The high-performance cDAQ-9139 eight-slot controller includes Intel Core i7 dual-core processing and 32 GB nonvolatile storage for advanced data-logging and embedded monitoring applications. The processing power of the cDAQ-9139 makes it well suited to perform the online processing tasks required by complex applications such as image detection and machine life-cycle prognostics. You have the option to use a Windows Embedded Standard 7 (WES7) or LabVIEW Real-Time OS. Choose WES7 on the cDAQ-9139 to take advantage of the extensive Windows ecosystem of software and display capabilities made possible by LabVIEW software. LabVIEW Real-Time is recommended for long-term reliability and headless operation. The high-performance cDAQ-9139 also offers a wide array of standard connectivity and expansion options, including USB, Ethernet, serial, MXI-Express, and VGA display output. Check the product and driver documentation for OS-specific expansion capabilities.

Combine the cDAQ-9139 with up to eight C Series I/O modules for a custom analog input, analog output, digital I/O, counter/timer, and CAN measurement and logging system. Modules are available for a variety of sensor measurements including thermocouples, resistance temperature detectors, strain gages, load and pressure transducers, torque cells, accelerometers, flow meters, and microphones. CompactDAQ systems combine sensor measurements with voltage, current, and digital signals to create custom, mixed-measurement systems within a single system. The cDAQ-9139 has four 32-bit general-purpose counter/timers built in. You can access these counters through an installed, hardware-timed digital module such as the NI 9401 or NI 9402 for applications that involve quadrature encoders, PWM, event counting, pulse train generation, and period or frequency measurement.

NI-DAQmx driver software is shipped with every chassis and includes the following:
- API for LabVIEW, ANSI C/C++, C#, and Visual Basic .NET
- DAQ Assistant code generation for LabVIEW, LabWindows™/CVI, and Measurement Studio
- Example programs for all supported languages
- Measurement & Automation Explorer (MAX) for system configuration and test

The cDAQ-9139 WES7 option is shipped preinstalled with an evaluation version of LabVIEW and NI-DAQmx.
