Overview

Product overview

Key product information and technical features.

The PCI-6259 combines analog acquisition, analog output, and digital I/O on a PCI card in NI's M Series family. It is the PCI model, distinct from the PCIe, PXI, and USB versions of the 6259.

Analog inputs support 32 single-ended or 16 differential channels. The maximum sampling rate is 1.25 MS/s for a single channel or 1.00 MS/s aggregate across multiple channels; the multichannel figure is not a per-channel rate.

The PCI-6259 combines analog acquisition, analog output and digital I/O in an NI M Series PCI device. Its analog inputs can be configured as 32 single-ended channels or 16 differential channels.

The maximum analog input rate is 1.25 MS/s for one channel and 1 MS/s aggregate for multichannel acquisition. Signal connections use two 68-pin VHDCI connectors; consult NI's accessory guide for connector-specific restrictions.

16-bit analog input conversion with single-ended and differential channel configurations.
Seven analog input ranges from ±0.1 V to ±10 V.
Four analog output channels alongside 48 digital I/O lines.
Dual VHDCI I/O connections supported by NI's model-specific cable and accessory guide.
16-bit analog input conversion with single-ended and differential input configurations.
Up to 1.25 MS/s single-channel analog acquisition.
Dual 68-pin VHDCI signal connectors.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Is the PCI-6259 a PCI Express card?

No. The PCI-6259 uses PCI. NI lists PCIe-6259 separately as a different interface version.

Does 1.25 MS/s apply to every analog input channel?

No. The maximum is 1.25 MS/s for single-channel acquisition. Multichannel acquisition has a maximum aggregate rate of 1.00 MS/s shared across the acquired channels.

How many analog input channels does the PCI-6259 provide?

It provides 32 single-ended or 16 differential analog inputs with 16-bit resolution.

What signal connectors does the PCI-6259 use?

NI identifies the PCI-6259 as a dual-connector device using 68-pin VHDCI connections. Review the official accessory guide for cable and terminal-block limitations.
