Because the NI 9144 chassis is a modular expansion system, you have the flexibility to incorporate more measurement types and channels by plugging in additional I/O modules. Plus, attaching another expansion chassis adds even more module slots for your system. Not only are all C Series I/O modules automatically synchronized in each chassis, but all the expansion chassis in the network are synchronized with each other as well.
Each C Series module contains built-in signal conditioning and isolation for extended voltage ranges and industrial signal types, such as thermocouples, resistance, voltage, current, strain, and accelerometers. Like the NI 9144 chassis, all C Series modules are UL tested and operate in industrial temperature and shock environments. In addition, C Series I/O modules are reusable in other NI hardware platforms, such as embedded CompactRIO, USB NI CompactDAQ, and Wi-Fi data acquisition.
National Instruments provides direct hardware access to the input/output circuitry of each I/O module using LabVIEW FPGA elemental I/O functions, which gives you the ability to conduct onboard signal manipulation such as filtering, fast Fourier transform (FFT), PWM, waveform generation, and more. Plus, you can program more than 40 C Series modules for single-point analog and digital I/O with the easy-to-use NI Scan Mode in LabVIEW Real-Time. For a complete list of compatible modules, view the C Series Module Compatibility Chart. The NI 9144 modules are listed under the deterministic distributed I/O categories.
