8-Slot, USB CompactDAQ Chassis—The cDAQ-9172 provides USB connectivity for small, portable sensor measurement systems. The chassis features the plug-and-play functionality of USB to connect sensor and electrical measurements. It also helps you control the timing, synchronization, and data transfer between C Series I/O modules and an external host. You can use this chassis with a combination of C Series I/O modules to create a mix of analog I/O, digital I/O, and counter/timer measurements. The cDAQ-9172 also has four 32-bit general-purpose counters and timers. With multiple timing engines, you can run four hardware-timed operations simultaneously, with three independent rates for analog input.
