NI PCI-DAS160216 Multifunctional Data Acquisition Card

The NI PCI-DAS160216 is a multifunctional data acquisition (DAQ) card developed by National Instruments (NI), belonging to NI’s mid-range DAQ product series—engineered to deliver integrated analog, digital, and counter functionality for medium-speed measurement and control tasks. Unlike single-function cards (e.g., analog-only or digital-only models), the NI PCI-DAS160216 combines 16-channel analog input, 2-channel analog output, 16-channel digital I/O, and 2 counters in one PCI card—eliminating the need for multiple hardware components and simplifying system design.

In automation systems, the NI PCI-DAS160216 acts as a “versatile data hub” for connecting sensors, actuators, and control systems. For example, in a small-scale water treatment plant, it uses 8 differential analog inputs to monitor pH levels, temperature, and flow rates (sampling at 50 kS/s), 2 analog outputs to adjust chemical dosing pumps, and 8 digital I/O lines to trigger alarm systems—all while logging data to a central PC via DMA transfer. Its balance of 12-bit resolution and 100 kS/s sampling rate makes it ideal for applications that require reliable data without the cost of high-end DAQ cards like the NI PCI-6259.

Compared to entry-level DAQ cards, the NI PCI-DAS160216 offers greater flexibility: its software-selectable analog input ranges (±0.5 V to ±10 V) accommodate both low-level sensor signals (e.g., strain gauges) and high-voltage industrial signals, while its 16-bit counters track events like pump cycles or valve activations. This versatility makes it a go-to choice for academic labs, small manufacturing facilities, and industrial test benches where space and budget are limited.

Core advantages and technical highlights

Multifunctional Integration Reduces System Complexity: The NI PCI-DAS160216’s all-in-one design (analog input/output, digital I/O, counters) eliminates the need to install multiple PCI cards—saving slot space and reducing wiring complexity by 40% compared to discrete solutions. For instance, a university physics lab studying thermal dynamics uses the NI PCI-DAS160216 to collect temperature data (analog input), control a heating element (analog output), and trigger a camera (digital I/O)—all with one card. This integration also simplifies software development, as users can manage all I/O through a single NI-DAQmx interface instead of multiple drivers.

Balanced Performance for Mid-Speed Applications: With 12-bit resolution and 100 kS/s sampling rate, the NI PCI-DAS160216 strikes a perfect balance between speed and cost for medium-speed tasks. Its ±0.05% FS analog input accuracy ensures reliable measurements for sensors like thermocouples (temperature) and pressure transducers, while the 10 kS/s analog output update rate is sufficient for controlling slow-to-moderate actuators (e.g., chemical dosing pumps). In a food processing plant’s oven temperature control system, the NI PCI-DAS160216 samples temperature every 20 ms (50 kS/s) and adjusts heating elements via analog output—maintaining temperature within ±0.5 °C, which meets FDA guidelines for food safety.

Flexible Software Ecosystem & Easy Deployment: The NI PCI-DAS160216 is fully compatible with NI’s industry-leading software tools, including LabVIEW and NI-DAQmx. NI-DAQmx provides pre-built functions for configuring I/O, triggering, and data logging—reducing setup time by 50% compared to custom driver development. For example, a small electronics manufacturer uses LabVIEW to build a test interface for the NI PCI-DAS160216: the interface displays real-time voltage readings (analog input), sends control signals to a DUT (digital I/O), and logs test results to a spreadsheet—all without writing low-level code. The card also supports legacy software (Traditional NI-DAQ), making it easy to upgrade older systems without rewriting existing programs.

Cost-Effective for Budget-Constrained Projects: At a lower price point than high-end DAQ cards like the NI PCI-6259, the NI PCI-DAS160216 delivers essential functionality for small businesses and academic labs. For example, a startup developing a portable air quality monitor uses the NI PCI-DAS160216 to sample 4 gas sensor signals (analog input) and control a fan (digital I/O)—achieving accurate measurements at a fraction of the cost of a high-end system. Its optional external power for digital I/O also lets users scale functionality (e.g., powering high-current relays) without upgrading to a more expensive card.

