National Instruments PCI-6033E

The National Instruments PCI-6033E (Part Number: 777516-01) is a versatile multifunction data acquisition (DAQ) device designed for a wide range of industrial automation applications, including research, design verification, production testing, and laboratory automation. This DAQ features 64 single-ended or 32 differential analog input channels, which can be software-selected per channel for increased measurement flexibility. With a 16-bit resolution and a maximum sampling rate of 100 kS/s per channel, the PCI-6033E leverages a successive approximation analog-to-digital converter (ADC) to ensure high accuracy in data conversion.

Engineered for robustness, the device supports an input voltage range of ±11 V from ground and incorporates extensive overvoltage protection, allowing tolerances of ±25 V when powered on and ±15 V when powered off. Data handling capabilities are enhanced by the inclusion of a FIFO buffer with a sampling capacity of 512 to 1,024 samples, while three DMA channels facilitate efficient data transfers and support for interrupts, programmable I/O, and direct memory access, utilizing scatter-gather transfer modes for optimal performance.

The PCI-6033E guarantees reliable data capture, featuring high input impedance (100 GΩ in parallel with 100 pF) to minimize signal distortion, while overload protection maintains an input impedance of 820 Ω when powered off. Measurement fidelity is reinforced by minimal crosstalk and low input bias, achieving an adjacent channel attenuation of –75 dB and –90 dB for non-adjacent channels from DC to 100 kHz. Operating temperatures range from 0 to 50 °C, and storage temperatures withstand between –20 and 70 °C, with humidity tolerances of 10 to 90% for both PCI and PXI devices. The PCI-6033E is compliant with Installation Category I environments, making it an ideal choice for diverse industrial applications.
