Description
The product with part numbers 157222A-01L and 783589-01 falls under the category of C Series Analog Input, specifically model NI-9247. This model is equipped with 3 Isolated Analog Input Channels, designed to handle a sample rate of 50 kS/s per channel Simultaneously. It is compatible for current input with 1 A and 5 A nominal CTs, offering a measurement range up to 50 Arms (100 Arms instantaneous and ±147 Apeak).
For connectivity, the NI-9247 utilizes ring lug based connectivity to current transformers, ensuring a reliable and secure connection for accurate measurements. The device supports a wide range of software including NIDAQmx, LabVIEW, LabWindows/CVI, and Visual Basic .NET, making it versatile for various applications.
Regarding safety, it boasts isolation ratings of 480 Vrms between channels and 300 Vrms to Earth, highlighting its robust design for handling high voltages. The NI-9247 is tailored for AC measurements only, disregarding DC values, which makes it specialized for applications requiring precise AC current measurements.
The unit weighs 8.75 oz and is built to operate in extreme conditions with an operating temperature range of -40 °C to 70 °C and a storage temperature range of -40 °C to 85 °C. It can withstand a wide humidity range during both operating and storage phases: 10% RH to 90% RH and 5% RH to 95% RH (noncondensing) respectively, ensuring durability and reliability in varying environments.
For environments prone to vibrations, it is designed to handle up to 5 grms and 5 g (10 to 500 Hz), demonstrating its ability to perform under mechanical stress. Calibration services are available, including NIST accredited through 3rd party, and In-house basic calibration, with a recommended
