Overview

nnnn

The NI cDAQ-9174 is a 4-slot NI CompactDAQ USB chassis designed for small, portable, mixed-measurement test systems. Combine

nnnn

the cDAQ-9174 with up to four NI C Series I/O modules for a custom analog input, analog output, digital I/O, and counter/timer

nnnn

measurement system.

nnnn

Modules are available for a variety of sensor measurements including thermocouples, RTDs, strain gages, load and pressure

nnnn

transducers, torque cells, accelerometers, flow meters, and microphones. NI CompactDAQ systems combine sensor measurements

nnnn

with voltage, current, and digital signals to create custom, mixed-measurement systems with a single, simple USB cable back to the

nnnn

PC, laptop, or netbook.

nnnn

The cDAQ-9174 has four 32-bit general-purpose counter/timers built in. You can access these counters through an installed,

nnnn

hardware-timed digital NI C Series module such as the NI 9401 or NI 9402 for applications that involve quadrature encoders, PWM,

nnnn

event counting, pulse train generation, and period or frequency measurement.

nnnn

The cDAQ-9174 chassis is shipped with the following:

nnnn

- AC/DC converter that plugs directly into the chassis

nnnn

- USB cable with a thumbscrew lock for strain relief

nnnn

Power cord sold separately.

nnnn

For conditions where EMI could be an issue, you can use the 7.0 mm EMI suppression ferrites to suppress EMI for BNC cabling to the

nnnn

chassis.

nnnn

NI-DAQmx driver software is shipped with every chassis and includes the following:

nnnn

- LabVIEWSignalExpress LE for simple data-logging applications

nnnn

- API for LabVIEW, ANSI C/C++, C#, and Visual Basic .NET
