National Instruments 781099-01 C Series Current Input Module
The National Instruments 781099-01 Current Input Module is a part of the NI-9227 Model series. With its integrated anti-aliasing filters and 24-bit Delta-Sigma ADC, this module provides accurate measurements that are essential for control and data acquisition applications. With a sampling rate that spans its four analog input channels from 1.613 kS/s to 50 kS/s, its main purpose is to detect current correctly.
Measuring power and energy consumption when paired with a C Series Voltage Input Module is one of the 781099-01's noteworthy characteristics. Applications like appliance and electronic device testing benefit greatly from this capacity. This module allows quality factor analysis, such as noise, frequency, and harmonics, beyond simple measurements. To guarantee accurate signal representation while rejecting unwanted out-of-band signals, the module combines analog and digital filtering. It differentiates between signals according to their frequency range, which includes alias-free, passband, and stopband bandwidths.
Important parameters for signal representation within the passband include phase linearity and passband flatness. The 781099-01 may export its own master timebase or take an external one, with an internal master timebase frequency of 12.8 MHz. A common master timebase source is necessary for modules to synchronize their data rates. A low-power sleep mode is supported by the 781099-01; however, its availability varies based on the chassis in which it is mounted.
The module uses the least amount of power when it is in sleep mode, which lowers the total power consumption and heat dissipation of the system. Strict isolation voltage norms are met by the 781099-01. It regulates channel-to-channel and channel-to-earth ground voltages within predetermined bounds, supported by validated dielectric withstand tests, to provide safe operation.
