Description
The NI-9208 is a model in the C Series Analog Input category, designed for versatility and high performance in data acquisition applications. This module is available with different part numbers based on the type of connectivity and isolation provided: 785041-01 features spring terminals with 250 Vrms channel-to-earth ground isolation and is not conformally coated, 780968-01 and 780968-02 both offer D-Sub connectors with 60 VDC channel-to-earth ground isolation. The latter is conformally coated for additional protection in harsh environments.
It is specifically designed to be compatible with CompactDAQ/CompactRIO systems, offering a seamless integration for users within these ecosystems. The NI-9208 stands out for its high channel density, providing up to 16 analog input channels on a single module. This allows for the monitoring of numerous signals, making it an ideal choice for applications requiring multiple data points.
The module excels in precision measurements thanks to its 24-bit Delta-Sigma ADC and the ability to operate in a high-resolution mode. This mode is particularly effective at eliminating low-frequency noise of 50/60 Hz, ensuring accurate and reliable data capture. With a maximum sample rate of 500 samples per second, it balances detail and speed efficiently.
Electrical characteristics include an input impedance of 85 Ω and a modest power consumption of 282 mW in active mode, highlighting its efficiency in operation. The NI-9208 provides flexibility in connection options, offering both spring terminal and 37-pin D-SUB front connectors. The weight of the module varies slightly between the spring terminal version at 5.7 oz and the D-SUB version at 5.1 oz, reflecting the slight differences in physical construction.
