Six New NI Embedded System Modules Offer Higher Accuracy, Speed and Density
National Instruments today announced six new modules that expand the I/O capabilities of the NI CompactRIO reconfigurable embedded platform for industrial vibration monitoring and control. With the new modules, engineers now can perform high-fidelity acoustic and vibration measurements, achieve analog input sampling rates up to 800 kS/s, acquire industrial voltage signals up to ±60 V and use 32-channel modules to extend the channel density of CompactRIO systems. CompactRIO is a rugged, embedded control and acquisition platform that uses LabVIEW FPGA reconfigurable I/O (RIO) technology to deliver a high level of user customization and performance. The new modules include: § cRIO-9233: 4-channel, ±5 V, 50 kS/s per channel, 24-bit IEPE analog input module The cRIO-9233 delivers high-performance dynamic signal acquisition (DSA) measurements for industrial machine condition monitoring (MCM) and in-vehicle noise, vibration and harshness (NVH) testing applications. The cRIO-9233 offers high-fidelity, 24-bit analog input channels for up to four IEPE accelerometer or microphone sensors with advanced features such as antialiasing filters and smart transducer electronic data sheets (TEDS) sensor compatibility. At less than $325 per channel, the cRIO-9233 module lowers the price point for portable DSA applications and delivers 102 dB of dynamic range. Machine builders and automotive engineers can use the cRIO-9233 to add precision audio and vibration measurement capabilities to their embedded monitoring and control systems. “The cRIO-9233 24-bit IEPE module and the reconfigurable nature of the CompactRIO platform change the rules of vibration monitoring and machine control,” said Darren Lingafeldt, systems engineer for Nexjen Systems, a supplier of heavy-duty electrical test equipment and custom vibration monitoring systems. “We use the cRIO-9233 module with LabVIEW FPGA RIO technology to incorporate high-bandwidth vibration monitoring and machine analysis while performing high-speed control. The end result is a rugged, low-cost, embedded system that can be deployed in a variety of applications and environments where traditional vibration monitoring equipment would be unsuitable.” The cRIO-9221 module increases analog input acquisition rates to 800 kS/s, the channel density to eight channels and the voltage range to ±60 V for CompactRIO systems. Engineers now can directly connect to high-voltage industrial signals up to ±60 V. The module also offers up to 2,300 Vrms of isolation (withstand), eliminates the need for external signal conditioning hardware and offers a direct connection to the CompactRIO reconfigurable FPGA circuitry for low-cost sensor integration. The new cRIO-9425 module extends channel density of CompactRIO embedded systems with 32 high-speed digital input channels. Using the cRIO-9425 module with CompactRIO, engineers can create discrete control systems with up to 256 channels and digital loop rates exceeding 140 kHz. The cRIO-9425 contains an industry-standard 37-pin DSUB connector for a variety of low-cost connectivity options. “The cRIO-9425 high-density digital input module gives us the performance and I/O density to replace multiple control systems with a single CompactRIO chassis,” said Greg Sussman, an automation systems consultant with Process Automation Corporation (PAC). “We chose CompactRIO for a number of our more challenging control applications because of the I/O density and processing horsepower. CompactRIO decreased the system costs for many systems by more than 50 percent.” About NI CompactRIO About National Instruments Pricing and Contact Information
