National Instruments Corporation NI 9239 BNC, 4-Ch +/-10 V, 50 kS/s/Ch,24-Bit, Ch-Ch ISO AI Module
The NI 9239 BNC (Part Number: 780181-01) is a 4-channel, channel-to-channel isolated analog input module designed for use with NI CompactDAQ and CompactRIO systems. It features a ±10 V input range, 24-bit resolution, and supports simultaneous sampling at up to 50 kS/s per channel. The module uses BNC connectors for secure and reliable signal connections. Each channel is individually isolated, providing protection and noise immunity for high-accuracy measurements in noisy environments. The NI 9239 BNC is ideal for high-precision voltage measurements in applications such as structural testing, audio analysis, and general-purpose data acquisition.
