Description
The Part Number 776572-26 refers to a product categorized under SCXI & Legacy, specifically the model SCXI-1126. This product is described as a CCA, SCXI-1126, Frequency to Voltage Converter, designed to convert frequency input signals into proportional voltage outputs.
It features 8 isolated channels, allowing for multiple inputs to be processed simultaneously without interference. The Input Frequency Ranges are quite versatile, spanning from 250 kHz to 128 kHz across 10 selectable ranges, catering to a broad spectrum of applications. Additionally, it is equipped with Lowpass Filters ranging from 1Hz to 1kHz, which include 4 selectable, 4-pole filters to ensure signal clarity by reducing high-frequency noise.
The Maximum Input Signal that the SCXI-1126 can handle is up to 250 V, with isolation and overvoltage protection also up to 250 Vrms, ensuring the device’s safety and longevity, whether powered on or off. This makes it particularly suitable for environments with high voltage levels.
Compatibility with NI-DAQmx software facilitates easy integration with LabVIEW, LabWindows/CVI, and Measurement Studio, offering flexibility in application development and deployment. Connection to the device is made possible through a 50-pin male ribbon cable rear connector and a 32-pin male DIN C front I/O connector, providing reliable and easy setup.
The device’s dimensions are compact, measuring 1.2 x 6.8 x 8.0 inches, allowing it to fit into a variety of setups without requiring excessive space. Despite its obsolete status announced by National Instruments, it remains available for purchase and repairs through Apex Waves, ensuring continued support for users.
For those requiring calibration, options are available. This includes NIST accredited calibrations through a third party for precise measurement needs, as
