National Instruments PXI-7841 PXI Multifunction Reconfigurable I/O Module

The PXI-7841 (Part Number: 780337-01) Multifunction Reconfigurable I/O Module is made by National Instruments. The device is equipped with a built-in Virtex-5 LX30 FPGA module, which enhances the system’s performance and flexibility. This device has 8 analog input channels and 8 analog output channels. Each channel can perform at 200 kS/s maximum per channel. The device uses DIFF, RSE, and NRSE as input modes. Each mode is software-selectable and applicable to all channels. All input and output channels have 16-bit resolution. The device has the conversion time of about 4μs. The NI PXI-7841 has an input impedance around 10 GΩ. This rating is parallel with 100pF. This model performs DC coupling and has a maximum working voltage is within ±12 V. This is applicable for both single and common modes.

The National Instruments PXI-7841 Multifunction Reconfigurable I/O Module has a bandwidth of 1 MHz for small signals. The bandwidth increases up to 500 kHz for large signals. The device has 96 digital I/O Lines. The device has three 68-pin female I/O connectors. The connectors are VHDCI type with high density.

The NI PXI 7841 Multifunction Reconfigurable I/O Module has ±24 V maximum working voltage from channel to channel. The NI PXI-7841 fulfills the EMC standards. These standards are essential for lab use, control, and measurement. An important fact to note is that this module is easily cleanable with a non-metallic and soft brush. In addition, this module is recommended for indoor use only.

PXI-7841 Mature Status has been announced by National Instruments, but the module will still be available for purchase and repairs by Apex Waves.
