Product Details

PCI DAS6402/16 Product Description

The Measurement Computing PCI-DAS6402/16 is a high-resolution, multi-channel data acquisition board engineered for demanding control system architectures where signal fidelity, channel density, and deterministic I/O performance are non-negotiable. Designed for PCI bus integration, this DAQ board delivers 16-bit analog resolution across 64 single-ended or 32 differential analog input channels, making it a cornerstone component in distributed measurement, process monitoring, closed-loop control, and multi-axis signal conditioning platforms. Whether deployed in laboratory automation, industrial test benches, power quality analysis, or SCADA-linked data acquisition nodes, the PCI-DAS6402/16 provides the architectural backbone for reliable, high-throughput analog signal management.

In modern industrial control architectures, the data acquisition layer is not an isolated subsystem — it is the sensory foundation upon which the entire control hierarchy depends. The PCI-DAS6402/16 is purpose-built to serve this role, bridging the physical process layer with the supervisory and control layers through precise, low-noise analog conversion. Its integration into a control cabinet or test rack enables engineers to consolidate multi-channel analog measurement, digital I/O, and counter/timer functions within a single PCI slot, reducing wiring complexity, minimizing signal chain length, and improving overall system coherence.

NANKMOS maintains verified in-stock inventory of the PCI-DAS6402/16, supported by pre-shipment functional testing and a 12-Month Warranty covering hardware defects and operational integrity. Each unit is dispatched with full traceability documentation, ensuring compliance with procurement and quality assurance requirements across industrial, research, and OEM deployment scenarios.

The PCI-DAS6402/16 achieves its full architectural value when deployed as part of a coherent, layered automation platform. At the control layer, it interfaces directly with industrial PCs or embedded controllers running real-time operating systems, feeding high-resolution analog data into supervisory logic engines. When paired with a Measurement Computing USB-1608GX-2AO or USB-2633 for distributed remote I/O nodes, engineers can extend the measurement network beyond the central rack without sacrificing channel synchronization or data integrity.

At the I/O layer, the PCI-DAS6402/16's 48-line digital I/O subsystem — organized via the 8255-compatible interface — integrates seamlessly with relay output modules, optocoupler isolation boards, and terminal block assemblies such as the Measurement Computing CIO-MINI37 or STA-16 screw terminal panels, which provide field-wiring breakout for the analog and digital channels. This eliminates the need for custom wiring harnesses and accelerates commissioning timelines in multi-channel test environments.

At the communication layer, the board's Universal Library (UL) driver stack enables direct integration with LabVIEW DAQ VIs, MATLAB Data Acquisition Toolbox, and DASYLab graphical programming environments, as well as OPC-DA/OPC-UA server middleware for SCADA connectivity. This positions the PCI-DAS6402/16 as a natural data source node within Wonderware, Ignition, or Siemens WinCC SCADA platforms, where it feeds real-time process variables into historian databases and HMI trend displays.

At the HMI layer, analog signals acquired by the PCI-DAS6402/16 are visualized through industrial panel PCs or operator workstations running SCADA clients. Integration with Advantech IPC-610 or Siemens IPC477E industrial computers provides the computational platform for running MCC's Universal Library alongside HMI software, enabling operators to monitor waveform trends, set analog thresholds, and trigger alarms based on real-time channel data.

At the power layer, the board draws its operating power directly from the PCI bus (+5V rail), eliminating the need for external power supplies and simplifying cabinet power budgeting. In high-density rack configurations, this is complemented by industrial ATX power supplies with active PFC and surge protection, ensuring stable bus voltage under simultaneous multi-board operation.

At the protection and isolation layer, field signals entering the PCI-DAS6402/16 should be conditioned through signal isolators or signal conditioners — such as the Measurement Computing SSR-RACK24 solid-state relay rack or third-party DIN-rail signal isolators — to protect the ADC inputs from ground loops, common-mode noise, and transient overvoltage events common in industrial field environments. This is particularly critical in power generation, chemical processing, and heavy manufacturing applications where EMI levels are elevated.

