The National Instruments BNC-2111 is a robust and versatile shielded connector block designed to enhance connectivity between data acquisition (DAQ) devices and various measurement apparatuses across laboratory, production, and testing environments. This model, identifiable by part numbers 779347-01 and 779347-02, features 24 BNC connectors and a single 68-pin I/O connector, facilitating ease of connection for analog I/O, counter, trigger, and user-defined signals. Engineered to maintain signal integrity in electrically noisy environments, the BNC-2111's shielding technology ensures reliable performance even in demanding industrial settings. Each of the BNC connectors on the front panel simplifies the cabling process, while the included two-position switch allows users to select between ground-referenced and floating source analog input signals. Specifically designed for use with M Series and E Series DAQ devices from National Instruments, this connector block should not be used with other device types. Although the BNC-2111 has been designated as obsolete by National Instruments, it will continue to be available for purchase and service through Apex Waves. The compact dimensions of 7.4 by 3.5 by 2.0 inches enable convenient placement, whether on a desktop or mounted via an optional DIN rail kit. Each unit is supported by a 2-3 year warranty and includes access to user and maintenance manuals for comprehensive guidance. For pricing, please contact a sales representative.
