The cDAQ-9174 is a CompactDAQ USB chassis designed for small, portable sensor measurement systems. The chassis provides the plug-and-play simplicity of USB to sensor and electrical measurements. It also controls 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-9174 also has four 32-bit general-purpose counters/timers. With multiple timing engines, you can run seven hardware-timed operations simultaneously, with three independent rates for analog input.
