National Instruments 777643-01 BNC Adapter module

The part number 777643-01 from National Instruments is the identifying part number for the BNC-2110 BNC Adapter module. This BNC Adapter module is designed to create a simple connection between the Data Acquisition modules and a measurement actuator. This BNC connector is compatible with E Series, S Series, and NI 671X/673X waveform generation multifunction data acquisition devices. This module features 15 BNC connectors, a terminal block with 30 pins for signal connections, and a 68-pin I/O connector that connects to the data acquisition devices. 

The 777643-01 supports up to eight differential analog input channels and users can connect their analog input signals to these BNC connectors and set the FS/GS switches based on the nature of the signal source. For floating signal sources, the FS position connects the amplifier's negative terminal to the ground through a resistor and capacitor network, while ground referenced signals can be measured by setting the switch to the GS position to avoid ground loop error. The device provides connectors for up to eight analog output channels and the configuration for analog outputs depends on the connected data acquisition device and the application requirements. For waveform generation and other analog output tasks, the FS switch position is recommended to ensure proper signal integrity.

The 777643-01 also features digital and I/O connections and the users can use the spring terminal on the front panel as well as the user-defined BNC connectors for the Digital signals. The BNC connector module has a maximum input voltage limit of 42 volts and is designed according to the EMC standards. 

This BNC adapter module has compact dimensions of 19.05 cm by 10.48 cm by 3.51 cm and is also lightweight only weighing approximately 125 grams. The device should only be operated in an environment with an ambient temperature between 0 degrees Celsius and 70 degrees Celsius. When not in use the adapter can be stored in an environment with a temperature between –55 degrees Celsius to 125  degrees Celsius to avoid degrading the device and affecting the overall performance with time.
