Replace Spring Terminal Connector For NI C Series Module

Updated Oct 25, 2020



  • NI-9974

  • I have a cDAQ/cRIO C Series Module (like the NI 9213), and some of the spring clamps on it are defective/damaged and will not hold the wire. Is it possible to replace spring terminal connector?
  • I lost the spring terminal to my C Series Module, can I replace it?

The spring terminal connector is replaceable. To replace the connector in your C Series Module:
  1. Get a replacement connector.
    • NI C Series devices work with a NI 9974 connector. There are two different Part Numbers 785502-01 and 196740-01. Your C Series module will decide which one you should get. To determine which connector is the one required for your module, refer to the Product Details section of the NI 9974 product page.
For example, if you had a NI 9213 then you would want to get part number 785502-01.
  1. If needed, remove the old connector from your C Series module.
    • There are screws located at the top and bottom of the connector block. Remove these screws and remove the connector block.
  2. Place the new connector into the module. Secure the connector block by screwing in the top and bottom screw of the connector block.
