NI PCI-6033E High-Resolution Multifunction DAQ Card

The National Instruments PCI-6033E is a 16-bit multifunction DAQ card that captures high-resolution analog signals across up to 64 single-ended or 32 differential input channels. Designed for industrial automation, research, design verification, production testing, and laboratory automation, this E Series card delivers precise measurements with differential nonlinearity typically within ±0.5 LSB and relative accuracy within ±0.75 LSB.

– Technical Specifications

Analog Input Characteristics

• DC input coupling with low input bias and offset currents

I/O & Timing
• 8 digital I/O lines
• Two 24-bit counters/timers
• 512 to 1,024 sample FIFO buffer
• Three DMA channels with scatter-gather support
• Analog and digital triggering from PFI0/TRIG1 pin or post-gain PGIA output

– Key Features

No analog outputs. Successive approximation architecture ensures measurement integrity across demanding signal chains. High input impedance minimizes loading effects on source circuits.

– Typical Applications

Process monitoring, sensor data logging, transducer characterization, signal conditioning verification, and multi-channel data collection in controlled laboratory environments.

– Compatibility & Integration

PCI bus interface via 100-pin female 0.05 D-type connector. Compatible with NI-DAQmx, LabVIEW, LabWindows/CVI, Measurement Studio, ANSI C, and .NET. Runs on Windows and Linux with NI-DAQmx driver support. Operating temperature range: 0 to 50 °C.
