Measurement Computing PCI-DAS6402/16 – 16-Bit High-Resolution Analog & Digital I/O DAQ Card | PCI-DAS6402 Series
Engineering Background
The PCI-DAS6402/16 is a high-performance data acquisition card developed by Measurement Computing Corporation (MCC), designed for demanding laboratory, industrial automation, and test & measurement applications. Built on the PCI bus architecture, it delivers 16-bit resolution across 64 single-ended (or 32 differential) analog input channels, making it a benchmark solution for precision signal acquisition in control systems and R&D environments.
Product Positioning
Targeted at procurement engineers and system integrators requiring reliable, high-channel-count analog I/O with deterministic digital control, the PCI-DAS6402/16 bridges the gap between entry-level DAQ cards and full DAS systems. It is a direct replacement and upgrade path for legacy ISA-bus acquisition hardware in modernized PCI-slot workstations and industrial PCs.

Engineering Advantages
- 16-bit resolution delivers 0.0015% full-scale accuracy — critical for precision process control
- 64-channel capacity reduces card count and chassis slots in multi-signal applications
- Programmable gain per channel eliminates external signal conditioning for mixed-range inputs
- Onboard FIFO ensures data integrity under high CPU load or OS interrupt latency
- 48-line DIO supports relay control, valve actuation, and status monitoring without additional I/O cards
- Dual 16-bit DAC outputs enable simultaneous analog setpoint generation for actuators or test stimuli
- Universal Library SDK provides consistent API across MCC product family — minimizing software migration effort
System Architecture & Signal Flow
The PCI-DAS6402/16 employs a multiplexed analog front-end with a single high-speed 16-bit ADC. Channel scanning is managed by an onboard sequencer that cycles through the selected channel list at the programmed scan rate. Acquired samples are buffered in the 1024-sample FIFO before DMA transfer to host memory via the PCI bus, ensuring continuous acquisition without sample loss. The 48-bit DIO subsystem operates independently via the 8255-compatible controller, allowing concurrent analog acquisition and digital I/O operations. The dual DAC channels update synchronously or independently under software or hardware trigger control.

Technical FAQ
Q: Is the PCI-DAS6402/16 compatible with Windows 10 64-bit?
A: Yes. MCC provides 64-bit drivers via the Universal Library (UL) v6.x and later. InstaCal configuration utility supports Windows 10.
Q: Can I use this card with LabVIEW?
A: Yes. MCC’s NI-DAQmx-compatible driver layer and dedicated LabVIEW VIs are available for seamless integration.
Q: What is the maximum aggregate sampling rate across all channels?
A: 250 kS/s aggregate. For 64 channels scanned sequentially, effective per-channel rate is ~3.9 kS/s.
Q: Does the card support simultaneous sampling?
A: No — the PCI-DAS6402/16 uses a multiplexed (sequential) architecture. For simultaneous sampling, consider MCC’s PCI-DAS6034E or USB-1616FS-Plus series.
Q: What signal conditioning is required for thermocouple inputs?
A: An external signal conditioner (e.g., MCC CIO-EXP32 or equivalent) is required to convert thermocouple millivolt signals to the card’s input voltage range.
Q: Is recalibration service available?
A: Yes. Konmask partners with certified calibration labs. Contact us for NIST-traceable recalibration with certificate.
