how to come true a constant temperature control through PCI 7344

[langtian]

I have one PCI-7344 to control three motors.I also need to come true a constant temperature control through 7344.

using "Analog Input"and "Analog Reference",is it possible to come true the control.

To come true it, what others I need?

Waiting for your answer!

Thanks

Langtian,

In general the PID control loop of the 7344 can be used for a wide variety of control applications. You can use the analog inputs to acquire the feedback signals and the analog outputs to control e. g. torque, flow rates and so on. For temperature control the board seems to be a bit oversized as temperatures typically change very slowly compared to the high control loop rates of the 7344 but this shouldn't result in a problem.

Please note that the "Analog Reference" Output can't be used for control tasks as this is a static analog output fixed to 7.5 V which can't be changed.
For more information about how to use NI motion control boards with analog feedback please refer to this link and to this document.
