The National Instruments part number 779347-01 corresponds to the BNC-2111 Connector Block, designed to facilitate the connection of various input signals in a robust and organized manner. With a compact design, the connector block measures 7.5 inches by 4.125 inches by 1.38 inches with a metal enclosure, and slightly smaller at 7.4 inches by 3.5 inches by 1.982 inches without it. It features 24 BNC connectors and a 68-pin male connector for seamless integration with selected M Series and E Series multifunction DAQ devices. This connector block supports a maximum working voltage of 42 V, ensuring safe and reliable operation within a specified range of 0 to 55 °C for active use, though it can be stored in conditions ranging from –55 to 125 °C. Designed for indoor applications only, it has a maximum operational altitude of 2000 meters and complies with essential safety and performance standards, including IEC 61010-1, EN 61010-1, UL 61010-1, and CAN/CSA-C22.2 No. 61010-1. Users must ensure configuration settings are correctly adjusted for the type of input signals, utilizing the RSE/NRSE switch as needed to prevent damage or electrical hazards. Proper installation requires following the setup guidance, employing appropriate cables, and verifying the device recognition through the NI MAX software for functionality testing.
