NI 9239 BNC, 4-Ch +/-10 V, 50 kS/s/Ch,24-Bit, Ch-Ch ISO AI Module (780181-01)

±10 V, 50 kS/s/ch, 24-Bit, Simultaneous Input, 4-Channel C Series Voltage Input Module
The NI‑9239 performs differential analog input. With channel‑to‑channel isolation, your entire system, including the device under test, is protected from harmful voltage spikes up to the isolation rating. In addition to safety, isolation eliminates measurement errors caused by ground loops because the front end of the module is floating. Designed for both speed and accuracy, the NI‑9239 is an effective general-purpose analog module because of its resolution, sample rate, and input range.
