Description
The SCXI-1521B is a specialized module designed for static and fatigue structural tests, particularly with 120 Ω quarter-bridge strain gauges. This model falls under the SCXI & Legacy category and carries part numbers 190939C-02L and 777966-21B. It is engineered to provide precise and reliable measurements essential in various testing applications.
Each channel of the SCXI-1521B is equipped with a fixed-gain amplifier and a fixed 2-pole Butterworth filter, ensuring high-quality signal processing. The module also features a programmable excitation source, offering individual 0-5 V for every channel, which is vital for accommodating different sensor requirements.
Regarding software compatibility, the SCXI-1521B supports NI-DAQmx 7.3 or later, along with integration capabilities with LabVIEW and LabWindows/CVI. This compatibility ensures that the module can easily integrate into existing setups or new deployments, providing a flexible solution for various applications.
For proper operation, the SCXI-1521B requires the SCXI-1317 Front-Mounting Terminal Block. There are also optional accessories available, such as the SCXI-1310 Connector and Shell Assembly and the TBX-96 DIN-rail Mounted Terminal Block, which offer additional flexibility and ease of use.
Concerning connectivity, the module uses a 96-pin DIN C male connector, ensuring a secure and reliable connection. The cables compatible with this unit include the SH96-96 shielded 1 m cable and the R96-96 1 m unshielded cable, providing options based on the specific shielding requirements of the application. The pin labels such as EX + X (sensor excitation), QTR X (quarter-bridge completion resistor), and AI X (amplifier terminal) are clearly marked for easy setup and troubleshooting.
