Overview

Product overview

Key product information and technical features.

The NI 9215 acquires four voltage signals simultaneously. Independent track-and-hold amplifiers allow all channels to be sampled together, rather than sequentially through a multiplexed input.

NI offers screw-terminal, spring-terminal and BNC versions. The catalog's tagged part number, 779011-01, corresponds to the screw-terminal version; connector-specific wiring and isolation limits must be checked before installation.

  • Simultaneous acquisition across four differential voltage inputs.
  • 16-bit successive approximation register ADC architecture.
  • Buffered and conditioned input signals with independent track-and-hold amplifiers.
  • Channel-to-earth isolation; isolation ratings depend on the connector variant.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Is the NI 9215 a thermocouple input module?

No. NI identifies the NI 9215 as a four-channel C Series voltage input module with a ±10 V range, not a dedicated thermocouple input module.

Does the NI 9215 sample all four channels simultaneously?

Yes. It supports simultaneous sampling at up to 100 kS/s per channel.

Which connector corresponds to part number 779011-01?

NI identifies 779011-01 as the screw-terminal version. Confirm the physical module label and connector before selecting wiring accessories.

Are the input channels isolated from each other?

No. The specifications state that there is no channel-to-channel isolation. Channel-to-earth isolation ratings are connector-dependent.
