Product Details

The NI PCI-6289 is a high-density high-precision M-series multifunction DAQ card built for PCI bus low-level signal measurement and closed-loop test systems. It supports 32 single-ended or 16 differential analog input channels with 18-bit high resolution, single-channel maximum sampling rate up to 625 kS/s and aggregate multichannel scanning rate of 500 kS/s. It integrates 4 analog output channels with 16-bit resolution and 2.86 MS/s update rate, 48 TTL-compatible digital I/O lines and two independent 32-bit, 80 MHz counter-timer channels, and part of digital lines support hardware-timed correlated operation. Users can select seven programmable voltage ranges including ±0.1 V, ±0.2 V, ±0.5 V, ±1 V, ±2 V, ±5 V and ±10 V to capture tiny sensor signals. It adopts NI-MCal calibration technology to deliver excellent long-term accuracy, and the 110 dB CMRR effectively suppresses power frequency noise and common-mode interference for low voltage signal measurement. The onboard 2047-sample FIFO buffer ensures stable continuous data streaming and reduces data loss risk during long-time multi-channel scanning tasks. Compared with PCI-6281, it expands analog input channels to 32 and adds more analog output channels, suitable for multi-point precision measurement and stimulus-response testing.

This DAQ card uses dual 68-pin VHDCI signal connectors for all I/O wiring, compatible with matched shielded cables and terminal blocks for low-level signal measurement. It supports analog triggering, digital triggering and flexible clock configuration. Users can synchronize this card with other NI DAQ hardware via the RTSI bus to build multi-board coordinated test systems. The dual 32-bit counter channels can complete pulse counting, frequency measurement, period capture and incremental encoder signal monitoring. Digital I/O lines can read external status signals and drive low-power TTL circuits for trigger routing and simple interlock control. It supports DMA data transmission to reduce CPU occupancy during continuous sampling, and built-in self-calibration compensates gain and offset drift to maintain stable measurement accuracy for precision logging tasks. Users can expand measurement functions by cooperating with SCC or SCXI signal conditioning modules to realize special sensor and high-voltage acquisition.

This multifunction daq card is widely used in strain gauge array testing, low-level multi-sensor calibration, laboratory precision measurement, closed-loop signal verification, product design validation, small batch manufacturing test stations and OEM high-density high-precision measurement equipment integration. It supports NI-DAQmx drivers, compatible with LabVIEW, LabWindows/CVI and C/C++ programming environments, so engineers can quickly develop high-resolution multi-channel data acquisition and analog output control programs. As a discontinued legacy M-series DAQ hardware, the PCI-6289 is mainly used for maintenance and spare replacement of existing precision measurement platforms. It can maintain reliable high-resolution scanning and analog output performance, retain mature test workflows and avoid the high cost of rebuilding the whole measurement system. Its operating temperature range is 0°C to 55°C, supporting stable continuous operation in laboratory and light industrial environments.
