National Instruments PXI-6071E

The National Instruments PXI-6071E is a PXI-based multifunction data acquisition module delivering 64 single-ended or 32 differential analog input channels with 12-bit resolution and 1.25 MS/s maximum sample rate. It integrates two 12-bit analog outputs, eight TTL-compatible digital I/O lines, and two 24-bit counters/timers for event counting, pulse generation, and timing operations. The module supports analog triggering and the PXI Trigger Bus for system synchronization. Software-selectable input ranges span ±10 V, ±5 V, ±4 V, ±2 V, ±1 V (bipolar) and 0-10 V, 0-5 V, 0-4 V, 0-2 V (unipolar). With its compact PXI form factor and 100-pin extended connector, the PXI-6071E integrates into diverse measurement and control architectures across power, petrochemical, and automation sectors.