Typical application scenarios

In academic research, the NI PCI-DAS160216 supports undergraduate engineering projects in mechatronics. A student team designing a robotic arm uses the card’s 8 analog inputs to read potentiometer positions (joint angles), 2 analog outputs to control servo motor voltages, and 8 digital I/O lines to trigger limit switches (safety stops). The NI PCI-DAS160216’s 100 kS/s sampling rate ensures smooth joint movement (updating servo positions every 10 ms), while LabVIEW integration lets students visualize joint angles in real time—reinforcing concepts like closed-loop control. The card’s low cost also allows the lab to deploy 10 setups, enabling parallel student experimentation.

In small-scale manufacturing, the NI PCI-DAS160216 is used for quality control in printed circuit board (PCB) assembly. A PCB manufacturer uses the card’s 16 analog inputs to test 16 voltage regulators on each board (sampling at 50 kS/s), 2 analog outputs to simulate input voltages (0–10 V), and 2 counters to track the number of passing/failing boards. The NI PCI-DAS160216’s ±0.05% FS accuracy ensures precise voltage measurements (critical for detecting faulty regulators), while DMA transfer logs test data to a database for ISO 9001 compliance. This setup reduces manual testing time by 60% and lowers defect rates by 25% compared to manual multimeters.

In environmental monitoring, the NI PCI-DAS160216 powers a portable weather station for rural areas. The station uses 6 analog inputs to measure temperature, humidity, wind speed, rainfall, and solar radiation (sampling at 10 kS/s), 2 analog outputs to control a data logger and a solar charger, and 4 digital I/O lines to trigger anemometer calibrations. The NI PCI-DAS160216’s wide input range (±0.5 V to ±10 V) accommodates low-level signals from a thermistor (temperature) and high-voltage signals from a solar sensor, while its rugged environmental rating (0–55 °C) ensures reliable operation in outdoor conditions. Data is transmitted to a cloud platform via LabVIEW, enabling researchers to monitor weather patterns remotely.

Installation, commissioning and maintenance instructions

Installation preparation: Before installing the NI PCI-DAS160216, power off the host PC and confirm an empty PCI 2.1/2.2/2.3 slot. Wear an ESD wristband (±15 kV) and work on a grounded bench to protect the card’s analog circuits. Insert the NI PCI-DAS160216 firmly into the slot until the edge connector is fully seated, then secure it with a chassis screw. For analog/digital signals, connect sensors/actuators to the 68-pin SCSI-II connector via the NI TB-2707 terminal block—use twisted-pair shielded cables for analog inputs (to reduce noise) and 24 AWG wire for digital lines. If using high-current digital I/O (e.g., powering relays), connect an external 5 VDC power supply to the 2-pin header. Install the latest NI-DAQmx driver, then use NI Measurement & Automation Explorer (MAX) to detect the NI PCI-DAS160216 and run a self-test (verifying analog input/output, digital I/O, and counter functionality).

Maintenance suggestions: Calibrate the NI PCI-DAS160216 annually using a NIST-traceable voltage reference (e.g., NI 9172) to maintain ±0.05% FS analog accuracy—temperature fluctuations > 10 °C can degrade measurement precision. Inspect the 68-pin connector and terminal block quarterly: clean contacts with isopropyl alcohol (99.9% purity) and a lint-free cloth to remove dust or oxidation. If the NI PCI-DAS160216 experiences data dropouts, check the PCI slot for dust (clean with compressed air) or update the NI-DAQmx driver. Avoid exposing the card to humidity > 90% or temperatures above 55 °C—moisture can damage digital I/O circuits, and extreme heat reduces analog signal integrity. Replace the card’s internal configuration battery (available via NI’s spare parts program) every 5 years to retain calibration settings during power outages.
