Connectivity Accessories

CompactRIO and NI CompactDAQ systems are designed to provide

flexible options for low-cost field wiring and cabling. Most C Series

modules have a unique connector block option to provide secure and safe

connections to your CompactRIO or NI CompactDAQ system. Table 2

contains all of the connector blocks available for C Series I/O modules.

Table 3 lists the recommended connector block accessories for each

C Series digital output and relay module.

The NI 9932 kit provides strain relief and operator protection from

high-voltage signals for any 10-position screw-terminal module.

The NI 9933 includes a screw-terminal connector with strain relief

as well as a D-Sub solder-cup backshell for creating custom cable

assemblies for any module with a 37-pin D-Sub connector.

The NI 9934 includes a screw-terminal connector with strain relief

as well as a D-Sub solder-cup backshell for creating custom cable

assemblies for any module with a 25-pin D-Sub connector.

The NI 9935 includes a screw-terminal connector with strain relief

as well as a D-Sub solder-cup backshell for creating custom cable

assemblies for any module with a 15-pin D-Sub connector.
