Overview

Product overview

Key product information and technical features.

The TC-2095 provides thermocouple connections for SCXI-1100 and SCXI-1102/B/C modules. Rear switches configure signal referencing independently for each channel.

  • Isothermal construction reduces temperature gradients across thermocouple junctions.
  • Integrated thermistor senses cold-junction temperature.
  • Switchable pull-up resistors support open-thermocouple detection.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Which SCXI modules are recommended?

NI lists SCXI-1100 and SCXI-1102/B/C. Its terminal-block datasheet does not recommend TC-2095 use with SCXI-1104/C.

Are there thermocouple-type precautions?

Yes. NI warns that copper connector contacts can introduce offset errors with T-, R-, and S-type thermocouples.
