NI-9203
NI-9203 is a high-performance 8-channel C-series current input module designed specifically for industrial control and monitoring systems. This module supports an input range of ± 20mA, with 16 bit resolution and a maximum sampling rate of 200kS/s, and can accurately capture dynamic signal changes. Its core advantage lies in the dual isolation barrier (250Vrms isolation) from the channel to the ground terminal, which achieves electrical isolation between the signal and the power supply through independent isolation circuits, effectively suppressing electromagnetic interference and ensuring system safety. The module adopts bolt terminal connection method, compatible with sealed coating version to adapt to humid or corrosive environment, providing reliable physical connection and protection. This product is widely compatible with CompactRIO embedded systems, R series expansion cases, and CompactDAQ platforms, supporting NI DAQmx drivers and LabVIEW development environments. It is suitable for industrial automation, process control, and scientific research testing scenarios, providing users with high-precision and high reliability current signal acquisition solutions.
