Product Details

The NI PCI-6031E is a high-density E-series multifunction DAQ card for PCI bus measurement systems, designed for multi-channel high-resolution analog acquisition and stimulus-response testing. It adopts successive approximation ADC architecture with 16-bit resolution, supporting 64 single-ended analog input channels or 32 differential analog input channels, and the maximum single-channel sampling rate reaches 100 kS/s. It is equipped with 2 analog output channels with 16-bit DAC resolution, 8 bidirectional TTL digital I/O lines and two independent 24-bit counter-timer channels. Compared with the PCI-6030E, this model greatly expands analog input channels, making it ideal for systems with a large number of sensors. The analog input provides multiple programmable bipolar voltage ranges from ±50 mV to ±10 V, and differential input mode delivers excellent common-mode rejection to suppress ground loop noise and electromagnetic interference in multi-sensor wiring environments. The analog bandwidth is 255 kHz, which ensures stable capture of low-level dynamic signals.

This DAQ card uses a 68-pin SCSI connector for all signal wiring, compatible with shielded cables, SCC and SCXI signal conditioning accessories for isolated, high-voltage and remote sensor measurement. It supports software trigger and external hardware trigger for analog scanning, and the RTSI synchronization bus enables clock and trigger sharing with other NI DAQ, digitizer and DSA hardware to build multi-board synchronized test systems. The dual 24-bit counter channels can perform pulse counting, frequency measurement, period capture and incremental encoder signal monitoring. The analog output channels can generate stable DC voltage and slow analog excitation signals, cooperating with massive analog input channels to complete multi-point sensor calibration, distributed parameter logging and closed-loop testing. Digital I/O lines can read external status signals and drive low-power TTL circuits for interlock control and status indication. The standard PCI form factor fits ordinary industrial PC chassis and uses bus-powered design without extra external power supply. It supports DMA data transmission to reduce CPU load during continuous multi-channel logging, and built-in self-calibration function compensates gain and offset drift to maintain stable measurement accuracy for long-running tests.

This multifunction daq card is widely used in thermal test stands, multi-point strain measurement, environmental monitoring systems, battery pack testing, small batch manufacturing test stations, OEM high-channel measurement equipment integration and aerospace component validation. It supports both traditional NI-DAQ and NI-DAQmx drivers, compatible with LabVIEW, LabWindows/CVI and C/C++ programming environments, so engineers can quickly develop multi-channel acquisition and control programs. As a discontinued legacy E-series DAQ hardware, the PCI-6031E is mainly used for maintenance and spare replacement of existing high-channel measurement platforms. It can maintain stable synchronous analog input and 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 reliable continuous operation in laboratory and light industrial environments.
