National Instruments Introduces New Ethernet Data Acquisition Platform

By DE Editors

National Instruments has announced the new Ethernet-based NI CompactDAQ modular data acquisition system. The new NI cDAQ-9188 chassis is designed to hold eight I/O modules for measuring up to 256 channels of electrical, physical, mechanical or acoustic signals in a small (25 by 9 by 9 cm) form factor. With more than 50 different I/O modules to choose from, engineers and scientists can build remote or distributed, high-speed measurement systems using standard Gigabit Ethernet infrastructure. In addition, NI CompactDAQ simplifies initial setup with zero configuration networking technology and a built-in, Web-based configuration and monitoring utility, according to the company.

NI CompactDAQ uses NI Signal Streaming technology to deliver high-bandwidth data over Ethernet to a host computer. NI Signal Streaming provides the ability to maintain bidirectional analog and digital waveforms continuously over a TCP/IP connection, according to National Instruments. With NI-STC3 timing and synchronization technology, each chassis also can manage up to seven separate hardware-timed I/O tasks at different sample rates, including analog I/O, digital I/O and counter/timer operations. The chassis operate in a temperature range of -20 to 55 degrees Celsius and can withstand up to 30 g shock and 3 g vibration.

In addition to the Ethernet chassis, the NI CompactDAQ platform includes a four- and an eight-slot USB chassis and NI C Series I/O modules. NI offers more than 50 C Series modules to use interchangeably in NI CompactDAQ systems, each of which is hot-swappable and auto-detectable for simplified setup
