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

– 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.