At the maintenance layer, MCC's InstaCal calibration and configuration utility provides automated self-calibration routines, channel gain verification, and board diagnostics without requiring external instrumentation. This reduces scheduled maintenance overhead and enables in-situ verification of ADC accuracy, ensuring long-term measurement traceability across the board's operational lifecycle.

Manufacturing & Assembly Automation: In automotive and electronics manufacturing lines, the PCI-DAS6402/16 serves as the central analog acquisition node for multi-axis force/torque measurement, vibration monitoring, and process parameter logging. Its 64-channel capacity allows a single board to monitor an entire assembly cell, reducing the number of DAQ boards required per station and simplifying system integration.

Power Generation & Electrical Testing: In power quality analysis and generator test benches, the board's 16-bit resolution and software-selectable input ranges enable precise measurement of voltage, current, and power factor signals from transducers and CTs. Its analog threshold triggering capability supports event-driven capture of transient fault conditions, complementing protection relay systems in substation automation architectures.

Petrochemical & Process Control: In refinery and chemical plant environments, the PCI-DAS6402/16 integrates with 4–20 mA transmitter signal conditioners to acquire temperature, pressure, flow, and level signals from field instruments. Its deterministic sampling capability supports closed-loop PID control applications where analog feedback latency must be minimized to maintain process stability.

Water Treatment & Environmental Monitoring: Municipal water treatment facilities deploy the PCI-DAS6402/16 for multi-parameter water quality monitoring — pH, dissolved oxygen, turbidity, and conductivity — where high channel counts and 16-bit resolution are essential for regulatory compliance data logging and SCADA integration.

Mining & Metallurgy: In ore processing and smelting operations, the board supports vibration analysis on rotating equipment (crushers, mills, conveyors) and temperature profiling in furnace control systems. Its robust PCI interface and wide operating temperature range make it suitable for deployment in ruggedized industrial PCs installed in control rooms adjacent to process areas.

Packaging & Material Handling: High-speed packaging lines use the PCI-DAS6402/16 for real-time weight verification, seal integrity testing, and servo feedback monitoring. Its 250 kS/s aggregate sampling rate supports multi-channel simultaneous acquisition at line speeds where slower DAQ systems would introduce unacceptable measurement latency.

Q1: Is the PCI-DAS6402/16 compatible with modern SCADA and OPC-UA architectures? Yes. The PCI-DAS6402/16 is supported by MCC's Universal Library, which provides a well-documented API for integration with OPC-DA server middleware (e.g., Kepware KEPServerEX, Matrikon OPC Server for MCC). For OPC-UA connectivity, the board's data can be bridged through OPC-DA to OPC-UA gateway software, enabling integration with Ignition, Wonderware System Platform, and Siemens WinCC OA SCADA systems. Direct LabVIEW and MATLAB integration is also supported natively, making the board suitable for both legacy and modern supervisory architectures.

Q2: What signal conditioning and isolation accessories are recommended for field deployment? For industrial field environments, it is strongly recommended to use signal isolators or signal conditioners between field transmitters and the PCI-DAS6402/16 analog inputs to prevent ground loop interference and protect the ADC from overvoltage transients. MCC's STA-16 and CIO-MINI37 screw terminal panels provide convenient field-wiring breakout. For 4–20 mA loop-powered transmitters, a precision current-to-voltage converter (e.g., 250Ω precision shunt resistor) should be used to convert the current signal to a voltage within the board's input range. In high-EMI environments, shielded twisted-pair cabling with proper grounding at a single point is essential for maintaining 16-bit measurement accuracy.

Q3: What does the 12-Month Warranty cover, and what is the lead time for in-stock units? NANKMOS's 12-Month Warranty covers hardware defects in materials and workmanship, including ADC channel failures, digital I/O malfunctions, and PCI interface faults identified under normal operating conditions. Each unit undergoes pre-shipment functional testing — including analog channel verification, digital I/O continuity checks, and PCI bus enumeration — before dispatch.
