Description
The National Instruments PCI-7833 Multifunction Reconfigurable I/O Module provides versatile input mode options including DIFF (Differential), RSE (Referenced Single Ended), and NRSE (Non-Referenced Single Ended). For channel configuration, the DIFF mode utilizes two AI lines per channel, whereas the RSE and NRSE modes utilize only the positive AI line per channel.
It is equipped with an onboard instrumentation amplifier that offers high impedance and is capable of common mode voltage rejection. In terms of signal connection, for DIFF mode, the positive AI connects to the positive terminal, and the negative AI connects to the negative terminal. In contrast, for RSE mode, the positive AI connects to the positive terminal with the negative input connected to AIGND, and for NRSE mode, the positive AI connects to the positive terminal with the negative input connected to AISENSE.
The module’s amplifier output provides a differential signal relative to the device ground, and it includes an ADC (Analog-to-Digital Converter) for measurement with output voltage capability. Lastly, all signals must be referenced to ground, which can be done either at the source device or at the NI PCI-7833 itself.
