National Instruments PCI-7831 Multifunction Reconfigurable I/O Module
The NI PCI-7831 Multifunction RIO Module includes a client programmable FPGA with which the user can compose VIs that keep running in Windows or on RT software to communicate with FPGA VIs that keep running on the PCI-7831. The user can grow constant VIs with LabVIEW and the LabVIEW Real-Time Module, then download the VIs to keep running on an equipment focus with an ongoing working framework. The LabVIEW Real-Time Module enables users to utilize the PCI-7831 module in RT Series PXI frameworks being controlled continuously by a VI. The NI PCI-7831 is composed as a solitary point AI, AO, and DIO supplement to the LabVIEW Real-Time Module.
NI offers an assortment of links for interfacing signals to the NI PCI-7831. If the user has to build a custom link, a non-terminated protected link is accessible from NI. The SHC68-NT-S interfaces with the NI PCI-7831 VHDCI connectors toward one side of the link. The opposite end of the link is not finished. This link ships with a wire list distinguishing the wires that compare to every NI PCI-7831 stick. The user can utilize this link to rapidly interface the NI PCI-7831 signs that they have to their preferred connector. Work the gadget at or beneath the estimation category 1 set apart on the equipment mark. Estimation circuits are subjected to working voltages and transient stresses (overvoltage) from the circuit to which they are associated amid estimation or test. Establishment classifications specify the voltage levels that can be withstood in electrical conveyance frameworks.

National Instruments PCI-7831 Frequently Asked Questions
Question: Can I implement a lock-in amplifier using the PCI-7831 RIO card?
Answer: DSA would be recommended for building a lock-in amp system, since the PCI-7831 is a DAQ device with FPGA.
Question: What is the range of the I16 values to correspond with the -10 to 10 volts range for the PCI 7831?
Answer: The I16 ranges from -32768 to +32767 for the PCI 7831.
Question: Can I use my NI PCI-7831 with NI-DAQ?
Answer: No, the NI PCI-7831 is used with the NI-RIO driver and is not compatible with NI-DAQ.
