Overview

Product overview

Key product information and technical features.

The PXIe-7847 combines analog input, analog output and digital I/O with a user-programmable FPGA for onboard processing and direct control of I/O signals. The supplied NI part number 784144-01 identifies the PXIe-7847R R Series Multifunction module.

Each analog input channel has a dedicated A/D converter, supporting simultaneous sampling, independent timing and triggering, and multirate acquisition. The module can be customized using the LabVIEW FPGA Module and supports peer-to-peer streaming for direct data transfer to other PXI Express modules.

Kintex-7 160T user-programmable FPGA with 512 MB onboard DRAM.
Eight 16-bit analog inputs with simultaneous sampling and selectable ±1 V, ±2 V, ±5 V and ±10 V input ranges.
Eight 16-bit analog outputs with a ±10 V range and a maximum update rate of 1 MS/s per channel.
48 bidirectional digital channels with 1.2 V, 1.5 V, 1.8 V, 2.5 V and 3.3 V logic levels.
Dedicated A/D converters support independent channel timing, multirate sampling and individual channel triggering.
Peer-to-peer streaming support for direct data transfer to other PXI Express modules.
