SCXI-1321

National Instruments SCXI-1321 Offset-Null and Shunt Calibration Terminal Block
Features

• For Applications Using Strain Gauges, RTDs, or Thermistors
• Shielded for Quick, Convenient Signal Connections
• Manual Bridge Offset Nulling

The National Instruments SCXI-1321 terminal block provides a convenient method for connecting and disconnecting signals to your system. This terminal block is an ideal solution for large-channel-count temperature or voltage applications.

The SCXI-1321 adds nulling and shunt calibration to SCXI-1121 strain gauge applications. The front-panel trimming potentiometer allows you to manually null out the offset voltage of bridge transducers. Each channel includes shunt calibration circuits which are controllable as a group from software. Activating a switch on the terminal block connects a 301 k Ohm shunt resistor (Rcal) in parallel with the strain gauge. The nulling and shunt resistor are both socketed for easy customization.
