can use that table to compare the specs of whatever DAQ card you like.
I hope that helps you. Without knowing more about the specifications of your sensors and actuators, the best I can tell you is that the 6353 can do analog input, analog output, ditial input, digital output, counter inputs (frequency measurement, edge counting, and some others), and counter outputs (pulse trains, PWM, etc.). It also supports both analog and digital triggering.
