NI 9225

National Instruments has expanded its C Series data acquisition line with the NI 9225 300 V power measurement module as well as the NI 9235 and NI 9236 eight-channel strain gage measurement modules.

These modules are supported on NI C Series-based devices including the NI CompactDAQ plug-and-play data acquisition system, NI CompactRIO rugged control and acquisition system and NI Single-Board RIO embedded design devices. These three new modules expand the C Series I/O platform to more than 40 modules and add power quality testing capabilities.

Using the NI 9225 300 V measurement module, engineers now can make high-voltage measurements to test battery stacks or monitor power quality events. The analogue input module is designed for high-voltage waveform measurements, such as line-to-neutral as well as line-to-line measurements of 110 V power grids and line-to-neutral measurements of 240 V power grids. The NI 9225 has three simultaneously sampled channels at 50 kS/s for accurate three-phase power metering and power quality measurements such as flicker, harmonics and power factor.

The NI 9235 and NI 9236 strain gage modules deliver eight channels of simultaneously sampled 24-bit quarter-bridge strain gage measurements. The channel density and fast sampling rate of 10 kS/s per channel make these modules well-suited for structural health monitoring, dynamic mechanical test and impact test.

Engineers can synchronise up to eight modules in an NI CompactDAQ or CompactRIO chassis to create a 64-channel strain measurement system, and synchronise multiple chassis to the same clock or GPS signal for even higher-channel-count or distributed systems.

The intuitive NI LabVIEW graphical programming environment makes it easy for engineers to communicate to and read data from C Series I/O modules. Because of the enhanced software integration with I/O modules, engineers can use the LabVIEW programming environment to develop and deploy code across multiple C Series platforms to fit their specific project needs.

They can use the same LabVIEW environment to create a USB data logger with NI CompactDAQ, an industrial control or structural health monitoring system with CompactRIO or an embedded system with NI Single-Board RIO.

The NI 9225, NI 9235 and NI 9236 are priced at about Rs.75,004 ($1,499) each.
