NI -9225 Analog Input Module Inquiry Item

Details

This NI -9225 is a C-series isolated analog input module, with 3 measurement channels and rated 300Vrms high voltage input range. Each channel is equipped with independent electrical isolation to suppress common-mode interference and protect acquisition equipment. It supports simultaneous sampling, built-in anti-aliasing filter, matched with CompactRIO and CompactDAQ chassis. It can collect AC and DC voltage signals, widely used for power quality monitoring, motor testing, transformer and high-voltage cabinet signal acquisition in industrial electrical test systems.
