NI SCXI-1126

8-Channel Isolated Frequency Input Module

  • Programmable threshold and hysteresis per channel
  • Programmable gain and filter settings per channel
  • NI-DAQmx measurement services software to simplify configuration and measurements
  • 15 Hz to 128 kHz signal ranges up to +/-250 Vrms
  • 333 kS/s maximum sampling rate
  • SCXI-1600 (USB) is recommended for controlling this module; also compatible with NI M Series

Use the Configure System link above to configure an SCXI data acquisition system based on this module.

The NI SCXI-1126 has eight isolated frequency input channels. Each channel includes a frequency-to-voltage conversion circuit with programmable input range, threshold, hysteresis, and filtering. The SCXI-1126 can measure the frequency of analog and digital signals with voltage levels as high as 1,000 V. The output voltages of this module are multiplexed onto a single channel of a data acquisition device, so you can scan and acquire multiple frequency and analog input signals within a single high-speed scan operation.

You can use the NI SCXI-1600 USB data acquisition module with the SCXI-1126 to create a completely plug-and-play USB data acquisition system. An SCXI chassis is required to house the SCXI-1600 and assorted SCXI modules for a particular system. The NI SCXI-1000 chassis is capable of holding up to four modules and the NI SCXI-1001 can hold up to 12.
