National Instruments PCI-6033E – 64-Channel Multifunction Analog Input DAQ Card | E Series Platform
Engineering Background
The NI PCI-6033E is a high-channel-count multifunction data acquisition card from National Instruments’ proven E Series platform. Designed for demanding measurement applications, it integrates seamlessly into PCI-bus industrial PCs and engineering workstations running NI-DAQ or NI-DAQmx driver frameworks. The E Series architecture has been the backbone of laboratory and industrial data acquisition for over two decades, offering unmatched driver maturity, software ecosystem depth, and field-proven reliability.
Product Positioning
The PCI-6033E targets procurement engineers and system integrators who require high-density analog input with 16-bit resolution in a single PCI slot. It is the preferred choice for multi-sensor monitoring, structural health monitoring, environmental data logging, and automated test equipment (ATE) where channel count and measurement accuracy are both critical constraints.

- Dual AO Channels: Integrated analog output enables closed-loop control without additional hardware
System Architecture & Signal Flow
The PCI-6033E employs a multiplexed single-ADC architecture. All 64 single-ended (or 32 differential) channels are routed through a programmable gain instrumentation amplifier (PGIA) before conversion by the 16-bit successive-approximation ADC. Channel scanning order, gain, and coupling are fully software-configurable via NI-DAQmx tasks. The RTSI bus connector enables hardware-triggered synchronization with other NI DAQ, motion, and vision boards in the same chassis. Analog outputs are driven by independent 16-bit DACs with output amplifiers capable of sourcing ±5 mA.
Signal connectivity is via the 68-pin VHDCI front-panel connector, compatible with NI’s full range of terminal blocks (SCB-68A, TB-2715) and shielded cables, enabling noise-immune signal routing in industrial environments.

Technical FAQ
Q: Is the PCI-6033E compatible with PCIe slots?
A: No. The PCI-6033E requires a 32-bit 5 V PCI slot. It is not electrically or mechanically compatible with PCIe. For PCIe platforms, consider the NI PCIe-6321 or PCIe-6341.
Q: What is the maximum per-channel sampling rate?
A: The 100 kS/s aggregate rate is shared across all scanned channels. Scanning 10 channels yields 10 kS/s per channel; scanning 1 channel yields the full 100 kS/s.
Q: Can I use this card with Python?
A: Yes. NI provides the nidaqmx Python package (PyPI) with full E Series support. Compatible with Python 3.6+.
Q: Does the card include a terminal block?
A: The card ships without a terminal block. We recommend the NI SCB-68A or TB-2715 with an SH68-68-EP shielded cable, available separately.
Q: Is recalibration service available?
A: Yes. Contact [email protected] to arrange NIST-traceable recalibration with certificate issuance.
Q: What warranty is provided?
A: 90-day functional warranty against defects in materials and workmanship. Extended warranty available on request.
