Description

Overview

Essential details：PXIE-7858R NI PXI R Series Reconfigurable I/O Module

The PXIe-7858R (Part number: 784147-01) is a R Series Reconfigurable I/O Module developed by National Instruments. It is protected from over current and over voltage conditions. This module provides 8 analog inputs which have a data sampling rate of 1 MS/s, with a 16 bit resolution. Each channel has an AIGND pin. These input channels also have an AI- pin and AI+ pin. These pins enable the device to connect differential voltage signals. They also help develop the connection for single-ended voltage signals. The NI PXIe-7858R additionally has 8 analog outputs, which have a data sampling rate of 1 MS/s, with a 16 bit resolution. Each channel consists of an AOGND pin and an AO pin. These pins enable the user to connect the current to the device.

The NI PXIe-7858R offers connections for 48 digital I/O channels. Each connector has adjustable levels from 1.2 V to 3.3 V. These channels can be set as input or output channels. Connector 0 consists of 16 low channels. These channels can perform up to 10 MHz frequency. Connector 1 consists of 32 high-speed channels. These channels can operate up to 80 MHz frequency. The NI PXIe-7858R is structured with an FPGA module. The digital I/O channels are connected with the FPGA by buffers. It helps provide protection against under voltage and over voltage. It also helps protect from overcurrent. The device is equipped with 2 68-pin VHDCI I/O connectors. It has an embedded block RAM of 16,020 kbits with an onboard DRAM of 512 MB.

The device operates using the NI-RIO driver software which is compatible with software packages such as LabVIEW, LabVIEW Real-Time module, or LabVIEW FPGA module. The FPGA feature enhances the performance of the NI PXIe-7858R. It also provides control over I/O signals. Moreover, it brings the flexibility in the system adjustments and timings. The module is used for applications that need control and precise timing, including custom protocol communication and sensor simulation. This module can further be used for high-speed control. The NI PXIe-7858R can perform multi-rate sampling and operate an individual triggering of a channel.
