National Instruments (NI) unveiled the Ethernet-based CompactDAQ modular data acquisition system
The 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 25 by 9 by 9 cm, rugged form factor.
NI’s CompactDAQ uses patented NI Signal Streaming technology to deliver high-bandwidth data over Ethernet to a host computer. NI Signal Streaming provides the ability to maintain bi-directional analogue and digital waveforms continuously over a TCP/IP connection. With NI-STC3 timing and synchronisation technology, each chassis also can manage up to seven separate hardware-timed I/O tasks at different sample rates, including analogue 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, making the system ideal for demanding test applications.
According to NI, the CompactDAQ platform includes a four- and an eight-slot USB chassis and NI C Series I/O modules.
