NI VXI-1200 FlexFrame, 9-Slot VXI Mainframe

The NI VXI-1200 FlexFrame is a 9-slot VXI mainframe engineered to integrate instrumentation and data acquisition modules in demanding test environments. This 5U rack-mount chassis accommodates up to six C-size VXI modules and three B-size VXI or VME modules, with configurable Slot 0 control via a plug-in Personality module. The mainframe delivers 720 W of total DC power and operates across 47 to 440 Hz input frequencies with automatic voltage ranging and power factor correction.
