NI SCXI-1125

8-Channel Isolation Amplifier

  • Programmable gain and filter settings
  • Programmable offset calibration
  • Signal inputs from ±2.5 mV to ±300 V
  • NI-DAQmx Measurement Services software to simplify configuration and measurements
  • 300 V isolation per channel
  • SCXI-1600 (USB) is recommended for controlling this module; also compatible with M Series

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

The National Instruments NI SCXI-1125 provides 300 Vrms of working isolation and lowpass filtering for each analog input channel. The NI SCXI-1125 architecture is ideal for amplification and isolation of millivolt sources, volt sources, 0 to 20 mA, 4 to 20 mA, and thermocouples. The module can multiplex these eight channels into a single channel of the DAQ device, and you add modules to increase channel count. The module also offers parallel mode operation for increased scan capability.

The SCXI-1600 USB data acquisition module can be used in conjunction with this module 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 SCXI-1000 chassis is capable of holding up to four modules while the SCXI-1001 can hold up to 12.
