cDAQ-9171 (NI CompactDAQ Chassis)
OverviewThe cDAQ-9171 is a bus-powered, 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-9171 also has four 32-bit general-purpose counters/timers that you can access through an installed, hardware-timed digital C Series module for applications that involve quadrature encoders, PWM, event counting, pulse train generation, and period or frequency measurement.
