Overview

Product overview

Key product information and technical features.

The NI 9971 fits into the wiring-accessory layer of an NI measurement system. NI identifies it as a four-backshell kit for supported 3- or 4-channel C Series modules with 2-position connectors.

NI recommends the backshell kit particularly for hazardous-voltage connections and high-vibration applications. Its function is connection protection and strain relief rather than signal acquisition or processing.

  • Provides strain relief at supported module connections.
  • Provides operator protection from high-voltage signals at the connector.
  • Can be used with the NI 9976 terminal block plug.
