The National Instruments NI-9975 Terminal Block Plug (Part Number: 196741-01) is engineered for optimal compatibility with C Series modules that feature 16-pin screw terminal connections. This terminal block plug facilitates direct and dependable module connectivity through its two included screw terminal connectors, effectively streamlining wiring and enhancing organization in industrial applications by reducing the need for complex cabling systems. Of particular note is the 6-pin male COMBICON connector that interfaces seamlessly with the 16-pin female screw terminal block, making it an essential tool for minimizing wiring complexity and ensuring tidy arrangements when connecting multiple devices. While C Series modules typically come with the necessary connectors, the NI-9975 serves as an excellent spare or an alternative solution for simplified multi-device configurations. Designed to maintain precise and efficient data transmission with C Series I/O modules, the NI-9975 features built-in strain relief and operator protection for D-SUB terminal blocks, significantly enhancing user safety and convenience. This not only decreases the likelihood of damage during operation but also guarantees secure connections. The NI-9975 is compatible with various terminal modules, including screw, D-SUB, and spring terminal types, while D-SUB modules may require additional front-mounted terminal blocks or a combination of cable and terminal blocks for optimal communication.
