CDAQ-9188XT National Instruments

CDAQ-9188XT National Instruments Programmable controller

Product  Description：

The National Instruments cDAQ-9188XT is an 8-slot CompactDAQ Ethernet chassis designed for distributed or remote data acquisition in extreme environments. As part of the "XT" (Extended Temperature) series, it is specifically engineered to maintain high performance and reliability under conditions that would cause standard commercial electronics to fail. It serves as the foundation for a modular measurement system, allowing users to mix and match various C Series modules to measure electrical, mechanical, or environmental signals.

Key Product Parameters

• Slot Count: 8 slots for C Series I/O modules.

• Network Interface: Standard 10/100/1000 Base-TX Ethernet (Gigabit Ethernet).

• Timing and Synchronization: Built-in NI-STC3 timing and synchronization technology for high-speed data streaming and advanced triggering.

• Internal Counters: 4 general-purpose 32-bit counters/timers.

• Operating Temperature Range: -40 °C to 70 °C (industrial-grade thermal performance).

• Shock and Vibration Resistance: Rated for 50 g shock and 5 g vibration, making it suitable for mounting on vehicles or heavy machinery.

• Input Voltage Range: 9 VDC to 30 VDC.

• Power Consumption: Approximately 15 W maximum (excluding modules).

• Software Compatibility: Fully compatible with NI-DAQmx driver software, LabVIEW, C/C++, and Python.

Major Product Advantages

• Extreme Environmental Resilience: The most significant advantage of the cDAQ-9188XT is its ruggedness. While standard chassis are limited to 0 °C to 55 °C, the XT version operates reliably down to -40 °C and up to 70 °C, eliminating the need for expensive external heating or cooling enclosures in many outdoor or industrial settings.

• Flexible Distributed Architecture: The Ethernet connectivity allows for long-distance measurements. Since the chassis communicates over a standard LAN, you can place the measurement hardware close to the sensors and transmit data back to a central PC over hundreds of meters, reducing noise from long analog sensor wires.

• High-Performance Streaming: With its Gigabit Ethernet interface and NI-STC3 technology, the chassis supports high-bandwidth data transfers, enabling simultaneous high-speed measurements from multiple modules without data loss.

• Modular Versatility: The 8-slot design supports over 50 different C Series modules. This allows you to combine analog inputs, digital I/O, and counter/timers in a single compact footprint to meet specific project needs.

• Ease of Deployment: Because it uses standard Ethernet, the cDAQ-9188XT can be easily integrated into existing network infrastructures, making it ideal for facility-wide monitoring or large-scale structural testing.

Critical Considerations and Precautions

• Module Compatibility: To achieve the full -40 °C to 70 °C operating range, you must ensure that the C Series modules inserted into the chassis are also rated for "Extended Temperature." Standard modules may limit the overall system temperature range.

• Power Supply Quality: Given its use in industrial environments, it is vital to provide a stable 9 V to 30 V DC power source. In high-vibration environments, use the built-in screw-terminal power connector to prevent accidental disconnection.

• Thermal Management: Although the device is rated for high temperatures, it still requires adequate airflow. When mounting the chassis in a confined enclosure, ensure there is sufficient clearance for heat dissipation to prevent internal components from reaching their thermal limits.

• Ethernet Shielding: For applications in high-EMI (Electromagnetic Interference) environments, use shielded Cat5e or Cat6 Ethernet cables to maintain data integrity and prevent network drops.

• Firmware Updates: Always ensure the chassis firmware is updated via the NI Measurement & Automation Explorer (MAX) to maintain compatibility with the latest versions of LabVIEW and the NI-DAQmx driver.

Common Product Applications

• Automotive and Engine Testing: Monitoring temperature, pressure, and vibration in engine test cells or during on-road vehicle testing where exposure to heat and vibration is constant.

• Aerospace Structural Testing: Deploying the chassis on aircraft frames or in hangars to capture strain and stress data across large structures using distributed Ethernet nodes.

• Oil and Gas Monitoring: Used for remote wellhead monitoring or pipeline inspections where equipment must survive harsh outdoor temperatures and rugged transport.

• Heavy Machinery Health Monitoring: Mounting directly onto industrial equipment, such as turbines or mining machinery, to perform continuous predictive maintenance and vibration analysis.

• Renewable Energy Research: Data logging for wind turbines or solar installations located in climates with extreme seasonal temperature fluctuations.
