Application and TechnologyM Series for TestFor test, you can use 16-bit, 250 kS/s analog inputs and 1 MHz digital lines with NI signal conditioning for applications including data logging and sensor measurements. Low-cost M Series devices are compatible with the NI SCC and SCXI signal conditioning platforms, which provide amplification, filtering, and power for virtually every type of sensor. These platforms also are compliant with IEEE 1451.4 smart transducer electronic data sheet (TEDS) sensors, which provide digital storage for sensor data sheet information.
M Series for ControlLow-cost M Series digital lines can drive 24 mA for relay and actuator control. With up to four analog outputs, two 80 MHz counter/timers, and six DMA channels, M Series devices can execute multiple control loops simultaneously. Low-cost M Series devices also have direct support for encoder measurements, protected digital lines, and digital debounce filters for control applications. With up to 80 analog inputs, 32 clocked digital lines at rates of 1 MHz, and four analog outputs, you can execute multiple control loops with a single device. For higher-count control loops, you can use M Series devices in conjunction and tightly synchronized with National Instruments analog output devices for 64 or more loops.
M Series for DesignYou can use the wide range of I/O – from 80 analog inputs to 48 digital lines – to measure and verify prototype designs. M Series devices and NI LabVIEW SignalExpress interactive measurement software deliver benchtop measurements to the PC. With LabVIEW SignalExpress interactive configuration-based steps, you can quickly create design verification tests. The fast acquisition and generation rates of low-cost M Series devices along with LabVIEW SignalExpress provide on-the-fly design analysis. You can convert your tested and verified LabVIEW SignalExpress projects to LabVIEW applications for immediate M Series DAQ use and bridge the gap between test, control, and design applications.
Hybrid-Slot-Compatible PXI ModulesPXI M Series modules are hybrid-slot-compatible so that you can use them in both PXI slots and the hybrid slots found in new PXI Express chassis. The PXI Systems Alliance specifies that hybrid-slot-compatible PXI modules use modified slot connectors to mechanically fit in both PXI slots and hybrid slots. This mechanical change:
Provides compatibility with past, current, and future PXI chassis Maintains existing product specifications Requires no software changes (application or driver) [*]Maintains speed and capability of all PXI communication (PXI Express signaling is not provided)However, hybrid-slot-compatible PXI modules do not include the pins used to implement PXI local bus communication, which is used for backplane SCXI control from the right-most PXI slot in PXI/SCXI combination chassis (NI PXI-1010, PXI-1011, PXI-1050, and PXI-1052). For these applications, NI provides unmodified PXI M Series modules that maintain the required local bus capabilities. Refer to the SCXI Control of PXI/SCXI Combination Chassis section in the Ordering Information section for part numbers.
Simultaneous and Intelligent Data AcquisitionWhen you need to obtain performance from a data acquisition device beyond the capabilities of a multifunction data acquisition device, National Instruments provides simultaneous sampling with NI S Series and intelligent data acquisition with NI R Series. The S Series architecture dedicates an analog-to-digital converter (ADC) per channel to provide higher aggregate sampling rates compared to multiplexed devices. S Series devices are ideal for applications including IF digitization, transient recording, ultrasound and sonar testing, and high-energy physics. R Series multifunction DAQ devices contain a field-programmable gate array (FPGA) that is reconfigurable using the LabVIEW FPGA Module. R Series multifunction devices combine analog input, analog output, and digital I/O on a single device. You can customize these devices to develop capabilities such as complete control over the synchronization and timing of all signals and operations; user-defined onboard decision-making logic; and digital lines individually configurable as input, output, counter/timers, pulse-width modulation (PWM), flexible encoder inputs, or user-defined communication protocols.
Industrial M SeriesWhen you need performance and accuracy from a data acquisition device in an electrically noisy or harsh environment, considerindustrial NI M Series devices. They offer a set of high-reliability features, including isolation, ±20 mA current I/O, 24 V digital logic levels, and digital debounce filters. Isolation prevents ground loops, rejects high common-mode voltages, and protects users and equipment from high-voltage transients. Four to 20 mA current loops are immune to most sources of electrical noise and voltage (IR) drops along extensive cable lengths. Sourcing or sinking 24 V digital I/O interfaces directly with pumps, valves, relays, and other industry-standard sensors and actuators; programmable debounce filters remove glitches and spikes from switches and relays connected to digital input lines.
Recommended AccessoriesSignal conditioning is required for sensor measurements or voltage inputs greater than 10 V. NI SCXI is a versatile, high-performance signal conditioning platform optimized for high-channel-count applications. NI SCC provides portable, flexible signal conditioning options on a per-channel basis. Visit ni.com/sigcon for NI signal conditioning resources. The NI PCI-6221 (37-Pin) offers a 37-pin D-Sub connector that lowers connectivity costs by 80 percent. The D-Sub connector makes the PCI-6221 (37-Pin) ideal for OEM applications; however, its connector is not compatible with SCC or SCXI signal conditioning.
Recommended Driver SoftwareNational Instruments measurement services software, built around NI-DAQmx driver software, includes intuitive application programming interfaces, configuration tools, I/O assistants, and other tools designed to reduce system setup, configuration, and development time. National Instruments recommends using the latest version of NI-DAQmx driver software for application development in NI LabVIEW and LabWindows™/CVI, ANSI C/C++, C#, Visual Basic .NET, and Visual Basic 6.0. To download the most recent version of NI-DAQmx software, visit ni.com/support/daq/versions. Linux and Mac OS X users can program M Series devices with NI-DAQmx Base driver software. M Series devices are compatible with the following versions (or later) of NI application software – LabVIEW, LabWindows/CVI, or Measurement Studio versions 7.x; LabVIEW SignalExpress 1.x; VI Logger 2.0; or LabVIEW with the LabVIEW Real-Time Module 7.1. M Series devices are not compatible with the Traditional NI-DAQ (Legacy) driver.

CoverageFactor = 3 σ
For example, on the 10 V range, the absolute accuracy at full scale is as follows:
GainError = 75 ppm + 25 ppm · 1 + 5 ppm · 10 GainError = 150 ppm
OffsetError = 20 ppm + 57 ppm · 1 + 76 ppm OffsetError = 153 ppm
