NI-9201 Connection Guidelines

  • Make sure that devices you connect to the NI-9201 are compatible with the module specifications.
  • You must use 2-wire ferrules to create a secure connection when connecting more than one wire to a single terminal on the NI-9201 with screw terminal or NI-9201 with spring terminal.

High-Vibration Application Connections

If your application is subject to high vibration, NI recommends that you follow these guidelines to protect connections to the NI-9201 with screw terminal or the NI-9201 with spring terminal:
  • Use ferrules to terminate wires to the detachable connector.
  • Use the NI-9927 backshell kit with the NI-9201 with screw terminal or the NI-9981 backshell kit with the NI-9201 with spring terminal.
