Product Description
The National Instruments SCXI-1126 Frequency Input Module, with part number 776572-26, is a versatile and software programmable frequency input module that offers eight channels for comprehensive signal acquisition. Each channel can handle input frequency ranges from 250 kHz to 128 kHz and is equipped with four selectable, 4-pole lowpass filters with cutoff frequencies ranging from 1Hz to 1 kHz.
This module is designed to handle maximum voltages of up to 250 V for both digital and analog input signals, ensuring robust performance in a variety of industrial applications. The SCXI-1126 provides excellent isolation, with each channel separated from others and the chassis, up to 250 Vrms, offering enhanced safety and signal integrity.
Configuration and customization are straightforward and user-friendly, thanks to the module being fully software programmable, which allows for adjustments to frequency input range, threshold level, hysteresis level, and output filtering for each individual channel. The rear of the module houses a 50-pin male ribbon cable connector, while the front offers a 32-pin male DIN C I/O connector for flexible connectivity options.
Compatibility with NI-DAQmx driver software and application development environments such as LabVIEW, LabWindows/CVI, and Measurement Studio makes integration into existing systems seamless. The module can be configured using the Measurement & Automation Explorer tool, contributing to a user-friendly experience for technicians and engineers alike.
