Issue Details

When I go to order NI-9269 (4-Channel C Series Voltage Output Module) online, it lists NI 9971 Backshell for 2-pos connector block (qty 4) as a required item. What is this and do I need to order it?


NI 9269 comes with the connectors you need to connect the wires to the module (NI 9976 Front Mount Screw Terminal Block for 2-Position Plug Modules). However, NI 9971 backshell kit  is highly recommended, especially when the module is outputting hazardous voltages or when using the module in a high-vibration application. It provides strain relief and operator protection from high-voltage signals for any 2-position module.
